IF you want to run batches of jobs on a single node, but need multiple runs (e.g. 6 core processor, but 20 processes to run), this is a mostly efficient way to achieve this. Not as good as a dedicated system, but close as long as jobs are equal in ru

job_example.sh

 
inc1=0
inc2=0
while [ $inc1 -le 100 ]
do 
 inc1=$(($inc2 + 1))
 inc2=$((inc1 + 5))
 echo $inc1 $inc2
 for i in $(seq $inc1 1 $inc2 )
 do
