Frequently Asked Questions (most with answers!)

The output files only get written to when the run completes; to get around this, redirect the output to a file. So the line in the moab script that runs a program looks like this:

mpirun -np $nproc -machinefile $PBS_NODEFILE ./elemental > output.txt

This only redirects the output, not the error messages; if you want both you'd put 2>&1 at the end of the line.

First please check whether it is not already installed. Most software is accessible via the modules system

module avail

will give you a list of most software installed on the system. If you want to search for a package named “XYZ”, the following command will do the trick:

module avail 2>&1 |grep XYZ

You can, of course, replace XYZ with any software package name.
