If you are getting started with the OSCAR system, here are a few commands to help you out:

-After you login with your account:

To build the environment: lamboot -v hosts.def

You should see a list of nodes boot up

To compile a program: mpiCC source.cpp -o ouput

where output is the name you give your application.

To run a program on all nodes: mpirun N output

To check for any possible resources left hanging on the nodes: ps -ux

To kill a specific process: kill pid

Where pid is the specific process id

Before you logout run the command to stop the environment: lamhalt

Good Luck
