It is a good point, we can wait. The problem is when you have a lot of computers and no budget to be used in OS. As has been reported, you can use RHEL in the front servers, and Fedora in the cluster itself. The problem is to have a real software compability. When having a lot of users, working with their own programs, you have to be sure everything is going to work. However they are going to compile the programs "with poor knowledge" in the front servers, and they will have problems when using the binaries in the Fedora systems... > > Could we list pros/cons about using CentOS stream in a > > computational Center? > > Pro: will always be ahead of RHEL, with all new bugs and features > > Con:will always be ahead of RHEL, with all new bugs and features ;-) > > > > Are we going to see CentOS stream in the top500 list? > > I am willing to bet a case of Estrella Damm on "Never".
