Should i have something besides boinc 7.0.25 and 301.42 drivers to get cuda 4.2 tasks

I have the same problem ^^ Hope somebody tells us if we need to reattach or something ^^ (an nooo i tried short/standart units and it worked on a fermi card, only not on the 285gtx)

I must wait until a WU is finished AND im in the room where the machine is, then i will try a reattach, could need a few days :)

Detach/reattach wouldn't help. My understanding is they are only giving cuda42 to compute capability 2 or higher cards. The gtx285 is only a compute capability of 1.3

BOINC blog

WinXP32, BOINC 7.0.25, GTX480, GTX295 301.42

I am running the 4.2 app on my 480 and 295 (same box) and the MJHARVEY WUs are at 99% utilization!

I don't have accurate runtime estimates as the 480 is 2x as fast as the 295 so my numbers are all over the place :-) but I will do a comparison to the 3.1 WUs once I have completed some of the 4.2 WUs.

No re-attach was necessary.


Win7 x64, BOINC 7.0.25, GTX680 301.42
Now running an 78-IBUCH_mutTRYP at 95% utilization WOOT. Uses a full CPU core but I'm good with that :-)

Hi, All Tasks CUDA 4.2 give me error on my Ubuntu 12.04 GTX 295 driver 302.17.

The tasks are CUDA 4.2 only for KEPLER or FERMI...?

My first completed 4.2 on GTX680 is a NATHAN_RPS on Win7 x64 = 13,945.16!

670 rig:

MJH long run 5%@ 15 minutes.

EDIT: using 92-94 GPU (non-HT rig) with a 67% Power draw according to Precision.

With a 170W spec from NVIDIA, this puts the card at 114W (not read from wall)

EDIT 2x:

Interestingly, my 680 is running a MJH long as well, and is getting about the same utilization (HT rig) but with 87% draw?

Oh wow i got my first cuda 42 app on my 285gtx without reattach. :) will see how good it works.

Eight CUDA 4.2 long apps completed. Zero errors so far on my gtx570's. Seem to be 30-40% faster than like pointed CUDA 3.1 work done previously. I made no changes since updating drivers to 301.42. They just started showing up.
So far I gotta say that I'm loving them!

On my laptop's GT 630M a CUDA4.2 NATHAN_RPS ran 93% faster than the CUDA3.1 (122252 sec vs 236314 sec). This way it could even catch the 48h bonus. :) That's really amazing! Could it be that the lesser cards gain more than the high end ones?

My 570s appear to gain more than my 580s so CUDA 4.2 might help the lesser cards the most.

Thx - Paul

Note: Please don't use driver version 295 or 296! Recommended versions are 266 - 285.

Any news on the shorter openCL WU's? Have they become stable and/or available?

OpenCL? This is all CUDA.

PPD really rocks!!! I think within a couple of days we will have much more defectors from primegrid or something like this. Strengthen your servers)

OpenCL? This is all CUDA.

Several versions being assigned in both Long and short. Cuda (non openCL) is 3.1 and lower. It will show in boinc manager. OpenCL 4.2 work unit is not the same.
CUDA all true. Programming different, I would suppose.
:)

Been running the updated driver for a couple of weeks and 3.1 tasks (long) have been running ok.

Now had 6 failures and 2 completed.

My crunchers will be going offline whilst I jet off for a family holiday. Will see how things run when I get back.

Back off me hols :)

Returned both my cards to stock speeds and ran 2 short WU's as a test and both completed. Now running long WU's and both seem quite happy.

When we were in Thailand I was nearly tempted to buy a GTX560 to add to my collection - they were quite a bit cheaper out there than in the UK.

OpenCL 4.2 work unit is not the same.

4.2 is the CUDA version. This has nothing to do with OpenCL.
