Hello together, regardless that CentOS 7.X already has EOL status, I would recommend, for example, that you always build/compile OpenMPI and the other tools yourself compile OpenMPI and the other tools to one's needs.
It is true that it is more effort, but in the end it pays off, because the distributions are sometimes very behind. I have already thought about providing something like this, how to do it or how to make the whole process available in an automated way, so to speak. If someone would like to help me develop this, I would be very happy. Kind regards from Berlin.... Z.
