John,
Thanks, we will get started on generating this RPM shortly.

Hi Nat,
we are using: MLNX_OFED_LINUX-5.5-1.0.3.2-ubuntu20.04-x86_64
Thanks,
John

Hi John,
Can you tell us the ofed version on your system?
Thanks,

HI Nat,
We have been struggling to get the RPM to work for us -- we've been working on it for about a week. We are using this RPM:
http://mvapich.cse.ohio-state.edu/download/mvapich/gdr/2.3.6/mofed5.4/mvapich2-gdr-cuda11.3.mofed5.4.gnu8.4.1-2.3.6-1.el8.x86_64.rpm
If you could build us a custom RPM for our system, that would be very helpful.
We're running Ubuntu 20.04 kernel 5.4.0-92-generic
GCC version is: gcc (Ubuntu 9.3.0-17ubuntu1~20.04) 9.3.0
CUDA version is CUDA 11.4
CUDA driver: 470.82.01
Please let me know if there is any other information that you need.
Thanks,
John

Hi John,
You should be able to use the RPMs on Ubuntu by converting them with alien. Regarding the CUDA and compiler versioning, you will want to make sure CUDA is an exact match, but the compiler should only need to be the same major version. You will also want to make sure that you match the mofed major version as well, though we recommend matching the exact version if possible. Please take a look at the download page and see if any of the RPMs there match your needs. Otherwise, we would be happy to generate a custom RPM based on your system specifications.
Thanks,
Nat

Hi DK,
Do the CUDA and GCC versions on our system need to match the RPM exactly? We are running on Ubuntu, and there is no GCC 8.4.1 on Ubuntu.
Thank you,
John

Hi,
Thanks for your note. For GPU support with MVAPICH2, it is strongly recommended to use the MVAPICH2-GDR package. This package supports many features related to GPUs and delivers the best performance and scalability on GPU clusters. Please use a suitable RPM package from the MVAPICH2-GDR download page for your system. Please refer to the corresponding user guide also. The MVAPICH2-GDR package can also be installed through Spack. Let us know if you experience any issues in using the MVAPICH2-GDR package on your GPU cluster.
Thanks,
DK

Hello,
We have been struggling to get MVAPICH2 to work with cuda-aware support and RDMA. We have compiled MVAPICH2 from source, with the --enable-cuda option, but when we run the osu_bibw bandwidth test using Device to Device communication, we get a segmentation fault.
Below is the output from osu_bibw using MVAPICH2:
MVAPICH2-2.3.6 Parameters

1048576 236772.67
2097152 333635.13

Can GDR support be obtained by compiling from source like we are trying to do or do we have to use an RPM? We export MV2_USE_CUDA=1. Any recommendations would be greatly appreciated.
Thanks,
John
