Beacon: How do I switch from Intel MPI to another MPI implementation?

If the Intel compilers and programming environment is still desired, you need only to execute:

module swap intel-mpi $otherMPIModule

However, if you wish to completely remove the Intel programming environment in order to use another compiler, then you must remove the mpi module first:
module unload intel-mpi

Then, you can unload the compilers, which will automatically unload the Programming Environment (PE-intel):
module unload intel-compilers

Beacon: I was running my program in an interactive job but it didn’t finish. I received the message: qsub: job ####.beacon-mgt.nics.utk.edu completed. How do I request more time for interactive jobs?

Request more time for interactive jobs by providing a specific number of hours/minutes/seconds using
qsub –I –l walltime=hh:mm:ss

Note that 24 hours is the maximum that can be requested. If you need an extension, send an email to help@nics.utk.edu along with any job ids that need to run for more than 24 hours.
