Poor man's parallel execution on servers

poor_man_parallel.sh

#!/usr/bin/env bash

set -e

for N in {1..5}
do
  for M in {0.1,1,2,5,10};
  do
    # Replace ./my_prog.py with your program to run it in parallel
    ./my_prog.py -N $N -M $M > output/stdout_N${N}_M${M}.txt &
    echo $!
  done
done

## Run as:
## ./pool_man_parallel.sh > pids
## Then kill recalcitrant processes from `pids` file, if needed.

@harrymvr The PPID of the processes put in background seems to be 1, i.e. the init process:

I am not too keen on running pkill -P 1. <_<

hmmm interesting. Yeah, I would pass on that as well 😆
