The Proth Prime Search sieve has completed its initial testing period. We are now ready to add additional users. Because of the nature of this sieve (large sieve file), available slots will be limited. This will be limited to 10 at first. If all goes well, and as long as resources are available, we'll add more.
UPDATE - 24 September 2008: Project is open to all 64 bit users who request it.
UPDATE - 08 November 2008: Updated WU length and added more information about Wubi.
This project uses the same sr2sieve program as the PSP sieve and offers comparable BOINC credit. If you are interested, please PM Lennart and he'll enable the project in your PrimeGrid preferences.
Requirements to participate are:
1. 64 bit preferred but available for 32 bit as well
2. Linux, Mac, and Windows supported
3. 500 MB RAM per core (please see below for more "precise" measurements)
4. 2+ GHZ
Additional information
Time on a C2Q 2.4GHz is ~2 hrs
Idealy suited for multiple core CPU
At least GCC 4.2.0 on Linux - http://gcc.gnu.org/
PPS Sieve is set as beta project so that we can limit its distribution due to the size of the sieve file. Therefore, there is an override for WUs. BOINC first checks beta apps for work and as long as there's work available for PPS Sieve, your machine will only get that.
The only way to get other work is to deselect PPS Sieve every now and then to allow other work to be downloaded.
RAM Requirements
M = C*200 + O + U
Where:
M is minimum memory required, in megabytes
C is the number of cores
O is the operating system (Linux = 300, WinXP=500, Vista or Win7=800)
U is how you use the system (Dedicated cruncher = 0, used by a person = 500)
So, a dedicated Quad Core Linux cruncher could run in 4*200+300+0 or 1100 MB. But a Quad Core Vista machine that you actually use would need 4*200+800+500 or 2100 MB.
Basic Stats
Proth Prime Search (Sieve) at Free-DC
32 bit OS with 64 bit CPU
This is for those who are "driving with the hand brake active" (running a 32 bit OS on a 64 bit machine) ;) Wubi is a very nice tool that installs Ubuntu as a dual boot to your 64 bit machine. It's as simple as adding a program to Windows. You can even uninstall it like you would any other program. :)
Wubi - Ubuntu Installer
After getting 64 bit OS running on your machine, here's a link to ALL BOINC clients (including Linux x64): http://boinc.berkeley.edu/download_all.php If you are new to Linux and need help getting set up, let us know.
It really is simple. :)
Ubuntu has a power save feature that throttles the CPU frequency down to save power. It does not treat BOINC as an active program so will throttle down thus causing under-performance. For those downloading the latest Ubuntu 8.10, please follow these directions to make sure the frequency is not throttled down while BOINC is running:
1. In Ubuntu, right click the top menu bar
2. Select add to panel
3. Select "CPU Frequency Scaling Monitor"
4. Click add
This will add a processor icon to the top menu. Click on the icon and set to "Performance". This also allows you to see the CPU frequency.
ATTENTION: While this project is BOINC oriented, it is still very much within the Project Staging Area guidelines...meaning, it will not be as fail-safe or as "clean" as regular PrimeGrid BOINC projects. There will be quirks and idiosyncrasies unique to this project. Consider PPS sieving in a long term "beta-phase". However, please continue to post your experiences so that new users are aware of them.
Thank you!
UPDATE - 09 October 2008: Project is running stable

Cool.
Unfortunately, I don't have any 64bit OS installs around.
I assume the PPS LLR <200k continues until completion, and the sieve is to prepare the way for moving the PPS LLR into BOINC?

PPS LLRNet will continue until it enters PG BOINC. Our first goal is n=200K but it would be nice to reach n=300K before starting BOINC. The higher, the better...it will help minimize the stress on the server.
Therefore, we still need a lot of help on port 300. We are currently at n=181K. Anyone intersted in helping, please see this thread.

