Just wondering is anyone else experiences the following behavior with the boinc mgr. When I place the mgr and all running tasks in "snooze" mode the video driver crashes then recovers almost immediately. This only happens when usingt the snooze feathure. I'm running Geforce version 280.26 with PhysX ver9.10.0514 and I have a EVGA GTX590. I pretty must assume an update in drivers may solve the issue but it may not, just wondering if anyone else has seen or dealt with this previously.

That's probably not a problem with the BOINC client (the manager is not involved anyway), but with the CUDA applications of the different projects, which aren't all thread safe when exiting midway (snooze, suspend).

OK so what does that mean? Updating the Geforce drivers which will update the cuda parts will not resolve this issue? So everyone experiences this issue if it's attributed to projects use of CUDA apps? Oh and thanks for the help.

For the non-thread-safe applications, only downgrading the video drivers would help. Otherwise, you'll have to wait until the projects deploy thread-safe applications.

Ah OK I understand thanks. I don't want to downgrade my drivers just for crunching, my primary system I built for gaming. Crunching is for downtime between gaming sessions.

I just tested this on 285.62 (Stable BOINC) No problem, suspending a tasks or the project.
But I'm running SETI.
The driver calling is a project thing, so the problem may not be with the BOINC client.

Which GPU projects/apps are you running? If it's Seti, and you're running the Stock Cuda apps, just moving over to the Optimised apps will help, (the latest Cuda apps are thread-safe applications.)

(Edit: the reason Fred's hosts don't suffer is because he's running the thread-safe x38g and x41g Cuda apps on his hosts)

I think there is something going on related to the 590.
Om my computer the tasks fall back to the CPU.

Yah that's because I noticed both gpus on my 590 were not being ultilized fully so I chatted with my buddies over at http://www.overclock.net who suggested I add this,http://www.overclock.net/t/827904/how-to-multi-gpus-on-boinc]. This code really works but is it causing error when processing wu?

Ops sorry not used to this forum setup, fixed this should work now.

All my problems were gone, after I disabled the SLI on the 590.

Wow! that must have really hurt the performance on gaming if you do that sort of thing. Was that absolutely necessary?

Yep otherwise things go horribly wrong, but you can switch SLI back on easily.
