NAME

App::Prun - Provides the prun script as a command line interface to Parallel::ForkManager.

VERSION

Version 1.03

SYNOPSYS

    for nr in `seq 1..100`; do echo "echo command #$nr" | prun

    prun command_file_to_run_in_parallel

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.

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
