Are there special considerations that should be made, or other best pratices to observe, when using several GPUs?
I have a computer with a GTX260 and a GTX295.
If I run kernels on all three of them, sooner, rather then later, I get a segfault, and the graphics freeze. One needs to ssh in and reboot get back up and running.
I can run on each card independently.
The general pattern is that the segfault appears to occur on the second card that finishes a kernel. Sometimes it works for several kernel executions, but mostly the problem shows up really quickly.
I’m trying to determine the cause of this.
