Topic 195793

Hi,
I'm running 560 Ti with 2048M memory on the board so I have 6 WUs running simultaneously. It takes about 3 hours for 6 WUs to be finished so for 24/7 my calculation is 24/3*6*500=24000 credits for one day.
But I have only about half of this value and from 40 to 60 WUs in pending list.
As I guess after some time the day value has to be close to the calculated but somehow it is not.
Any advice what is the problem ?

Are some units smaller and others bigger than others? If so then not all would fit in your gpu memory and be causing problems.

No - everything seems good. I have only a few WUs in error status for more then month :

You say you're calculating 48

You say you're calculating 48 tasks per day - that would be two and a half pages per day on your 'all tasks' list. I don't see anything like that number - are you sure your throughput is as high as you think? Better to keep an eye on individual performance, rather than a crude average (and subject to external influence) like RAC.

Also you have a lot of

Also you have a lot of pending tasks for which you haven´t received credits, yet.
If this account is ours you can see that you did receive not a lot of credits in the first week of May. In a week or two your RAC should be higher if you run your computer 24/7, because probably >90% of the pending credits will be added to your account.

Thank you for advice. I'll try to check real throughput by acquiring fixed number of WUs and won't report them for say one day.

Yes, I was expecting to get more credits after couple of weeks but it is somehow stabilized.

Here are some benchmarks in

Here are some benchmarks in an other thread
So you should be able to finish 6 WUs in 3 h.

Yes, this topic encouraged me to buy exactly the same card :)
I have slightly differen result - 3h 06 m because I'm using DDR2 motherboard I guess.

No you have a quad core and the GPU in the other thread is paired with a 6-Core CPU. You can run only 4 thread simultaneously. But I´m not sure because nowadays the CUDA-app only uses 20% CPU time.
