[PyCUDA] Quick question about GPU-CUDA

[Andreas Kloeckner]

Peter,

I followed your wiki page to run pycuda/test/python test_driver.py on porter
and got the following error message.
E CompileError: nvcc compilation of /tmp/tmpImcdf6/kernel.cu
failed
E [command: nvcc --cubin -arch sm_52

E 3 errors detected in the compilation of

E
CompileError
I'm wondering if I'm missing anything. Thank you for answering my question.

Something is very strange here. You traceback references both Python 2.7
and 3.5. Any clue why that might be the case? At any given moment, only
one version of Python should be active.

Next, the failure you're observing is nvcc refusing to compile some
source code. Could you try your nvcc in isolation? (e.g. with code from
here [1]) If that still fails, you should fix your CUDA installation and
then retry with PyCUDA.

HTH,
Andraes
