I have found compat-openmpi packages for centos 7
https://linuxconfig.org/how-to-install-rpm-bin-package-in-redhat-linux-8
or
https://centos.pkgs.org/7/centos-x86_64/compat-openmpi16-1.6.4-10.7.2.el7.x86_64.rpm.html
However, I need one for redhat 8 or centos 8. Any ideas of where to find packages for compat-openmpi for centos 8 or redhat 8? Also how to do go about installing this package?
