+1, though it seems to overlap a bit with the SciTech SIG, which focuses on packaging scientific software for Fedora/EPEL.
I'd be interested in joining the HPC SIG as maintainer of several packages which are meant to be used on HPC clusters.
Agreed, this would either be a clustered version of the Server SIG or maybe a more Operational Cluster focus to SciTech SIG, or somehow a combination of both.
