DESCRIPTION
prun allows you to utilize multiple CPUs for some workloads from the
shell more easily.
prun takes a list of commands (stdin and/or from file(s)) and run the
commands in parallel.
prun is a CLI front end to Parallel::ForkManager. It runs commands in
parallel up to a maximum number of processes at once.
* prun --help
* Parallel::ForkManager
EXAMPLES
There are also examples available from the command line --help.
Run tkprof against all .trc files in the current directory, run 32 of
them at a time.
for F in *.trc; do echo "tkprof $F ${F%trc}txt"; done | prun -p 32
Run all commands in a file (command_file), one line at a time. Run the
default number of processes in parallel ($def_processes). Ignore any
failed processes, but do report to STDOUT any that fail.
prun -r command_file
Test with the dummy_load script included in the contrib/ directory of
this distribution:
for F in `seq 1 100`; do echo "contrib/dummy_load"; done | prun
