I am trying to submit a job to a school server (HPC) with

#!/bin/bash #$ -S /bin/bash #$ -cwd #$ -o ./out_$JOB_ID.txt #$ -e ./err_$JOB_ID.txt #$ -notify #$ -pe orte 1 date pwd ################################## RESULT_DIR=~/Results SCRIPT_FILE=sample_job ################################## . /etc/profile . /etc/bashrc module load packages/comsol/4.4 module load packages/matlab/r2012b comsol server matlab "sample_job, exit" -nodesktop -mlnosplash /bin/uname -a mkdir $RESULT_DIR/$name cp *.csv $RESULT_DIR/$name 

The job aborts saying

Sun Jun 8 14:20:21 EDT 2014 COMSOL 4.4 (Build: 150) started listening on port 2036 Use the console command 'close' to exit the program /usr/bin/xterm Xt error: Can't open display: /usr/bin/xterm: DISPLAY is not set Program_did_not_exit_normally Exception: com.comsol.util.exceptions.FlException: Program did not exit normally Messages: Program did not exit normally Stack trace: at com.comsol.mli.application.a.a(Unknown Source) at com.comsol.mli.application.MatlabApplication.doStart(Unknown Source) at com.comsol.util.application.ComsolApplication.doStart(Unknown Source) at com.comsol.util.application.ComsolApplication.doRun(Unknown Source) at com.comsol.bridge.Bridge$2.run(Unknown Source) at java.lang.Thread.run(Unknown Source) ERROR: Could not start COMSOL Application.

What might be the reason and how should I fix it?
