PVM Etiquette for instructional workstations
Because PVM starts processes in the background on many hosts, there is a
potential to leave processes running when you leave. This is why in the
past, the CS Lab has not allowed students to run such parallel jobs on the
instructional machines. With your cooperation, we can make sure that this
doesn't happen and doesn't upset other users (and other administrators).
These rules are particularly important if you are using the instructional
machines (such as nova). If you are using your own desk machine, you're
likely to only affect yourself, and on the SP2 you're likely to only affect
other members of your 838 class.
- Please login (open an xterm window) to each host that you'll be using
in your PVM virtual machine. This will allow you to monitor things, and to
clean up before you logout.
- Complete always your PVM session with PVM console command
halt.
- Before leaving, make sure that no pvmd processes are running on any
host that you used. Type
ps ax | grep pvmd
to check it. Even the pvm halt command
sometimes misfires and leaves a pvmd running.
Then kill any pvmd processes.
- It's also a good idea to delete the
/tmp/pvm*
files on all hosts. These files won't affect other users, but they could cause you problems if you use that same node later.
