hi,
thanx for replying !
qsub -l nodes=2
is not required since v r not submitting a parallel job. the shell script i submit is as follows:
#!/bin/sh
### Job name
#PBS -N test
### Output files
#PBS -e test.err
#PBS -o test.log
#PBS -q workq
#echo Working directory is $PBS_O_WORKDIR
#cd $PBS_O_WORKDIR
echo Node_File is $PBS_NODEFILE
echo Running on host `hostname`
#This will keep cpu busy for 20 secs
sleep 20
#echo Time is `date`
#echo Directory is `pwd`
#All done
this scrpit when submitted twice ...the second submission is queued ..although second node remains free
( i chked that using ps -ef on second node and
also pbsnodes -a shows it free and node1 as "job-sharing" )
as far as maui is concerned , we have stopped it and instead started pbs scheduler
/opt/pbs/sbin/pbs_sched -c config
(also started the scheduler without -c option , but in vain)
config file :
$clienthost node1
$clienthost node2
