MATLAB is a multi-paradigm numerical computing environment and programming language.
Getting Started
Run module avail
to get a list of all software modules, or module spider
to get a list of available versions of MATLAB.
module spider matlab -------------------------------------------------------------------------------------------------------------------------------- matlab: -------------------------------------------------------------------------------------------------------------------------------- Description: A multi-paradigm numerical computing environment and programming language. Versions: matlab/r2016b matlab/r2017a --------------------------------------------------------------------------------------------------------------------------------
Use module load
to set up your environment, and then run matlab
to start an interactive session.
module load matlab matlab
If you have not configured a remote display MATLAB will start in text-mode, but the MATLAB desktop is also supported.
ssh -X sunetid@rice.stanford.edu module load matlab matlab &
Running MATLAB in Batch Mode
If you have prepared MATLAB code as a program (.m
) file you can run it non-interactively.
matlab -nodesktop < program.m
You can use this method to submit a MATLAB job to a compute node, and you can even include MATLAB code in-line in an sbatch
script.
#!/bin/bash module load matlab matlab -nodesktop << EOF % MATLAB code EOF
Using MDCS
MATLAB Distributed Computing Server is supported, and you can submit jobs using up to 127 workers. To set up the cluster, load the matlab
module, start MATLAB, and run configCluster
. This only needs to be done once.
Once the cluster has been configured, commands like parcluster
should use cluster (rather than local) workers by default. You can get a handle to the cluster using the parcluster
command, submit jobs using batch
(which returns a handle to the job), and query job state and results using State
and fetchOuputs
.
c = parcluster; j = c.batch(@pwd, 1, {}, 'Pool', 4); j.State j.fetchOutputs{:}
For a more detailed walkthrough see Getting Started with Serial and Parallel MATLAB.
Please note that, while multi-node jobs are supported, FarmShare does not have a fast interconnect, so code that requires a lot of communication or synchronization between workers may not fully realize any expected improvement in performance. You may want to restrict your MDCS jobs to a single node, or to 15 (or fewer) workers, when possible.