I will only be participating in Primegrid until the end of the month, will also be taking part in the "lunar challenge", but all my machines (Seven; 2 quads, 3 duals, and 2 singles)fit the requirements if they'll be of assistance during that period.
[edit]after further reading, I suspect this requires manual work. I work 10-12 hr days. Don't have time for manual stuff, so if it is, then I'm afraid I can't help[/edit] |

They let me join their band of merry men. Only to find out that Mandriva 2007 Spring Free X86-64 doesn't have GCC4.2.0 (it has GCC 4.1.2 max) which also seems to be a requirement, as all my work immediately when to "Computation Error". They've provided a link to an ftp download site for Mandriva 2008 Spring Free X86-64, I downloaded all the files, but Nero doesn't seem to want to allow me to burn the ISO image. Until I figure that out, I can't participate. |

@popandbob.
Its a sieving sub-project so I'd put your P4 on PRP'ing and not Sieving as the P4s perform badly at sieving. Similarly, Athlon XPs (not 64s) are hopeless at LLR'ing but are great at sieving.
My Q6600 @ 2.4GHz running Win 64 Pro SP1 takes approx 3hr25min per PPS task per core. It has 3 cores on PPS and 1 core on Folding @ Home's GPU2 client for nVidia 8600GT graphics card (1746 PPD according to FAHspy).

I had just three WU which had a very abnormal behaviour of the percentage status bar.
They hab been advancing to about a half percent, where they then stayed for about three hours.
The user was short before entering panic mode, but then they jumped to values about 95% and finished well around 3h 20min and i calmed down again.
But there seems to be a little problem with the status bar.
At least on my Q6600 with xp64 and boinc 6.2.6
For example:
34137893
Also the sorting of the tasks per Computer seem to be strange. This WU is somewhere on the last pages, while it should be on the first or second.

I have added an ATTENTION section to the first post. We appologize for all the little quirks in the project. They did not present themselves during the initial testing phase.
Please read the ATTENTION section and only continue if you're able to live with those conditions.

A note here from Rytis a while back in PM's but I thought I should just let everyone know that if you do work in LLRNet he says he will give the Work units you've done over to the project side when ever that particular project goes live.
"Hello,
sorry for the delay, I'm extremely busy these days (starting my own company), so not much time is left for PG.
We will add the amount of manual work done to user's page, however, I can't give any estimate to when it's going to happen. Right now all I can do is limited maintenance."
Just some info to keep the PPS people like myself alive and kicking :)

PPS Sieving Update
PPS sieve is approaching 57T complete. This is an excellent accomplishment so far. We currently have 23 users but only 9 were active in the last 24 hours.
For a few days, 1T/day was sustained. However, now the rate is about 500G/day. While our initial goal is 100T, our extended goal is up to 1P (1000T). As you can calculate, that still leaves plenty of work to do. At 4T/day, that still puts us over 235 days to reach 1P.
Thank you to everyone who has contributed to the sieve. If there is anyone else interested in sieving PPS, please see the first post in this thread.

Today all WUs on my C2Q are crashing after 15 seconds, e.g. http://www.primegrid.com/result.php?resultid=52414319. :|
I was running BOINC 6.2.16, but problem persists after downgrading to 5.10.45.

PPS Sieving Update
PPS sieve is still OPEN for crunchers!!! :)
PPS sieve is approaching 65T complete. We continue to move forward, albeit at a much slower pace. However, any progress is good progress. :D
Remember that our intial goal is 100T and our extended goal is up to 1P (1000T).
Thank you to everyone who has contributed to the sieve. If anyone is interested in sieving PPS, please see the first post in this thread for requirements.

I don't think it will be "open" on Boinc! Not the sieving.
The sievefile is to big.

