ALICE users at PDSF belong to the "alice" NERSC repository and the Principal Investigator (PI) for ALICE computing at NERSC is Jeff Porter.
ALICE users work in the sl53 chos environment. See the Chos page for more information.
PDSF is a Tier 2 site for ALICE and there is one production account for ALICE called alicesgm. It is used to do the production work of running xrootd, running production batch jobs, etc.
For more information on ALICE computing at PDSF see the ALICE@LBNL wiki pages which are maintained by ALICE users. In particular the How to aliroot at PDSF page contains instructions for setting up the ALICE environment on PDSF and running aliroot, the main analysis software used in ALICE.
