That would be the line

Make sure you have the files stage1_core.ptx and lanczos_kernel.ptx in the same directory in which you are running...

I was just looking at the better scaling of msieve's block Lanczos using 3rd gen NVLink. On both current CPU clusters and 2nd gen NVLink connecting V100s, msieve's runtime consistently scales as...

If that command didn't exit with an error message, then you weren't using an msieve binary compiled with MPI support. MPI is a compile-time option.
