[Mvapich-discuss] GDR CUDA 11.4 X86_64 RPMs

[Subramoni, Hari]

Hi, Dan.

We are working towards making MVAPICH2 independent of the underlying CUDA libraries. It should be available with one of our future releases.

Due to changes in the way CUDA implements some underlying features RPMs for CUDA 11.2 and lower are not compatible with CUDA 11.3 and higher.

RPMs for MOFED 5.x should work with MOFED 5.4.

Best,
Hari.

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.
Are there any known issues using a MVPICH2-GDR 11.2 with 11.4?
Are there any known issues using a MVPICH2-GDR OFED 5.x vs 5.4?

Thanks,
-Dan