It look's like that !! If you look again you will se that server add all time to keep 1000 task in a buffer ( thats what you see in frontpage)
When it goes below 1000 it will add more all time.
This first batch has ~400 000 wu and it is only n=200K-220K :)
When this 400 000 wu is complete we will add n=220k-240k
So there is time to sieve. :))

Wouldn´t it be possible to make this subproject public? I know, Bandwith and server load are the biggest problems then.
Isn´t it possible to make a "maximum number of downloads" of the sieve file? Or a "maximum number of testers"?
I think this would help PPS Sieve gaining more speed.

Make the (big) sieve file available by torrent or any free filehoster, ready to download for all, reducing server bandwidth.

I'd be interested in giving this a try if it were possible, but I'm not very computer technical, so I don't know if I meet the requirements (please don't laugh).
I'm running Windows XP SP2. My system info says this:
Gateway MX6426 AMD Turion 64 mobile technology ML-40 (does this mean 64-bit?)
2.19 GHz, 960 MB of RAM
What other info would you need to know/how would I find it? |

First, you will need to run 64-bit OS, which you don't (Win XP SP2).
Anobody who wants to participate in PPS Sieve would need to run Win XP x64, Windows Server 2003 or 2008 x64 or Vista x64 (or 64-bit Linux).
This is the first step to enable benefits of 64-bit processor/extension.

Please see the ATTENTION section in the first post in this thread.
The PPS Sieve stats page here is used just to monitor work flow i.e. when to insert more work. We only use the 4 columns Total Tasks, Queued for Download, In Progress, Completed. The other two columns are not being calculated.
As Lennart pointed out, the sieve was introduced to BOINC after 25T (25000G) had been completed. Therefore, when looking at the Total Tasks and Completed columns, add 25000 to get the correct status in G.
Queued for Download lists the remaining tasks in the current range.
To see how many factors are being found, please see PrimeStats.net Proth Sieve page.

Well, I passed the word over at my group (something we all should do) about the importance of sieving, whether PPS or otherwise. I like the "furthering research" angle, but most seem interested only in advancing a cobblestone score, and won't contribute unless they see something in it for that (big credit).
Whenever you need Proth help, I'll be here. Any chance there'll be a Mac-client?

I have two 64 bit hosts that I added PPS Sieve to and now that is all that I am getting, even though I have GCW Sieve and PSP Sieve selected in my preferences. Is this something that was expected to happen? Just curious as I have no problems with doing only the PPS Sieve it just struck me as an odd behavior.

Some problems with the sieve stats at the moment? (http://www.primegrid.com/stats_pps_sieve.php)
Just a little feedback at this point:
Crunched nearly 1k PPS WUs now and never had problems with them...

I wonder if there's a common cause? Perhaps the server load?

The only thing is that i get this BOINC message (about 10 times in the last 5 days):

"This means that when you tried to report work and get some new the server load was high, so the connection timed out, but it still assigned work and marked your reports as completed, so when you contacted the server again it tells you that it resends you work that was lost because of connection timeout"

The new sr2sieve (v1.8.2) app. for PPS Sieve has been re-released. :)
Please let us know if you have any issues regarding priority. Also, please feel free to post your observed speed improvements. :)
First observations show both Linux and Windows running at low priority. However, resend WU's will still have -Z so you might see "above normal" occasionally. If you do, first look to see if the WU is a resend. Anything that ends with _1 or _2 ect. will be a resend. We do not anticipate many of these.
Thanks for your help!

I have just got 2 PPS Sieve WUs that uses the new app.
The app is v1.11. Along with it came the files bluebar.png, numbers.png and primegrid_screensaver_0.9.3_windows_intelx86.exe. Like the first time v1.11 was send out. But this time the priority is Low.
Both WUs are new. pps_sr2sieve_71112_0 and pps_sr2sieve_71177_0. Created yesterday.
In about 3 hours time, I will be abel to give a feedback on the runningtime for v1.11 vs. 1.05 on my host.

Was the v1.11 app only released to Windows boxes? I just received some new work units on my linux box and they were v1.05. |

I was just perusing www.primestats.net and saw that I had crunched 129 PPS sieve WUs. It says I found 4,894 factors or almost 38 per WU which is roughly 1 every 5 minutes. I looked at the top users and found their factors/WU ratios similarly high if not higher.
Is this accurate?

