Tue Jul 13 10:45:24 CDT 2021

MPICH 3.4.2 should support --without-cuda, too. 3.4.1 does not.

    Hi David,

    The fix probably didn’t go into the 3.4 release. If you could try the 4.0a2 release, `--without-cuda` should work.

    The “—without-cuda" option causes the compile to fail (where without it the compile succeeds)...

    Hi John,

    Could you try configure mpich with `--without-cuda`?

    Right now it picks up cuda, which links libcuda.so into mpiexec.  Is there
    any way to prevent this?

    Thx....John Cary
