What's wrong? I'll try to restart my machine, but... There are already several tasks of such kind...

Which drivers are you using?
180.84 should fix the "out of memory" error on XP64.

Seems that BOINC 6.5.0 can't make a gpugrid WU run normally while there's one or more lhc@home's WUs being processed...

Don't think so... I also use BOINC 6.5.0 and I'm running GPUGRID and LHC right now. No problems so far...

Me too ...

Two systems ...

Sadly, I can't seem to grab that much work off LHC ... even though I have been trying for ages ... sigh ... my favorite project ...

I guess I best not think about it or I will be getting even more depressed ...

I have made the same experience in the past, so I only crunch LHC on my other boxes without CUDA. Don't know why there are problems, but know that ... :(

Well... You are lucky guy, what else can we say here... :-) Hope that BOINC crew will deal with it...

@Stefan: Do you run Linux? I have no problems with LHC and BOINC on Linux, but many problems on Windows 64 bit.

Actually I use both, Linux and Windows.

The Vista 64 bit host with BOINC 6.5.0 x86_64 is crunching a mix of LHC, GPUGRID and a few other projects without any problems. The same with Linux 64 bit - no problems if I run LHC + GPUGRID. But on the Linux hosts I still use BOINC 6.4.2. Because they are only remote controlled with BOINCview and without monitor and keyboard/mouse I don't update them very often...

I don't think it's a BOINC problem, it's got something to do with the science apps and the graphics driver.

A question to all you guys who have problems with GPu-Gird and LHC: are you watching the LHC graphics? Even once may be enough to trigger the error, if their app doesn't free the vid memory correctly.

In that I love my LHC I don't plan to try ...

However, I will say that I have two machines happily running both LHC and GPU Grid ... LHC work is validating and running to completion normally ... but I do not use the graphics except on rare occasions ...

The screen saver mode kicking on may also be an issue for those that use that ... or allow that ...

Fun times ...

I posted this on the BOINC Dev mailing list:


There are scattered reports that running GPU Grid at the same time as LHC@Home can cause failure of LHC tasks.

For those experiencing this problem we are asking for more input to see if we can discover more about the problem.

Current suspicion is that LHC may not be correctly clear the video memory. Thus if the participant looks at the graphics or the screen saver kicks on there will be an issue.

This may be an issue actually with the BOINC Graphics library interface where it does not do proper garbage collection or state restoration.
