Dear Richardo, I, too, am interested in finding where HPC SIG conversations are happening. This SIG does not seem to be on the meeting calendar. If it has a separate mailman, I am not aware. I posted to this list with the !HPC as instructed on the wiki: https://wiki.centos.org/SpecialInterestGroup/HPC If there is a more appropriate place to have these conversations, please point me to it. I am excited to becoming involved in the CentOS HPC SIG and helping out where I can.

I was reading the SIG list[1] and did not find this SIG listed. For those leading this SIG, please add into that list so everyone can read more about your activities.

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.
