Hello, I have a, hopefully, simple question regarding OFED on Linux systems. On our cluster we are using OFED v4.1* and we would like to upgrade to a later version. We have a lot of applications build with OpenMPI and Intel MPI. In the case of OpenMPI we have a lot of applications build OpenMPI v3* – that is build with the --with-verbs option.
I have experimented with OFED 5.1, but find that our legacy OpenMPI applications complaint about an undefined protocol. A new compile based on OpenMPI v4 with the option --with-ucx works okay, but that is by the by. The situation with Intel is even worse – the processes start, but run forever or at least until I kill the job.
When we install OFED v5.1, is there a special option that we can specify to enable our legacy OpenMPI applications to work or do we need to download/install the an LTS version of OFED? Please could someone advise me what to do.
Regards, David
