[Mvapich-discuss] GDR CUDA 11.4 X86_64 RPMs

[Subramoni, Hari]

Hi, Dan.

Please let us know any specific RPMs you would be interested. We can build them for you. We are working on building the ones you'd requested for as we speak.

Unfortunately, we are still rolling out RHEL8 and newer CUDA versions internally. Once that process is complete, we will be adding newer RPMs to our download page.

Thx,
Hari.

Thanks. This is a bummer, as I have a request in for 11.4 RPMs, but it seems unlikely to get them by Monday, which would be the timeline to fit our release schedule.
It would be greatly appreciated if GDR could keep up with latest CUDA minor releases for RHEL8 X86_64 Slurm/PBS, but I understand there are a lot of builds to run. I am surprised that you still seem to have a lot of RHEL7/OFED 4.x support.

Thanks,
-Dan

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.