Priority seems ok now, consistent with the separate thread about the issue.
A couple of typical WU times on an OC'ed Xeon X3360 (similar to C2 Q9550):
Outcome | Client | CPU time | granted credit
Success | Done | 7705.86 (2h 8' 25.86") | 220.00
Success | Done | 5397.31 (1h 29' 57.31") | 0.00
1.11 takes roughly 30% less time than 1.05 :)
(I'm slightly puzzled about the zero credit though)

Your computer is to fast :)
Have to change 100 min limit. All wu there time is <100 min is mark'd error.
Will change that now :)

How did you adjust the credit system? What is the rule now?
Just a few WUs as example (all with 1.05)

Old Credit = 220
First we change to 185 then we saw that was to high. We lower one more time to 155.
We try to get same credit/hr that we hade on the old app.

well... This seems reasonable if the new app is far faster then the old one...
but I'm still crunching with 1.05 (long queue...) |
|
|
|
|

It appears that while the app is enabled for 64bit computers, the BOINC software doesn't identify Windows Server 2008 x64 as being able to run the psp sieve. I can run psp sieve fine on Vista x64 but not Server 2008 x64(even though they are *almost* identical kernals). Could you add that so I can put those boxes on it? |

You must install 64bit BOINC in order to run 64bit apps.

I'm an idiot. I'm used to the x64 being on top when you go to the page, but if a person uses the dev argument, the X86 is at the top. |

PPS Sieving Update
PPS sieve is still OPEN for crunchers!!! :)
We have reached our initial goal of 100T. With new users joining each week and the upgrade to v1.8.2 of sr2sieve, we've seen a nice speed improvement. :D
The next milestone will be at 300T on our way up to our extended goal of 1P (1000T). Also, a rate goal to strive for is 4T/day. We have currently reached 2T/day so we're already half way there.
You can monitor our current daily rate here: Proth Sieve - WU's per day
Thank you to everyone who has contributed to the sieve. If anyone is interested in sieving PPS, please see the first post in this thread for requirements. If you are interested, please PM me to have the project added to your preferences page.

I'm not really totally sure if its prime grid or even boinc, but on the first second and third look 3 pps-sieves and a cels WU glued my PC to a stillstand.
After stopping pG all was back up again working well. After reducing boinc to 3 cpus of the quad i can use it again even with PG. But it took about 2,5 hours to enter the BM and stop PG.
Even some restarts before did not help at all.
Has anybody else experienced something like that? To me its quite new, only yesterday this abnormal behaviour did start.
My other Quad is unaffected of it. Its just happily crunching the same mix.

Mostly likely you experienced "above normal" priority for an old WU. Please see this thread for more details.

We are monitoring the errors. It's a relatively low occurrence but still a concern.

We'd like to do a PUSH in PPS LLR to get it up to n=346,000 which is Top 5000 level in Chris Caldwell's The Largest Known Primes Database!
However, the sieve is still more important right now. We have reached the 2T/day level but really need to be at the 4T/day level. With this rate, we'd be advancing the sieve at over 100T per month. This would give us still almost a year of sieving but also allow us to push the lower levels of PPS LLR.
Therefore, PPS Sieve is STLL IN NEED of 64 bit sievers. If you are interested, please PM me or Lennart and you'll be added to the project. If you know of anyone who might be interested, please direct them to this thread.
Thank you for your help!

Is this a separate app ("manual") or does it run within BOINC? How much RAM does it need?
I have an "AMD Athlon(tm) 64 X2 Dual Core Processor 4200+" running Kubuntu 64-bit, 2GB of RAM. I'd like to participate; as soon as yoyo OGR finishes (soon).

