Matlab is currently available for use centrally on the HPC cluster systems system of the University of Iowa. One may use the Matlab environment by loading the appropriate module:

While it is possible to run Matlab interactively, which can be especially useful for prototyping a job, please remember that login nodes are a shared resource and are intended for launching jobs or prototyping smaller versions of jobs you intend to run. It is not advisable to use interactive sessions for long-running, compute-intensive jobs unless one uses a qlogin session to do so.

Utilizing XEON PHI Offloading
Neon has a group of nodes with XEON PHI coprocessor cards. These extra resources can be utilized by the MKL libraries used by MATLAB via offloading.
To submit a MATLAB job that offloads to the XEON PHI coprocessors you must submit your job with the following options:
| Code Block |
|---|
qsub -l phi myscript.job |
Your job must also specify the MKL_MIC_ENABLE environment variable:
| Code Block |
|---|
MKL_MIC_ENABLE=1 //enables offloading |
