Description
The issue is pretty self-explanatory: I write a simple job based on demo code, I verify my GPU is recognized, and the context is properly initted-- but when I execute the code, the computatin fails with a segfault... I have an intuition that the issue is coming around compilation time for the kernel, but I don't really know.
Any hints to further debug this issue?
