Hi Luc, sorry for not seeing this earlier - I'm not sure what the exact issue is, but given the discrepancy between the toolkit (nvcc 10.1.243) and driver (12.1), I would suggest to update the toolkit.
I'm testing using a GTX 1080 before release, so I know there should be no issues with that card (see the test in the current dev branch: http://ftp.esrf.fr/pub/scisoft/PyNX/pyvkfft-test/pyvkfft-test-2023-07-28-gtx1080ti_cu/pyvkfft-test.html), though I'm mostly testing with cuda toolkits >=11.7 now.
Hi Vincent. Thanks a bunch ! Installing cuda-nvcc-12-1 solved the problem indeed.
Just in case someone has the same problem, I shall add that it got installed in /usr/local/cuda-12.1, so the older nvcc in /usr/bin needs to be hidden by changing PATH, and LD_LIBRARY_PATH too for good measure.
Thanks again!
Great ! It should also be possible to rely on the cuda toolkit available trough conda (I think it's automatically installed by the pyvkfft conda-forge package).
Here is the relevant output of
test_fft.py
For a GTX 1080 Ti, it should use compute_61 afaiu.