If there is a need for more sievers and we expect to sieve another 1+ year, implementing results/stats from PPS Sieve to account overview, server status, primestats.net and http://www.primegrid.com/stats_pps_sieve.php may be worth doing...or at least considering.
It may also help to find more PPS sievers.

Primestats.net already has PPS sieve:
PrimeGrid Charts - look for Proth Sieve
Top Users - Proth Sieve
Top Teams - Proth Sieve
The account overview may be a bit more challenging. However, including it in range stats might be a possibility once it's cleaned up a bit.
Thanks for the input.

Sieve input finally finished downloading.
I have some strange CPU usage behavior. 'top' often shows idle time:
Cpu(s): 0.0%us, 0.5%sy, 50.0%ni, 49.5%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st
(ni = nice, low priority; id = idle)
It seems to be constantly switching between 99%ni 0%id and 50%ni 50%id (and very rarely 99%id). However, both apps are constantly in 97%-100% CPU usage, and their CPU time goes up consistently ("one second per second").
Load average also stays above 2.5 (most of the extra 0.5 is probably from top itself).

Has the workunit length increased?
As I have just noticed on the 3 computers that I have running the PPS sieve, that 2 of them are saying that some of them are going to take about 2 hours longer.
And the 3rd one is saying it's going to take 3 hours longer. |

Turned out to be wrong.
Guess it was Boinc being silly, the workunits took the same amount of time.

WU's are still the same size. We are unsure what is happening with estimation. BTW, we'll post if there's a change in WU size although we don't anticipate one any time soon. :)

Hello!
I will help you!
Now, running 3 Machines (12 Cores) on PPS 64bit.
1x Q6600-Ubuntu Linux8.04 64bit
1x Q6700-Ubuntu Linux8.04 64bit
1x Q9550-VistaHomePremium 64bit
If you have questions about my Hardware and 64bit Software running on the machines, look at http://computertagebuch.over-blog.net/
(I only speak German, my english is no good)
I hope i become Credits for PPS ;-)

Tim, my english is not good.
When you have a question to upgrade your Computer, look at this link.
http://computertagebuch.over-blog.net/
It is writen in german, but much pictures how you can upgrade.
There are prices and adresses of shops you can Hardware buy when you have no much money.

Hey troops!
Sounds like it really is easy to do. John pinged me with instructions. I've given it a go on my 64 bit linux machine. I am just waiting for his PM saying I'm banned because I FUBARed the whole DC system. (I don't care I'm purely AC.)
Absent that have a punt. Especially if it means you get to run 64 bit Linux on your multicore machine alongside a well known commercial OS (think wubi). It really is an eyeopener.
Cheers!

We are making good progress towards our goal of 4T/day. As you can see here, Proth Sieve - WU's per day, we have been averaging over 2T/day for almost a month now.
However, PPS Sieve is STLL IN NEED of 64 bit sievers. If you are interested, please PM me or Lennart and you'll be added to the project. If you know of anyone who might be interested, please direct them to this thread.
For additional information and requirements, see the first post in this thread. Also, for those running 32 bit OS's on their 64 bit machines, read about the Wubi installer in first post.
Thank you for your help! Please spread the word. :)

Rytis, yes I've done it.
file download from http://www.primegrid.com.nyud.net/download/pps_sr2sieve_20080710.sieveinput does not work,
I've tried it also with kget.
but i could download the file with kget from http://www.primegrid.com/download/pps_sr2sieve_20080710.sieveinput
The result is running now. Reached round 8% within 16 mins.

It is possible that your provider is blocking nyud.net domain. It was a test to use it to mirror big files, but we have reverted and newly inserted work will use primegrid.com for downloads.

I think its not the problem, I've tried an other proxy via vpn, so my provider does not see my destination.
there I also got the error message
Your request for http://www.nyud.net/ could not be fulfilled, because the domain name www.nyud.net could not be resolved.

