Parallel worker is a tool to run batch jobs concurrently. It is very similar to GNU parallel but with less functionallity and less complex. You can just specify a command and a argument list. So the commands got an argument injected and run on a single worker.

make

or

make build

Create a argument list e.g.

for i in {1..50}; do echo $i; done > arglist

Use php to "process" each argument in pool with 10 worker

./bin/parallelworker --numworker 10 --args arglist -- php -r "echo '%arg';"

Each job produces an output block with some information

Worker id: <workerId>
Command: php -r echo '50';
