I've just noticed that you have reduced the credit for a PPS Sieve work unit from 4534 to 4070 (10% rounded). Is there a reason for this, as I don't see a reduction in the time taken. Or have you too many folk crunching this project, and wish to reduce the numbers? |

GCW sieve credits per WU were also reduced to 327.99 (from 364.43). This is probably an adjustment to the decreasing run times over time. Did anyone check the other sub projects?
At least one project installed a server update, which implemented some really creative ways of granting credits a few months ago, without taking a closer look at the change logs.

SGS and TRP Sieve are the same... PPS LLR, I can't tell. That's having a quick check.
However, I have not noticed any decreasing run times recently, they are the same as last month, the month before, and the month before that, etc... in fact I am getting almost exactly the same run times (+ or - only a few seconds) as when I joined the project in February. |

I haven't seen any noticeable differences in the last few months...

The decrease just occurred and the times are at least as long as before -- what gives?

Confirmed, my run times are identical but credits are reduced!
Seems to be all WUs from 9am UK time for me that are gaining less credits.
____________
My Top 5000 Primes:
110059!+1 is prime! (FPS)
14493618614235*2^666666-1 is prime! (SGS) |

I can confirm the same as others state - same run times lower credit given (4,070 from 4,523). RACs are noticeably falling. |
|
|
|
|
|
The reduction is precisely 10%. My run times haven't changed in the last couple of days, but they are a couple of % better than - let's say - a week ago. |

Gang,
I have double checked my results also and I have a nearly 500 credit reduction for WUs returned after 30 Jun 2011 approx 1200 UTC. This impacts my dual core Intel, my tri core AMD and the Phenom II X6 desktop. Tasks returned on 30 Jun 2011 before this time post the standard 4523 credit for CPU while they now post 4070 credit for the exact same CPUs. There have been no changes in either machine (hardware changes / software updates)
My runtimes are within a few seconds of each other and it appears to be a simple change in credit awarded....
*HOWEVER*
I did notice in the tasks now currently enqueue are showing an estimated time to completion of GREATER THAN 2000 days on the Intel, while similar tasks show the estimated time to completion of 43 days. Regardless of a C2D V2, Phenom II N850 or Phenom II X6 1045T, all return within 24 hrs. The X6 is obviously the fastest at 17.5 hrs, N850 at 21 hrs and the C2D at approx 23 hrs. The X6 is a desktop machine w/ DDR3. The N850 and C2D are laptops with DDR3 and DDR2 respectively.
IF there is anything I can do to help, ****PLEASE**** don't hesitate to ask me.
Tnx,
C.
This has been the normal for me for both Linux laptops.... BOINC 6.10.58 and FC-14 64-bit now for over 3 months. |

4070 is not prime. If this reduction was intended, 4073 would be much better. ;)

Sorry everyone. I'm in the dark on this one as well. The 10% decrease in PPS and GCW sieves does seem arbitrary…we'll just have to wait for Rytis' response. Again, my apologies.

seems back to normal - but would like to hear from Rytis - and would like to have the bad ones corrected!

also verified PPS Sieve back to 4523...
thank you to whoever corrected them...
would be possible, please, to correct the 10% light ones? |

I was able to touch base with Lennart today. Rytis did decrease credit for PPS and GCW (Sieves) by 10%. However, they have been returned to previous levels until further information can be distributed.
The first snafu of "summer hours" is miscommunication. The credit reduction was a bit premature; however, a reduction is coming for PPS (Sieve). Please see this post for more details.

Thank you to our moderators who stepped in on our behalf and thanks to everyone for speaking up.
My credit values have returned as well

thx for the correction
because of the -10% i've planned to stop GPU processing for primegrid and spend all my GPU-power to other projects.
now i will not stop. |

Not only has credit decreased to 4327/wu but my runtimes have increased from 18.25 min to 40.25 min

Possibly the NVIDIA downclock problem but we need more information... driver version, clock rates, etc.

Strange, not here at my machines. What other apps did you running besides PPS Sieve?

My small GT240(GT218) with DotschUX listed also the different credits 4070, 4327 and 4523 for ~4800sec work of one PPS-unit in the last days.
Cullen/Woodall Prime Search (Sieve) seems to be back to normal. The same host listed now 364.43 credits instead of 327.99 for the same ~910sec on june, 30th.

FYI...the Cullen/Woodall Prime Search (Sieve) will not have any decrease in credit. It is not affected by the switch from sr2sieve to tpsieve. The initial 10% decrease was a mistake.

Is there any easy way to correct the DataBase for CW sieve?

I'm getting 4127 for the past few days. Runtimes are consistent with what they've been since I started in Jan 2011, but the estimated time provided with the WU is WAY OUT OF WHACK *AND* it's making the machine run a LOT hotter than normal (> 6C for the last 8 days of work)
My 'Cobblestones' hasn't changed... nothing in the machine has changed regarding BOINC. no glibc, etc or other changes which would impact task runs. FC-14 updates coming in are typical gui-only fixes.... no kernel, .ko, .so or other significant changes.
Can someone please look at the WUs being generated to ensure they are being estimated correctly? The PG server is reporting longer than normal runtimes for Windows users (mostly). My preferences now shows the recent average runtime (or similar wording) to have shown an increase.
Is there an announced project work change? More work per WU w/ less credit announcement ? Is this version of tpsieve up to the task? Are GPUs now the preferred method of working on Primegrid tasks? If GPUs are the preferred, could someone please see about expediting the OpenCL availably for all PG tasks?
My nVidia is running the OpenCL but not the Cuda driver because nVidia does not permit/support Cuda in a laptop GPU coprocessor for the primary video driver. Yes, I have two configs... one nVidia w/ 512MB dedicated RAM in one machine, and an ATI 4200 as the display/HDMI (when HDMI activated) processor w/ a 5000 HD series (with 1GB dedicated memory for the GPU) for the 3-D rendering (which I do none of) OpenCL in the other.
I don't understand but windows-7 professional 64-bit has gotten TERRIBLY slow at both PPS Sieve CPU and ati13ati apps using the existing drivers. Windows now takes 50 % longer to turn a task around (CPU) and 2x longer for ati13ati than in March-April. Is this PG unique? The PPS Sieve WUs are coming in under windows-7 at 400+. No other apps have slowed down. They have gotten faster if anything thanks to the fixed by MS.
The current status makes me think my machines are 'running sideways' Yet everything else... Even code I've written/compiled last fall is running the same (or faster). I know tpsieve, sr1sieve and the whole family of programs Geoff has done well. He's well respected in the mathematics community for making things run faster / more efficiently. He's got one unique, great mind when it comes to putting theoretical mathematics (what prime number theory is) into practice as a computer program.
It's coming to the point where giving PG a laptop with a GPU in it is becoming no longer viable. Is this PG's choice or an unknown problem now showing itself so it can be fixed? In contrast... I know an ATI 6900 card in a Windows machine (which can return sieves in ~20 minutes elapsed). it Does have all the current ATI/OpenCL drivers for certain (i have them here for win, but not quite working on linux YET). My Team's participation in PG has dwindled to only 4 from the once 10-15+ we've had a few months ago. Two top producers have moved to other projects. The last 'mainstay' left just the other day. He has a pharm of AMD and NV GPUs.
Help please?
