OSX GPU Panic

CUDA envvar

CUDA_CACHE_DISABLE

0 or 1 (default is 0)
Disables caching (when set to 1) or enables caching (when set to 0) for just-in-time-compilation.
When disabled, no binary code is added to or retrieved from the cache.

CUDA_DEVICE_WAITS_ON_EXCEPTION

Maybe this can be used to avoid panic despite pycuda blase error handling.

0 or 1 (default is 0)
When set to 1, a CUDA application will halt when a device exception occurs,
allowing a debugger to be attached for further debugging.
