  • Interesting. But I'm not seeing any parallelization and it's not immediately obvious how to implement that short of copy-pasting. Let's say I want to launch up to 32 instances of foo simultaneously and up to 8 instances of bar simultaneously, how would I do that? Commented Sep 12, 2020 at 7:42
  • Inside loop as for i in {1..32}; do ...; done where ... is "if" with foo and second one for i in {1..8} with "if" bar function, all process are going background, so it is pseudo parallelization, but works fine Commented Sep 12, 2020 at 9:26
  • Also this can be written as one liner ;) if you want, also... You can do "copy paste" version for shell (here bash) Commented Sep 12, 2020 at 9:35
  • Also as I think it should be possible to run foo and bar loops independent now main loop waiting for finish all background jobs Commented Sep 12, 2020 at 9:45
  • Ah, well, argumentless wait waits for all children. I see. This should superficially work, but doesn't really suit my problem because foo and bar have significantly different (and variable) performance. I'm afraid this won't be too efficient. Commented Sep 12, 2020 at 9:45
