What GPU do you use? On my own system (GeForce GTX 1080, compute capability 6.1 & CUDA 10.1) it works without issues.
I know that a GTX 1660 was giving problems running the previous mfaktc-repunit version with the exact same compilation settings as gr-mfaktc, did not find the problem yet. There might be an issue with my compilation setup or the drivers for compute capabilities > 6.1. The same GPU could run mfaktc (https://download.mersenne.ca/mfaktc/...in.cuda100.zip) without issues.



Maybe somebody else could try to compile it for windows and upload the binary here?
I have no idea what the issue could be, since I cannot test it myself on Turing cards.
