Introduction

Most modern desktop machines have considerable computing power, provided by one or more multi-core CPUs. Parallel, the program described on this page, provides a simple way to use this parallelism in the case where just a number of independent programs needs to be run. Parallel has the following features:

• Parallel reads a list of commands from a file,
• it starts as many of these commands as there are CPU cores in the system, and
• as soon as one of the jobs finishes it starts a new command from the list until all jobs are processed.

Figure 1. This is an example of how 12 jobs could be scheduled over 3 cpus.
