Message 48965 - Posted: 25 May 2011, 11:25:34 UTC

I'm testing a new framework for running our searches, which should make them a bit more reliable and reduce server load. I've sent out a small batch of 1000 (and won't be generating new ones) to see if this works. Let me know if they crunch correctly for you, they should be named 'ps_test_1_X' where X is some number.

I only use my GPU on this project but all computations for that fail immediately.

Regards

edit: I mean the test units ofc, rest is fine ;)

If I understand what are units GPU? améliroration one of the current application?

for now I only get the de_separation ....

They're separation workunits, so they should be CPU/GPU workunits. They aren't for the n-body application.

All erroring out here. NNT for now.

Since I won't become UOTD anyway for my charming posts: Wasn't there a roadmap saying a) get things stable b) tackle the lag if possible c) do the credit x2 thingy?

Hmm.

These are units GPU or CPU?

Both CPU and GPU. The 'separation' workunits can run on either. The n-body workunits can only run on the CPU.

I'm only putting them out in small batches and checking to see if they work. No need to go NNT, as all the 'de_separation_' workunit will still being generated and sent out.

Either way, looks like the 'ps_test_4_X' workunits are crunching and returning results.

That's fine, I'm not sending out very many of these, just a few for testing to make sure they work.

So in preferences should check any CPU and GPU?

Edit : Oupss I had forgotten to remove the file app_info .... to receive these units ...
