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 -e -r command_file
