-With the Sun Studio compilers, use the ''-xopenmp=parallel'' option or the safer ''-xopenmp=noopt'' option.
+With the Sun Studio compilers, use the ''-xopenmp=parallel'' option or the safer ''-xopenmp=noopt'' option. See Oracle's [[http://docs.oracle.com/cd/E19205-01/820-7883/820-7883.pdf|documentation]].
 | ''-xopenmp=parallel'' | Enables recognition of OpenMP pragmas. **The minimum optimization level for ''-xopenmp=parallel'' is ''-xO3''**. The compiler changes the optimization from a lower level to ''-xO3'' if necessary, and issues a warning. | Not recommended unless you know what you are doing and really want full speed. |

+=====Job submission=====
+[Courtesy of Sean February]
+The queue name for the M9000 machine is spark. Your job script (see example below) must be located somewhere in ''/scratch/work/yourusername/'' (equivalently ''/export/home/yourusername/m9_scratch/''). Submission should be done normally via the PBS scheduler from the login node:
+<code>
+yourusername@login02:~/m9_scratch $ qsub jobscriptname
+</code>
+Example script:
+<code bash>
+#!/bin/sh
+#PBS -N test
+#PBS -q spark
+#PBS -l select=1:ncpus=10:mpiprocs=10
+#PBS -l place=free
+#PBS -l walltime=01:00:00
+#PBS -o /scratch/work/yourusername/stdout
+#PBS -e /scratch/work/yourusername/stderr
+cd $PBS_O_WORKDIR
+HOME_DIR=/scratch/work/yourusername/
+LOG_NAME=testjob_log
+THIS_JOB=$HOME_DIR$LOG_NAME
+echo "My job starts here" > $THIS_JOB
+date >> $THIS_JOB
+pwd >> $THIS_JOB
+echo $PATH >> $THIS_JOB
+echo `cat $PBS_NODEFILE` >> $THIS_JOB
+date >> $THIS_JOB
+echo "My job ends here" >> $THIS_JOB
