GNU Parallel is a general parallelizer and makes is easy to run jobs in parallel on the same machine or on multiple machines you have ssh access to. You can even put this parallelization in the Octave script. It will default to 1 process per CPU core and it will make sure the output of two parallel jobs will not be mixed. Is permitted in any medium, provided this notice is preserved.GNU Parallel will not do multithreading, but it will do multiprocessing, which might be enough for you: seq 50000 | parallel my_MC_sim -iteration Verbatim copying and distribution of this entire article (parallel) installation error 'command_editor', 'octave_env' has not been declaredĬopyright © 2022 Free Software Foundation, Inc.

Installing the latest package release (3.1.3) from octave forge did not work, and while I was able to compile Olaf's patch from ( ), I was still not able to get parcellfun to work.Īs I wrote in my comment #3 below, however, I did manage to get things to work using the packages octave-forge-parallel (and octave-forge-struct) for OpenSUSE Leap 15.1.
