Wait what: `parallel` is a Perl script!? [1] I would have thought it's black magic with assembler optimisations for MIPS and special considerations for HP-UX..

Wait what: `parallel` is a Perl script!? [1] I would have thought it's black magic with assembler optimisations for MIPS and special considerations for HP-UX... This is such a lovely and interesting writeup, it's wonderful that people take their time to share so generously! [1] : an 11k loc petal script, you can read along here: https://github.com/gitGNU/gnu_parallel/blob/master/src/parallel https://github.com/gitGNU/gnu_parallel/blob/master/src/paral...

assembly optimizations for starting processes?
- remram 4y ago
  Maybe for reading the input, splitting it, and assembling the possibly-very-long argument lists passed to the processes.

    Those things are all very fast compared to starting a process
    - remram 4y ago
      Command lines can be very long, so you can potentially read a million lines between executing processes.
