Step 1:

1. Do look at the article Configuring CentOS 5 as an SMTP Mail Client with sendmail for configuring your Torque Server to become a SMTP Mail Client.

Step 2:

Ensure the Torque Server has this line

1. “set server mail_from = adm”(You can replace adm with another useird of your choice). You may want to take a look at Setting up Torque Server on xCAT 2.x from Linux Toolkit

Step 3:

Finally, to ensure that the batch system can send an email to the user when the job start, end or abort, you have to set 2 options

1. -m switch which define wh information send
2. -M switch on where the information will be send

For example,

# Send notification when job starts.
#PBS -m b
# Send notification when job finishes and aborts.
#PBS -m ea
# Send notification when job starts, finishes and aborts.
#PBS -m bea

A typical submission script will be

#!/bin/bash
#PBS -N jobname
#PBS -j oe
#PBS -V
#PBS -m bea
#PBS -M kittycool@linucluster.wordpress.com
#PBS -l nodes=2:ppn=8

## pre-processing script
cd $PBS_O_WORKDIR
NCPUS=`cat $PBS_NODEFILE | wc -l`
echo $NCPUS
