Hi all!

A lot of WUs received by my BOINC client are unable to be calculated till the end. BOINC says:

My GPU is 8600GT, and untill now not even one WU was finished well. Why? And how to deal with it?

Sure!

ForceWare version: 177.84 (as nVidia COntrol Panel says :-)).

Somehow your windows system is using too much memory and the application runs out of memory.

It may looks strange, but my machine doing nothing else when it processing PS3GRID WUs. I left my flat for several days, so nobody (may be, spirits?) could use this PC for any need. From another hand, it always shows that about 1.3 Gb of RAM is free.

May be somehow 256 MB of video RAM is not enough?..

May be it's better to stop calculations on my GPU untill I will upgrade it? But I am ready to participate, and my PC often is absolutely free...

Another one case:

http://www.gpugrid.net/result.php?resultid=50240

It takes 5000+ secs and then crashed.

p.s. I thinf to buy GTX260 for PS3GRID computation, but it seems the problem occures on it too sometimes...

Well, now I'm crunching on GTX260. But there is still a fact: 0ne CPU core is totally busy during a PS3GRID WU processing. Someone told somwhere here, in project forums, that should not be so - "CPU is only need to organize work".

Please tell me someone, why Full atom molecular dynamics 6.43 application using CPU so much?

Actually that core is not doing any real work, just polling the GPU app about its status, as I understood.

This issue will be addressed in future BOINC versions, so that we can use those core again for other projects.

Right now you have to cope with that ;-) This project (the GPUGRID part) is bleeding-edge and hence not perfect yet...

I don't succed to crunch ps3grid unit. my pc: Q9550 / 2 Go Of DDR2-1066, Vista 64bits, HD4850 ... I sugest you to rewrite deviceQuery.cu completely and recompile .

PS3GRID won't work for him.

Hi all,
I just joined the project and 2 of the 3 WUs generated a Computation error:
