MATLAB singularity with License server enabled
==============================================

At allocated compute node; activate singularity and run MATLAB image 

.. code-block:: console

   $module load singularity
   $singularity run /app/matlab2023bLic.sif
   or
   $singularity run /scratch/matlab2023bLic.sif

This software license is depended on MUIT MATLAB license.


RStudio on Jupyter with The Rocker Project
==========================================

Without complicated setup, we can run container and work on jupyter notebook environment.

How to
******

 On any node:  activate singularity

.. code-block:: console

  $ module load singularity
  $ singularity run /scratch/rocker_rstudio.sif

RStudio Server(outdate)
==============


One time setup
---------------------
Console::

$ TMPDIR=~/rstudio-tmp # your choice
$ mkdir -p $TMPDIR/tmp/rstudio-server
$ uuidgen > $TMPDIR/tmp/rstudio-server/secure-cookie-key
$ chmod 600 $TMPDIR/tmp/rstudio-server/secure-cookie-key
$ mkdir -p $TMPDIR/var/{lib,run}

Run application with Singularity
--------------------------------------
Allocate resource::

        $ salloc -w node_name -t 1:0:0

or
Use browser with remote desktop on exascale web portal::

$ TMPDIR=~/rstudio-tmp && singularity exec    -B $TMPDIR/var/lib:/var/lib/rstudio-server     -B $TMPDIR/var/run:/var/run/rstudio-server     -B $TMPDIR/tmp:/tmp    /app/geospatial_latest.sif   rserver --www-address=$(hostname -I | awk '{print $1}') --server-user=$USER --www-port=8989

Port Modification
