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.

Thanks,

I am very happy to see we have a HPC SIG within CentOS project. 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.
