Depending on your level of familiarity with the Shared Research Computing Clusters, you may prefer to submit your MATLAB jobs in one of several different ways.

Easiest: Run from your desktop's MATLAB environment

Set Up the MATLAB Parallel Computing Toolbox with the Rice Shared Computing Clusters on your desktop

For Big I/O: Orchestrate Parallel Toolbox jobs from the cluster login nodes

MATLAB Parallel Computing Toolbox on the Shared Computing Clusters

Don't need PCT?

If you have a lot of single node or single thread jobs to run and understand how to use the cluster scheduler, it is less confusing to simply wrap matlab in a job script:

Submitting MATLAB jobs via qsub

Have GPU accelerated MATLAB code?

Running MATLAB on a GPGPU



Task Parallel Application - The same application that runs independently on several nodes, possibly with different input parameters.  There is no communication, shared data, or synchronization points between the nodes.

Data Parallel Application - The same application that runs on several labs simultaneously, with communication, shared data, or synchronization points between the labs.

Lab - A MATLAB worker in a multicore (Data Parallel) job.  One lab is assigned to one worker (core).  Thus, a job with eight labs has eight processor cores allocated to it and will have eight workers each working together as peers.

MDCS - MATLAB Distributed Compute Server.  This is a component of MATLAB that allows our clusters to run MATLAB jobs that exceed the size of a single compute node (multinode parallel jobs).  It also allows jobs to run even if there are not enough toolbox licenses available for a particular toolbox, so long as the university owns at least one license for the particular toolbox. 

PCT - Parallel Computing Toolbox.

MATLAB Task - One segment of a job to be evaluated by a worker.

MATLAB Job - The complete large-scale operation to perform in MATLAB, composed of a set of tasks.

MATLAB Worker - The MATLAB session that performs the task computations.  If a job needs eight processor cores, then it must have eight workers.

Job - Job submitted via the PBS job scheduler (also called PBS Job).
