Current Projects

This is the list we will work from in addition to service requests.

Some important procedural pages:

Please update specific projects at their own page.

Post-shutdown, here are things that need fixed, updated, etc.:

  • Al-salam: PDU was powered off when we got to the basement - nodes 1-4 and 9-12 are connected to the PDU so they were powered down. Unsure when 9-12 were connected to the PDU; 1-4 were the only al-salam nodes connected this summer.
  • Sudo for whedon only pwd required
  • Hard to force shutdown on hopper
  • Babbage slow to shut down, had to reboot (even in the shell, shutdown -h now only rebooted it)
  • Mounting FS in smiley, had to run: mount --source=/dev/vmdata/eccs-home-disk/ --target=/smiley-eccs-home-disk
  • Pollock needed manual ifup
  • ganglia monitoring comes back up on some nodes (definitely on head nodes) but needs to be started on compute nodes
  • Are sysadmin accounts backing up to anywhere?
  • How much power are we drawing at max from everything? (PDU, burnout, etc.)
