CPU and GPU simultaneous processing

Post by jonkloske »

Hi,

I don't seem to be able to execute CPU and GPU work units simultaneously. Basically, one of them "wins", completes its work unit, and the other one stalls constantly trying to contact the work unit server. Here's a log showing the problem:

This is unfortunately just an issue caused by server overload. With the massive influx of folders the server infrastructure is having a hard time keeping up.

I don't see anything obviously wrong with your installation. I think you're simply facing the fact that the FAH servers cannot supply enough WUs.

When you successfully connet to an Assignment Server your client will be asking for ONE assignment, either for the CPU or for the GPU. When it successfully downloads, it will start. At that point, the other device, GPU or CPU, will still need an assignment. The client will continue to ask for that second assignment.

Because of the conditions of the server, there's a pretty good chance you won't get one soon so it will look to you like the first device has "won"

Ahh, yeah, that could be it - I gave it half an hour and now it's loaded something for the CPU and they're both going at it now. Thanks!
