After extended hardware and software work, sequoia is now open with 824 total compute cores.
All jobs running or queued at the time of the outage were purged to accommodate major version upgrades of the operating system and of PBS. Users will need to log in and resubmit all jobs.
Check http://mcsr.blog.olemiss.edu/ for further information about sequoia post-upgrade.
