Killing jobs cleanly
•MPI jobs will hang for a variety of reasons or not behave the way they should e.g take too long or give absurd results…
•In such cases they should be terminated.
•This should be done in such a way as to ensure a clean environment for subsequent jobs.
•Scali MPI:
•  scakill  -f nodes  -s qcd
•Dangers: in Scali all jobs matching the given string are killed!
