data are available at NERSC in this directory (the equivalent of /reg/d/psdm): /global/project/projectdirs/lcls/gd/psdm/. Set environment variable SIT_PSDM_DATA to this location so psana will be able to locate the data
ssh to cori.nersc.gov (the equivalent of a pslogin node)
information on the cori batch system ("slurm") is here
there are 32 cores on each cori node
to get to the equivalent of a "psana" node you should run an "interactive job" as described here
