Hi all,
is for this project work for GPU? i see that cuda version is in aplications? is working?

It works! Not quite as fast as PPS, but still nice.

My lucky numbers are 121*2^4553899-1 and 3756801695685*2^666669±1

Hi,
It sorta seems to work. But I'm seeing computation errors. See this task and this task.
Both seem to have failed for "Maximum elapsed time exceeded" at 1:43 elapsed. Could someone please bump up the limit?
These were run on a GeForce 9400M on a MacBook Pro. Boinc manager 6.12.11.
Thanks,
Tony

Tony,
The workunit values have been corrected. Unfortunately there were a number of workunits created before the problem was noticed. These will continue to be resent until they find a machine that can run them. It's a pain, but they will eventually all get done.

All my CW sieve cuda workunits have failed so far on my Linux 64 bit system with a NVIDIA GTX260 using the 260.19.21 drivers. see for example this task.
The PPS cuda sieve btw runs great on my system.

Those nVIDIA 260.19.* drivers don't quite work right. Try 256.53. It's faster, too!
I found a posting that nvidia driver v256.X with latest SDK gives the same error as driver v260.19.X with an earlier 3.X SDK. Please take a look at Microcruncher* posting in thread CWPSieve CUDA testing.
Maybe the SDK 2.3 solve this problem.

I'm still seeing these old WUs. ;-(

Since I'm wasting GPU cycles on these, I'm going to pull back from CW for awhile. Folks, please lemme know if and when this gets fixed. Thanks.

I'm still seeing the Cullen/Woodall GPU app listed under applications;
but not available as a selection under PrimeGrid preferences. If it
were available, I'd run some on our tesla2's. -Bruce*
(If you're recommending app.info, do you know that the one
you have in mind works on C2050's? GeniferCuda definitely doesn't.) |

Tried and Cullen/Woodall (sieve) is available. Check Cullen/Woodall and activate "Use NVIDIA GPU".
If you want to crunch with an app_info you can use the thread app_info file as basis...
C2050/2070 or M2050/2070 are Fermi-based DP-cards. GeneferCuda needs DP and should be running. If not, post all relevant info's in the thread Project Staging Area.

Yes, thanks. Looks like selecting both Cullen/Woodall and Proth for
GPU sieving got me 10 Proth tasks and 2 C/W tasks. These two GPU
sieving projects are listed symmetrically under apps; but even with
NVIDIA activated, there's an extended note in "preferences" for
Proth GPU sieving but no mention of GPU sieving for C/W. Perhaps
there'll be an upgraded profile once the Cullen/Woodall GPU sieving
is viewed as stable.
For those of us with ruby badges from PPS Sieving (44.8 million, and
counting), picking up the ruby badge from C/W sieving seems to be a
plausible diversion, pending a subsequent credit comparision. I like
having the GPU sieving available under "plain vanilla" boinc; not having
to worry about correct settings/tuning in a app_info. With c. 200 x86_64
cores running NFS sieving and with 1000 64-bit windows7 ECM jobs
running overnights, both under condor, I have enough to occupy the share
of my attention available for crunching.
Meanwhile, looks like our 32-bit xeons are doing better on LLR's since
I've gotten the condor jobs off --- PPS (239K), Cullen, Woodall and SG.
I'm seeing 1952 credit/task for Cullen LLR and 2559 credit/task for
Woodall LLR (with none of the 32-bit tasks in yet), so the extended runtime
seems plausible, credit-wise.
C2050/2070 or M2050/2070 are Fermi-based DP-cards. GeneferCuda needs DP and should be running. If not, post all relevant info's in the thread Project Staging Area.
Actually, as a math person, I'm not sure I'd be able to explain wanting
to find a generalized Fermat (at least Proths have a small/tiny chance
of giving a Fermat factor); likewise for 123primes. The install script wanted
to open xterms, while I'm using Xming or Xwin32 terms; and oughtn't to
distract the people in PSA from more likely productive inquiries.

Ha-ha!!!
Look at my GCW Stat:
