How to detect which HPC scheduler (Torque, Sun Grid Engine etc) am I using?

Question

I need to run a different script depending on the type of scheduler, which necessitates a reliable way to detect if the scheduler is Torque, SGE or something else. Something like $SHELL telling which shell I am using. or something like name.

I am aware of environmental variables the two systems set, but they don't offer me a reliable or an elegant way - given the commands the env. variables are named similarly or identically.. there needs to several ifs and buts before we can conclude which is it.

Each of these exports a set of environment variables. Look for those to see what scheduler was used to launch your job. Or just read the documentation of your system. — Jeff Hammond, Dec 24 '15 at 03:59

Set an environment variable explicitly in your .bashrc that you can later query.

e.g.

export RUNNING_ON="moms_gpu_cluster5"
export THIS_SYSTEMS_SCHEDULER="SGE"

You won't have to rely on what the sysadmin gives you, or what the scheduler does or doesn't do.

Thanks, I would prefer an automatic method that would help me derive it from the system config, and not rely on user settings. – Pradeep Reddy Raamana Jan 06 '16 at 19:35
