Binary Cyclops Challenge - 06-13 March 2015
Announced is a challenge at the 27 prime search project from the 6th till 13th of March.
We will start at 18:00 UTC and crunch till 18:00 UTC one week later.
To take part, you have to activate the following lines in prpclient.ini:
server=27:100:1:prpnet.primegrid.com:12006
(Copied from main thread)
For those of you interested, the March PRPNet challenge will be starting soon. There has been some discussion on the use of LLRCuda and your GPU as well.
Based on what I've seen, we might be in for a bit of a fight for first place and it might be very interesting.

Is there a LLRCuda for Linux floating around anywhere? |
|

|

Well like Brink I am now wondering if there is a 32bit llrcuda.exe out there. Iain?

Well,
I'm in, "balls to the wall" as they say here in Missouri..
I am willing to spawn many more Vultr instances to ensure AtP finds a prime in this challenge. As for getting prpnet set up, (installed) etc., on Vultr, that's beyond my skill set.
Otherwise, I've got 6 cores ready to go for the challenge, and however many instances Golfer has the patience to setup on my account. ;0

I don't think it'll be very difficult to set up PRPNet on the vultr instances. It says I have 3 account signups through referrals, so once whoever those 3 are bill at least $10, then I'll get some account credit to do some crunching :) I'll set 2 cores on PRPNet from my home computer, and one or two from vultr. I used up the $20 credit, as I already had a web server running for the whole month.. So the rest is on my dime.
Edit: Just realized, my home machine has been running PSP. It looks like the current batch won't finish until 12 hours into the challenge, so I'll be late in joining.

I've got five cores on 27 right now.
There's a lot of competition on the 27 port right now.... I still think AtP will win though... a lot of users are downloading chunks of w/u's at a time... I'm just crunching one at a time...
Man, a prime would be nice.. it would be even nicer if it was a GFN!!

I'm not aware of where there are any binaries floating around unfortunately. I'm not even 100% sure where the one that is in the prpnet packages came from originally, I just kept it there.
The source is still available (see links in this thread http://www.mersenneforum.org/showthread.php?t=14608&page=28), so you could have a go at building it ;)

Yeah right... NOT but thanks for the update. I probably should just upgrade to 64 bit anyway. It's just such a pain to get a new OS loaded and all the drivers installed.
I will be late to the party. I have some prpnet sieves running that won't be done until a little after 1:00 - but it's a 7 day event. IF I can get a 64 bit system installed I will be in sooner but who knows.

Just started my 8 fastest cores on this project now. I'll miss the start tomorrow anyway. My 2nd fastest PC I currently estimate will do units around 3 hours, does that sound about right? |

Set up a 1core 768mb vps for the challenge. install was relatively easy..
Around 90 minutes per WU on the VPS.
Around 105 minute per WU on my PC. (i5-2500k@4.4GHz)

I've got a couple of cores on 27 now. Ages ago I did some 27-121 manual sieving so I have a slight affinity for this work.
I looked around in the application repository for Linux llrCUDA, but didn't see one. It isn't part of the standard prpclient distro either. It's getting bad press from Michael G.; I'm just going to let GPUs run Genefer-WR or sieve for the duration.
Best of luck to us all finding that big 27 "mega"!

I have 5 VPS cores running on 27. Seems to be humming right along.
I tried to start another single instance and they rejected it. LOL
So I will stay with 5 single instances. :) |

They have a 5 instance limit, you can open a support ticket to ask them to raise it. There is also a $100/mo. limit you can have them raise. I've had them raise both limits.
I have 3 768MB VPSs running 27, I have 2 cores on my i5-2500k, and I have a 1-core 512MB VPS at a different provider because I already have account credit there, but it's half the speed of Vultr. If any of the referral credit comes through, I'll open up some more instances.
Looking like a close race between ATP and Russia. We are leading by around 20 WUs, but that isn't much. I've got 5 fast cores and 1 slow core in, go ATP!

I hope you're all having a lovely time. It sounds like you are.
:D
I'm in my own little world atm pushing with some LLR + testing OCL GFN.
Nonetheless go AtP :). I wonder if Russia know about Vultr. It's like we have a secret tool. |

Due to some poor planning on my part, my 3770K is tied up finishing off some PSP LLR work for several more hours. I'll throw it into the 27 mix when those finish up. Might be able to scrape together a little more as well. Fair skies here; no "cloud"s in sight :-)

This reminds me of a ruse we ran against the Power Cows a ways back, with fake messages posted about a free cloud computing service during a challenge. Ahhh, the good old days.

