NAME App::Prun - Provides the prun script as a command line interface to Parallel::ForkManager. VERSION Version 1.04 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. * 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 AUTHOR Jason McCarver SEE ALSO App::Prun::Scaled Parallel::ForkManager Parallel::ForkManager::Scaled REPOSITORY The mercurial repository for this module may be found here: https://bitbucket.org/jmccarv/app-prun clone it: hg clone https://bitbucket.org/jmccarv/app-prun COPYRIGHT AND LICENSE This software is copyright (c) 2016 by Jason McCarver This is free software; you can redistribute it and/or modify it under the same terms as the Perl 5 programming language system itself.
