The three commands to get started with the Grid Engine are:
- qsub
- qdel
- qstat

qsub is used to submit a job on a grid. qstat is used to see what are the jobs running on a grid, and qdel is used to delete a job from the grid. Here is a quick example:

cat startServer.ksh
#!/bin/ksh

SGETOOLS=/home/sgeadmin/N1GE/bin/sol-amd64
export SGETOOLS

numClients=10


$SGETOOLS/qsub -N client -t 1-$numClients startClient.ksh

This program starts 10 copies of the client program on the grid. The client has access to some environment variables such as: SGE_TASK_ID

> cat startClient.ksh
#!/bin/ksh
host=$( hostname )
echo "Starting client on" $host with ID  $SGE_TASK_ID >> /home/pascal/test1/file$host
proc=0
while [ "$proc" == 0 ]
do
  echo $proc
done

the output of qstat looks like:

> qstat
job-ID  prior   name       user         state submit/start at     queue                          slots ja-task-ID
