Peter,

Are you using a 32 bit Linux? GPUGrid supports only 64 bit Linux.

Voting for Epoch 2 has begun. http://einsteinium.org/nominations/

Time to vote for GPUGrid

Done.

But yes, just try to put a search on the forum on March 21 and today's date. Constant is rising average error notification here on the forums..

Uh oh, March 21 was also the birthday of a friend of mine. Shame on her for breaking GPUGrid!

No, no.
You got it all wrong!
The tall greys just told me that the vernal equinox is to blame for that.

STOP PRESS: Zoltan passes 3,000,000,000 Have a beer on me

:)

Thanks!

What a coincidence, I'm not usually drink :), but today I had a pear cider, then I got here.

My new badge is:

Arginine


This milestone is a very nice present for my forthcoming 45th birthday (13th April).

That reminds me my favorite poem.
7) Message boards : Number crunching : Question, which driver version is best? (2014-04-07) (Message 36147)

Hi guys,

Which drivers version is best for crunching GPUGrid WUs, 331.82?

I'm presently using 2x GTX-670.

Thanks in advance.


According to Matt, one of the Admins, in order to run the newest cuda60 tasks:
"Needs to be 334.21 or later
Matt"

Cuda 6.0 tasks are not faster than the Cuda 5.5 tasks, so only the CC5.0 cards need the latest driver.
For the fastest cards (GTX 780, GTX 780 Ti, GTX Titan, GTX Titan Black) it's not recommended to use the latest driver under Windows (especially under Windows XP), as these drivers don't use a full CPU thread to feed the GPU, which reduces their performance.

I would prefer a metric in which the credits per unit of computing were comparable to other BOINC projects that don't use GPU computing.

We all would.
But it's much harder to measure (or to calculate) the actual flops done by a GPU task than a CPU task, because the GPU does many calculations simultaneously. As there is no standard for calculating the actual flops done by a GPU task (and probably there couldn't be such at all), different projects give different amount of credit per GPU time. It makes hard to put different GPU projects in comparison (especially with CPU projects), so the cruncher should not judge the amount of scientific contribution only by the credits given for GPU work. It's like comparing apples to bananas. We are crunching to aid research, not for the credits, right? After all, you couldn't do anything with the credits earned at any project, it's just for comparison between the contribution of the users of a given project, but not for the comparison between different projects. However, the much lager amount of credits earned by a GPU task correctly reflects the computing capability ratio between GPUs (parallel computing) and CPUs.

One more badge left. Think I need to rest first before this epic journey commences.

Congratulations!

Maybe because I'm too tired after working 12 hours today, and driving 130km, this quotation came to my mind:
"Life is a short warm moment, death is a long cold rest" - from Free Four - Pink Floyd (nice fractal images, besides the waving)
Or, this is the way my subconscious want to say: "please, don't rest!" ?

It was 120,000 credit for long runs about a week ago and now rarely see 120,000 credits. Every time I get my rig going well, things change for the worse. 50,000 by 50,000 will take a while to climb the ladder.

You should take account of the running time of the given workunit. Shorter workunits generate less credit, but they do it more often.
However there is a small (~10%) variation in the credit/time ratio of the workunits.
