Adding GPU nodes

Hi @adarsh I followed your steps from here - PBS Single exection host run job using cpu include gpu - #2 by adarsh

And its working fine. I can submit a cuda job.
by doing
#PBS -l select=1:ncpus=1:ngpus=1

But now a strange line is coming in all output files -

/var/spool/pbs/mom_priv/jobs/187.b0.SC: line 14: =1: command not found

This has started to appear only after this ngpus resource addition. I restarted pbs service.
Do i need to check something.
