If you look at the top500, CentOS is the most popular named distribution. I hypothesize that CentOS is in the majority of the overall market share.

There we had a significant amount of energy around HPC and I would like to see this conversation continue. Today, I sought out the HPC SIG of CentOS. While there is evidence of activity, I have not seen anything more recent than Fall of 2017. Where is everybody? > > > > Everybody is probably only me right now.
