Running GULP on Invicta and Napier

GULP v4.0 has been compiled using the default environment. An environment module has been created which can be invoked as follows.

A sample job script for GULP on Invicta might look as follows, change to "ptile=24" for Napier.

This can be submitted to the LSF queue using the bsub command.
