I don't know about this timeout. As I said we didn't really had time nor
the resources to investigate the crashes. But I've definitely seen a
machine freeze when launching a binary containing CUDA code.

AFAIK, the multi GPU Tesla boxes contain up to 4 Tesla processors, but
are hooked to the controlling server with only 1 PCIe link, right? Does
this spell like "bottleneck" to anyone?
Sure, moving data between host memory and GPU memory is not what you do
the most often, but still.
