V10/11 of modified SETI MB CUDA + opt AP package for full multi-GPU+CPU use

<< < (11/80) > >>

YukonTrooper:
My WU's are going very slllooowwww.  They take days like this and I haven't seen any CUDA or AK WU's forever.  Any ideas?

Vager:
Will the GPU_CPU combo team work on Vista with mutliple profiles running? It seems that whenever I load up my profile and than while my profile is running with BOINC in the background I switch to another profile, the CUDA app freezes and stops running. I wasn't really sure what was happening, but with V8 of the mod, BOINC would just error out saying it couldn't detect the GPU anymore. Now with V10 every single WU crashes with a Compute error.

Here's a V10 error : which only happens when BOINC is running on a simultaneous account running in the background

I'm making an assumption that CUDA does not work when you have multiple profiles logged in to the computer? Has anyone else tried this.

I first started to notice my problem when and I posted here . I just only realized now after installing V10 that the mutilple users may be the reason. 

Thanks

Probably only active user profile can interact with GPU.

How about if I install the program in Protected mode? Will this allow BOINC to run while there is no one logged in and still use the GPU with CUDA?
