Fix segfaults on >8 GPU systems #23

Closed grische closed 4 years ago

grische commented 4 years ago

If a system has more than 8 GPUs, the program segfaults on some of the tests without showing an obvious problem.

This PR adds an early exit for such a scenario to avoid random segfaults. It also increases the limit to a more reasonable number for current systems. The impact on the memory footprint should be minimal.

Cool, I want a system with more than 8 GPUs per host, too :) Thank you for the fix!

Thanks for the offer, I appreciate it but cannot accept this and have access to HPC machines :) Let's get your PR merged now, as soon as CI passes. We just have some more jobs queued up in Travis right now, will revisit this later today.
