[mvapich-discuss] Can't build MVAPICH2 2.3.4 with NVIDIA HPC SDK 20.7 (successor to PGI 20.4, we skipped the 20.5 pre-release)

[Subramoni, Hari]

Hi, Sylvain.

Thanks for reporting the issue to us. We appreciate it.

We have not had a chance to try the NIVIDA HPC SDC 20.7 yet. We will download and install it locally and see if we’re able to reproduce the issue.

Dumb question – as the error message suggests, did you try adding -fPIC to the compilation flags to see if it helps?

Can you try –disable-fortran and see if this or some other issue occurs? Other than that, nothing pops up to my mind right now. I will let you know if we have any suggestions.

Best,
Hari.

I've just installed NVIDIA HPC SDK 20.7 compilers, now that NVIDIA gobbled PGI - trying to make croaks on

Any hint/clue/solution? The same config built/runs OK w/ PGI 20.4, btw.

I get similar errors building OpenMPI 4.0.4 w/ NVIDIA 20.7 and could not build OpenMPI 4.0.4 with PGI 20.4 (different type of errs tho, I have tickets open w/ PGI).
PGI/NVIDIA distribute OpenMPI 3.1.5, so they are slow catching up, while Intel's MPI distribution has been broken for a few years (and support isn't very helpful - besides acknowledging the problem - we have a Mellanox IB fabric on our cluster). Kind of depressing, IMHO.

    Stay sane, safe and healthy, 6+ft away! Cheers,
      Sylvain
