• Parallel MPI jobs can require 2 "bkill" commands issued within 5 seconds
• If a job doesn't respond to the above, execute "bjobs -w" and find the name of the first node in the list.  Then execute "ssh <nodename> pkill --signal 9 -u <yourUserName>".  You may have to type your password.  This will kill all your processes on the head node (typically bkill will take care of processes on any MPI slave nodes)..
• If the above doesn't work do "bkill -r <jobid>" where "jobid" can be seen with the "bjobs" command.  But use this only as a last resort, since it will leave old processes running on the batch nodes.

A High-Priority Interactive Session (When You Have Beam)

NOTE: This is only permitted for the experiment that currently has beam.  You can get an interactive session using one of the nodes in psnehhiprioq/psfehhiprioq by executing the following from a psana node:  

bsub -q psnehhiprioq -n 16 -Is /bin/tcsh

(or use, psfehhiprioq if you are doing an experiment in the far-experimental-hall, and use /bin/bash if you use bash as your unix shell). Note that the above option is "Is" (capital-eye-esss) not "ls" (ell-ess).

One caveat: X11 graphics don't work in this mode (e.g. matplotlib).  To get X11 graphics, do the above command (to reserve the node), then "ssh psanaXXXX" (from pslogin or psana) on another window.
