V11 of CUDA MB mod - attempt to restart freezed apps

Raistmer...........

Can I use this build on by one computer that is always freezes on the GPU?  That computer has only one GPU.  Also what is the number_of_GPUs file and do I need it?

Still not.
I adding detection capability to teamed AK_v8 build too. Then it will look for  GPU app too.
Current build has few errors that I catched today (was able to run this app on dual GPU host). WIll post enhanced one soon.

I may have to stop crunching CUDA on this computer.  Today it has not gone more than 1 hour before CUDA freezes up.  CPU's keep on going.  I tried clocking the CPU and memory back to stock speeds earlier today but still it locks up.  I have no more ideas.

Anybody else have any ideas?  Tomorrow I will swap the NVIDIA card with an identical one from another computer and see what happens.  Perhaps it's a hardware problem on the NVIDIA card and this might help to narrow the problem down.

are you using nvidia cuda drivers? (http://www.nvidia.com/object/cuda_get.html) i have 4-th day gpu crunching - no errors or hungs
(but Mark's ap_info & boinc 6.6.17)

I tend to think it's GPU hardware problem indeed.
On my dual GPU host CUDA MB always hangs only on one of boards (there are  8500GT and 9400GT, but only 9400GT freezes). I swapped cards to get 9400GT primary instead 8500GT - freezing continued.
