Thanks for your reply. I will try the second solution.

BTW I've just checked.

6.5 is going to be the next release. The stable one is 6.4. now. You could ask some of the devs to send you the subprocess part of the source code to include it into your source.

Do you have NCL 6.5.? This function is only available there. 

You can still use the "old" method that exploits Python. It works pretty well and you don't necessarily need to have a NCL "driver" script.

That's how I've modified task_parallelism_2.py

def launchTask(script):
    task = subprocess.Popen("ncl " + script, shell=True, executable="/bin/bash") 
    return task

and then simply launch it from bash as 

python task_parallelism.py plot_pres_t2m_winds10m.ncl plot_gph_t_850.ncl


BTW to the devs, the link https://www.ncl.ucar.edu/Document/Functions/Built-in/subprocess.shtml is broken.

Dear NCL users,
I am trying to build a parallel task using
https://www.ncl.ucar.edu/Applications/task_parallelism.shtml. But I
receive the following error.
fatal: Undefined identifier: (subprocess) is undefined, can't continue.
Should I load any library for that?
Best regards,
