5. Command Line Arguments

Multiprocessing Script with Arguments

We can modify the parallel script to accept the number of cores as a command line argument.

We will use the value of cpus-per-task that we request from Slurm to pass it as an argument to the python script and use that value as the number of cores in parallel. That way we only need to set the cpus-per-task in #SBATCH line and use the value stored in the Slurm environment variable.

The modified python script, 3_investment-parallel-args.py, accepts one argument, the number of cores to use for parallel map call.

Look at the slurm file called 3_investment-parallel-args.slurm and edit it to include your email address.
