Not working with CUDA 10.X and V100 #95

Open TJKlein opened 4 years ago

TJKlein commented 4 years ago

Hi,

I don't get kmcuda running on a V100 (CUDA_ARCH=70) / CUDA 10.0/10.1. It always freezes when running python test.py and while usage.

Here is some output from the test:

Hi @TJKlein what's the native and Python stack trace? Install python3-dbg, then gdb --pid #your pid# and finally bt.

Hi,

I am using Python 3.6 on Ubuntu 16.06. Thanks for looking into it.

Here is the stack trace:
