[Mvapich-discuss] GDR CUDA 11.4 X86_64 RPMs

[Pou, Dan]

We are just using the RHEL8 GCC GDR binaries. I think we prefer 8.1 GCC.
We always try to support the latest public releases of CUDA, and prefer
to have both Slurm and non-Slurm/PBS versions. I think we expect
customers to have moved to OFED 5.1+.

Thank you for the quick responses. I wish I was able to make it easier
to support CCE bindings for MVAPICH2, but the GNU Libtool patches are a
challenge, especially in regard to the Fortran frontend.

Cheers,
-Dan

>>I was curious about the sensitivity for MVAPICH2-GDR to MLNX OFED and CUDA versions. I know that the base open source MVAPICH2 made efforts to reduce dependence on particular versions of OFED. I also see that there is only DT_NEEDED on libcudart.so.11.0 and libcuda.so.1, since it looks like Nvidia doesn't has not incremented any symbol versions.
