1. SSH tunnel from your workstation using the following command:

   ssh -N -L ${PORT}:${HOSTNAME}:${PORT} ${SINGULARITYENV_USER}@hpc

   and point your web browser to http:https://localhost:${PORT}

2. log in to RStudio Server using the following credentials:

   user: ${SINGULARITYENV_USER}
   password: ${SINGULARITYENV_PASSWORD}

When done using RStudio Server, terminate the job by:

1. Exit the RStudio Session ("power" button in the top right corner of the RStudio window)
2. Issue the following command on the login node:

      scancel -f ${SLURM_JOB_ID}