Hi.
Recently I was hit with a couple of compute errors, all of them "out of memory error". Example. I think these started to occur when I joined GPUGrid, and had their WUs occasionally error out with "out of memory" too. I didn't think these are related, however, could they be?
BR,

I don't know if this is relevant or the proper place to post, but here goes anyhow: I have sieved k=225 to 1199, n=520000 to 540000 up to 5.4*10^12, using fermfact.exe. & k=1001 to 1199, n=520000 to 540000, up to about 2*10^12, using sr2sieve.exe. I understand that Primegrid is either sieving this range or will be soon. If anyone wants my results files for whatever purposes, I'd be happy to share.

I just startet with this sieve, and found some problems:
Look at this WU.
I get a message telling me:
Factors file not found
But in the file sr2sieve.log I usually get:
Mon Nov 17 20:24:05 2008 WARNING: --pmin=190487000000000 from command line overrides pmin=1000000000 from `input.txt'
So it seems the input.txt is fine:
-rw-r--r-- 1 boinc boinc 394872512 2008-11-17 20:24 input.txt and head -3 input.txt
ABCD 5*2^$a+1 [120049] // Sieved to 1000000000 with srsieve
24
122
tail -3 input.txt
10
48
84
So what is wrong?
BTW I run the psp sieve since some time without any problem...

The warning message you see is just letting you know that the sieve range has a different start value than what's in the sieve file header. We removed that from the PSP sieve. We should probably do the same with the PPS sieve. :)

To all user that sieve PPS on Boinc.
A new sieve file will come in 48 hr's !!
The file is ~250MB
Those who have many computers can download the file on one computer and copy it to all other.
http://www.primegrid.com/download/pps_sr2sieve_20081122.sieveinput
http://www.primegrid.com/download/pps_sr2sieve_20081122.zip
If you download it one time you can copy the file to the other computer.
“(Drive:)\Program Files\BOINC\data\projects\www.primegrid.comâ€
Or
“(Drive:)\Program Files\BOINC\projects\www.primegrid.comâ€
It depend on your version or how you have installed Boinc.

No, leave the old file. Old WU's will use the old sieve file. We'll make another post when all old WU's have been completed. Afterwards, you can delete the old sieve file.
If you delete before then, BOINC will re-download the old file to crunch an old WU.

Hi Stefan
Wow - quite some assembly of kit you have (20 cores!). Sieve work is always required. I suggest you get John to activate the option and get going on it as soon as possible.
As an added bonus, you'll find it's pretty "credit-friendly" and not so intensive on the hardware as well! |

Hi Warped!
Thanks, but If PrimeGrid had a Mac, PS3 and CUDA application I would have some more cores to add...
Actually I'm not here because of the credits, but because I feel that I have to search for those Primes. ;) (And because of the active forum)

Stefan, you'll find that the number of factors you find and consequently elimination of potential work units is still quite high or dense. In other words, by running 64-bit systems on PPS Sieve the benefit to the project is excellent.

Hey,
I used to be one of the people that were, what you call, 'driving with the handbreak active'. So yesterday I decided to just go for it, and I installed Ubuntu, with the link you provided, as dual boot. So far everything is working properly I think.
It's this and this computer.
There are a few odd things though:
1) The specs of the computer (which is one and the same) seem totally different:
Cache 488.28 KB
Cache 6144 KB
but even stranger:
Measured floating point speed 2601.7 million ops/sec
Measured integer speed 5862.76 million ops/sec
on Windows vs
Measured floating point speed 821.52 million ops/sec
Measured integer speed 2186.11 million ops/sec
on Ubuntu.
2) Boinc seems to be performing poorly.. The only task I finished so far was a PPS LLR, which took 11 minutes. From comparing systems I saw that most systems with roughly the same spec take at most five minutes minute for this, but usually not even close to that.
3) The applications don't seem to be checkpointing.
Since I've only ever used Windows I'm a bit lost where to even start looking for the problem.
EDIT: The second PPS LLR finished in 223 seconds, which is more what I should be expecting, right?
Also checkpointing works on PSP Sieve, but not on 321 LLR. |

BOINC gets CPU specs from OS so each OS may give different information (e.i. Win XP, W2K3 x86, W2K8 x64 etc.)
Alse benchmark numbers among BOINC version are not the same, not the same between OSes. This used to be even worse but some effort was made to make them closer.
BOINC doesn't perform poorly.
PSP Sieve is much faster on 64-bit - be it Linux or Win.
Basically, you can't simply compare 64-bit OS with 32-bit OS when 64-bits apps are available.
There will be differences, it's OK.

