Dear Users,

We consider a complex job to be any job that requires more than one
executable within a single MPI execution, a job that requires a varying
number of tasks per node or a combination of both. During the Quick Start
Training, we suggested using Heterogeneous Job submission to create a
complex job request. After working with this method for a while, we believe
this is the wrong approach. We now have another recommended method for
working with complex jobs under Slurm.

We have created two scripts in the /contrib area of Jet and Theia. (We
believe these methods will also function well on Gaea, but have only done
limited testing there.) One is called arbitrary.pl which allows for varying
numbers of tasks per node. The other is layout.pl which allows for multiple
executables within a single MPI execution. They are accessible by "module
load contrib sutils".

We have updated the April training slides to have examples of various
situations that a user may encounter. The updated material starts around
slide 34. The new slide deck is available at
(These slides are still under development but are pretty close to final.)

We will have a short (approximately 30 minute) training session on
Wednesday, April 24th at 11AM EDT that just discusses these updates.
Details regarding location and webinar information will follow in the next
few days.  In early- to mid-May we will repeat the entire quick start
training session.
