The branch msieve-lacuda-nfsathome-cuda11.5 should be fine in CUDA 10.1. The branches msieve-lacuda-nfsathome and try_openmp require newer versions of CUDA due to changes in cub and thrust.

That error is referring to line 1062 of gnfs/poly/stage1/stage1_sieve_gpu.c

You must have the files stage1_core.ptx and lanczos_kernel.ptx in the same directory in which you are running msieve as well as sort_engine.so and spmv_engine.so in the cub subdirectory.

That should be just a matter of having all the appropriate files in the right place including the *.ptx and cub/*.so files, and passing the option "-g 0" to YAFU's LA msieve command.

What version of the CUDA toolkit are you using? If 11.5 or prior, use the msieve-lacuda-nfsathome branch. If 11.6 or later, use the update_cub branch.
