qsub passing parameters to -N (name) option

Question

I'm submitting a bunch of qsub jobs that take a range of parameter values. I run the following loop to submit these multiple jobs. I pass the specific parameter values to qsub through -v. I would like the jobname to also be a function of these parameters:

#!/bin/bash    
for a in 1 2
do
  for b in 1 2
  do
  echo "a is $a, b is $b"
      qsub -v a=$a,b=$b -N run_$a_$b run_file.sh
  done
done

Where the run_file.sh contains the #PBS commands to run the program. When I submit to the server I see the following output that shows the loop is working correctly:

a is 1, b is 2

But the job name appears only with the last parameter

run_$b (i.e. run_2 for $b=2)

Instead of as

run_$a_$b

How can I get the jobname to include both parameters? I have tried shortening the file name to confirm it's not a length issue. I would like the name to appear with both parameters to keep track of which files are still running without needing to check the output files. Thanks for any help.

Answer 1

Can't really run this script but try: qsub -v a=$a,b=$b -N run_${a}_${b} run_file.sh

hope this is what you were looking for

Answer 2

in run_$a_$b bash consider $a_ as one variable and apparently you do not have a_ defined something like this should work? run_${a}_$b
