This document is for anyone who has to manage sinister. There's not much in here for end users.
Day to day stuff
Sinister picks up its user accounts from the Active Directory. Make the user an AD account if they don't have one already and then add them to the 'sinister-users' group which can be found in the Surface Science container. A cron job runs once per hour and inserts copies of any new user accounts in 'sinister-users' into sinister's local OpenLDAP system. It doesn't do Unix groups other than the personal group yet. Passwords are checked directly with the AD and not stored locally.
The SLURM prologue script makes the local /scratch directories on nodes as needed.
rocks run host compute "command arg1 arg2"
Startup and shutdown
Use the 'apc' script to power nodes on and off. Most also have IPMI. compute-0-13's ipmi controller is at ipmi-0-13.ipmi .
It runs Rocks so online.
Other useful information
The disks on the head node are arranged as a RAID1 and a RAID6. Hobbit keeps an eye on it.
Chunks of /usr/local/shared are synced from the network every day to pick up new versions of compilers.
You can use the web interface to the IPMI cards on the nodes by starting firefox on the head node and pointing it at ipmi-0-X.ipmi . And logging in with the right password, of course.
