Is anyone running 2 WUs anymore?

[Bryan]

Just curious, has anyone tried this for other GPU projects? Running Collatz my GUI isn't really slowed down at all (even though the GPU is @ 100%). Wondering if that might help in the daily take.

Don't run 2 wu on Collatz because on that project BOINC won't ask for new tasks!!!!! You should elevate the priority though with the p3 b-1 cmdline option.

I'm running 2 wu on PG on the Cudas ... there is debate whether it actually helps. Since I'm new to the Cuda/PG game I haven't tried going w/ just 1 wu. I'm VERY content with how things are working currently.

GPUGrid definitely is improved running 2 wu.

What is the minimum CPU allocation you can use without impacting the speed of the GPU? I am currently using two tasks, each using .5 CPU.

I don't have a real answer but like you I'm allocating .5 CPU per wu on the I7. The real reason there is to keep the memory hog Constellation from running more than 6 threads.

When they 1st came out with the new app it was almost a requirement to allocate that much(or more) but since the .62 app came out I imagine that is much higher than it needs to be.

I don't allocate any CPUs to feed the GPUs since 0.62. Wouldn't make sense running 4 WUs per GPU that way. I haven't cross checked my crunch times though. But they seem to be fine. BoincTasks says about 1-2 sec. CPU time per GPU minute.

Wanted to get in on the double points, but I think I screwed up when creating a new App_info.xml file. Can anyone spot my screw up?

That code had a few typos all fixed.

Edit: If you still have issues with the above code then you could always try arkyns code ---> http://www.arkayn.us/forum/index.php...a=view;down=32

Thanks for the info! Seems to be running now.