It has been almost two months since last input sieve update. Workunits done have doubled since then and we have about 1/4 more factors found.
Is it worth updating sive file again?

When the current queue reaches 0, which means we'll be at 400T, a new sieve file will be released. However, we do not expect a significant speed increase.

400T for that many candidates is good work!
I presume a smaller sieve file will also reduce memory consumption - a smaller RSS can only be a good thing overall - might even fit into on-die cache one day - less b/w for downloading it too - but all these are diminishing returns as the number of factors removed slows down.

Until now never seen another post about this issue.
Is it now save to delete pps_sr2sieve_20080710.sieveinput from our local disks without having the chance of download this old one again?

I believe some projects (Einstein for example?) do clean-up of old files from time to time.
Would be nice if it would go without user intervention.

If you delete before then, BOINC will re-download the old file to crunch an old WU.
If you delete the file by hand at any time, no matter what WUs you have, BOINC will re-download it when you restart it. You'd have to edit client_state.xml to remove the relevant <file_info>, or reset the project!
PrimeGrid should be sending file delete requests from the server; users shouldn't need to cleanup old sticky files.

Hwne doing clean-up, I have found some older sieve files still left. Like 400MB
pps_sr2sieve_20080710.sieveinput
which would be nice to delete or smaller ones like
psp_sr2sieve_20071031.sieveinput and psp_sr2sieve_20071031.sieveinput
which I believe are of no use anymore.

Well, 400T is here. Lennart did some testing and the speed increase would be less than 1%. Therefore, we'll evaluate again at 500T. Up to 450T has been inserted

I'm having problems with this Host running the Proth Prime Search Sieve WU's. Up until a few days ago it ran them okay but then I discovered all the Proth WU's on the Box had erred out after just a few seconds I think and ever since I haven't been able to run the Proth Sieve WU's on the Box.
What happens if I try to run them is the Box basically just freezes up to the point I can't do anything with it & have to manually re-boot the computer. It will run the PSP WU's just fine and any other Project just fine but something with the Proth WU's makes it Freeze.
The BOINC Manager says the Proth WU's are running but the Task Manager says their not & is at a 99% Idle State. The Wrappers show in the Task Manager in the Process Window but the .exc's to run them don't.
I can Boot into Linux & run the Proth WU's okay though, it's just in Windows they won't run anymore. I've done the following to try & cure the Problem short of Re-Installing the Windows OS:
1-Reset the Project numerous times
2-Detached & Re-Attached to the Project several times
3-Uninstalled BOINC & Re-Installed it several Times trying different Version of the BOINC Client
4-Uninstalled BOINC, Deleted References to BOINC from the Registry & Formatted the Partition BOINC was on 1 Time
5-Copied a complete Directory from another Box that the Proth Sieve WU's were running okay on to the Box they won't run on < Still Locked the Computer Up
None of the above cured the problem so I'm at a lose why the Box won't run the Proth Sieve WU's anymore, and whats casing the Computer to Lock Up when I do try to run them ... ??? |

I think you've identified the problem. I've had numerous situations where Windows core libraries become corrupted. Not sure how easy it would be, but I would try the following:
* Check a similar machine
* Identify all of the DLLs it loads (in memory virus scanners do this, so there's likely a utility)
* Compare the file checksums to those on the broken box
Given that you run many computers, and hoping that this is just one of the systems and not one you actually use for anything, I would hope that reinstalling wouldn't be as difficult as if it were your desktop machine. |