A sweet side-effect of AtP Participating in this challenge so much:
We're currently 3rd place (team stat) on the 27 port. Within 2 days we'll be 1st :-)

Deploying multiple more 768MB VPSs.. I want to get in the top 10 for this challenge, apparently I can't do that with 6 cores. Adding another 2-4. It's not taking long to set up, I have a "startup script" set in Vultr that I have it run, all I have to do after that is change master-prpclient file and update and start.
If anyone cares, the script is below:
#!/bin/sh
wget http://uwin.mine.nu/PRPNet/prpclient-5.3.2-linux_64.7z
apt-get -y --force-yes install p7zip-full
7za x prpclient-5.3.2-linux_64.7z
cd prpclient-5.3.2-linux_64
chmod 777 *
rm 2*
rm 4*
rm 6*
rm 8*
rm 12*
rm 16*
rm 18*
./1-single-install-prpclient.sh
Installs it in the /prpclient-5.3.2-linux_64 directory
EDIT: For now, I have 6x 768MB VPSs at Vultr, 1x 512MB VPS at DigitalOcean(half the speed of vultr), and 2x 4.4GHz cores running the challenge.

I've added a core, because I feel left out. |

Think i'll set up some but wait until the sr5 challenge and learn linux. |

Very AWESOME!
I knew a proth prime was way over due for K=27!
I hope it's a GFN!!

Due to Zunewantan's success, I've pulled out of K=27 and hopped over to the 121... It looks like a prime is overdue there in both the +/- forms...
Nice job everyone on getting AtP back to the #1 spot for K=27...

Doesn't look like it'll be easy for me to go up or down in my position.. 9th place will probably be where I stand. Not bad.

Remind me how to work out PSA credit from the PRPnet numbers please - something tells me it's divide it by 10, and then divide that resulting figure by two? Apart from WFS and WSS, where you don't have to do the latter division. |

Divide the PRPNet credit by 20, and that's your BOINC credit. 20:1 PRPNet:Boinc.
For WWWW ports, it's a 10:1 PRPNet:Boinc credit ratio.

Ah, cheers golfer! |
|
|
|
|

... which raises the question in my mind, since the "formula" for credit is basically the same, apart from the 20:1 or 10:1 ratio, why not just "normalize" the PRPnet credit to BOINC credit? Just have PRPnet award 1/20th (or 1/10th) of what it does now, then it would be 1-to-1 and less confusing to newcomers. AH! I'm going to answer my own question, maybe. There's all of that "historical" credit on the PRPnet individual and team standings matrix, and it might not be possible to retroactively normalize those numbers (which would be required to be fair going forward)... especially if the 20(10) ratio has changed over time (no idea).
Just thinking out loud... didn't want to post any of that on the main boards for fear of creating a firestorm... :-)
Anyway, I'm sticking with this challenge for the duration. It would be great if AtP could find a 2nd (and 3rd?) "27" prime. I believe k=27 and 121 are both deeply sieved, so the "odds" of finding a prime on a given test are better than for other "k" with a similar "n" value (at least I think that's how it works!).

I don't know why it's taking so long for Zune's prime to be shown.
The Primegrid admins used to publish (release) the prime for those with faster systems to do the GFN testing. Zune's prime has to be verified by now, but it's not even been submitted to the Top5000 for verification. It's not like they couldn't edit the entry if it was a GFN...
Those K=27 w/u's only took 1.5 hours on my system...
Anyways, fingers crossed that it's a GFN.

IT'S A GFN DIVISOR!!

By the way, I do not know which box discovered a prime number.
Is a record left in PRPNet? |

Yep! I just saw that.. Wasn't expecting to get above you, but I'm not going to complain.. Just an hour and 30 minutes left, you have 15 WUs in progress, I've got thirty-something in progress, lets see how this turns out.. The WUs have gotten bigger, worth more points and taking longer. At the beginning I was getting 280K FFT sizes, a few days ago I was getting 320K FFT sizes.

Challenge is over now -- I managed to beat brink and get 7th place... Now I have 30 VPSs to destroy.
Total Vultr bill for me: $16.11 for challenge instances. Good thing I'll get $10 in referral credit on the first of the month ;)
