This has been fixed as per another thread.


Not on any of my machines????

I've noticed the same. BOINC is estimating cuda sieves to complete in 14 hours, that actually finish in 25 minutes.

Only problem is that the number of workunits in my queue reduces considerably.

A review of the results in the database shows that the problem does not apply to all Kepler GPUs. There's successfully completed WR tasks on Kepler GPUs, although not a lot, and none on a GT 650M. That last part probably isn't that surprising, however.

Could you try one more thing for me? Reboot the laptop, and then try this command without doing anything else on the laptop (especially opening a browser or email client.)

geneferCUDA -q "1234^4194304+1"


Also, does the laptop have any settings (possibly in the BIOS or the Nvidia control panel) that set how much memory is allocated to the GPU? If so, what is that setting?

Thanks,
Mike



FFT error as shown below.

No NVIDIA seetings oddities AFAIK.

Hi,

In work so cannot run it now.

Will post back this evening (CET).

Don't use FF - use Google Chrome

Can you also try:

geneferCUDA -q "502468^1048576+1"


I'm not yet sure what the problem is, but we'll be switching the short tasks from N=524288 to N=1048576 in the next few weeks, so it would be useful to know if the problem will affect the new short tasks.

Thanks!
Mike

I run a GT650M on my laptop with the latest CUDA drivers.

The laptop runs Windows 7 ultimate 64bit with 16 GB of RAM (i.e. quite standard).

Every Genefer (World Record) v1.07 (cuda32_13) task has an error at present.