I managed to get it figured out without Re-Installing Window, which isn't that big a deal to me as I've done it many times before & have it down to a Science :) ... But anyway I gave the Partition that BOINC was installed on it's own Page File System & the Proth WU's started to run like they should again.
Why they ran okay before that & then all of a sudden wouldn't run I have no idea but everything seems to be okay now ... |

I'd like to try this one out as well. It'll be interesting to see how my systems (Athlon 64 3200+ @ 2.2GHz, Athlon 64 3600+ @ 2.4GHz and Core 2 Duo @ 2.66GHz minimum (overclocked to 3.2GHz when not doing LLR task that cause it to overheat!).
I'm running XP64 on all my 64-bit systems (and will have more soon to give to some project(s), but not sure which yet). |

Is there somewhere to see the range progress for PPS Sieve? Unlike the PSP Sieve, I can't seem to find numbers for the amount of T sieved or factors found. My apologies if this is a work in progress. |

You can find factors stats on PrimeStats.net
Perhaps it is safe to asume that WUs done on PirmeStats diveded by 1000 are Ts done.
You can also se daily througput there...
Freshly downloaded WUs show p453262e9, so about 453T if I'm correct.

Badge score: 1*1 + 5*1 + 8*3 + 9*11 + 10*1 + 11*1 + 12*3 = 186 |

Hello, I'd like to take part of it. Is the gcc version an important factor?
I'm currently running a Q8200 with a gentoo 64bit setup (2.33ghz, 8gb ram, 500gb hd) and 4.1.2 gcc (4.2 tree masked on stable). Could you explain why this gcc requirement.
I also run an amdx2 6400 on win xp 64 with 8gb ram, but probably wont run much on this one.
Regards

ATTENTION
We are releasing a new sievefile to PPS sieve on Boinc !!
Filesize ~233Mb
There is about 8K wu in buffer, when they are done the new sievefile will be downloaded by your Boinc client.
You can download it here sievefile and copy it if you have many computer that run PPS sieve.

Adding to Lennart's post...
In order to have the least amount of impact on the server, we kindly ask all Proth Prime Search (Sieve) participants to please download the new sieve file in advance and place it in your BOINC PrimeGrid directory. That way, when the 8K WU's are complete and the new ones for the new sieve file are requested, BOINC will see that you already have the sieve file in your folder and not download it.
This will help prevent a sharp spike in the the bandwidth and server load. We have about 2-3 days until the new WU's are reached. We'd like to spread the load out over these days.
You can download the new sieve file here: pps_sr2sieve_20090322.sieveinput (~233MB)
Thank you.
p.s. If you're not able to do this, that's perfectly fine. The server has shown itself to be very robust and will be able to handle the onslaught! :) We're just taking a precautionary approach.

Will the older sieveinput files disappear on their own? Should we delete them? Or are they still needed?
Thanks,
Pete

Don't delete it.
Boinc server will delete the file when you don't need it more.

So even the 20080710 file may still be needed?

No; I told BOINC server to issue file deletion requests for it, so it should go away on the next connect. Or, if it does not, you may delete it yourself.

Does this PPS Sieve have 27 and 121 removed?
(I suppose I should download it and compare for myself)

No. 27 & 121 is still in the file.
We will not take them out before we get 27121 up to same level as PPS.

Have both windows and linux 64 bit on most of my machines. Would like to be placed on test phase - at least till sieve challenge comes. come to think of it may also be a good time to see how they perform on challenge too.

Good job, the 20080710 has gone, thanks.
I downloaded the new file as requested but I now see that I have gained another one. The three I have are 20081122, 20090321, 20090322
Did I get it wrong when I downloaded it?
Thanks,
Pete.

20081122 is the one before the last one. Keep it at this time.
20090321 can you delete. Will not be used
20090322 is the current one we use now.
