[http://www.gnu.org/software/parallel/ GNU Parallel] is a tool for running many sequential tasks at the same time on one or more nodes. It is useful for running a large number of sequential tasks, especially if they are short or variable duration, as well as when doing a parameter sweep. We will only cover the basic options here, for more advanced usage, please see the [http://www.gnu.org/software/parallel/man.html official documentation]. | [http://www.gnu.org/software/parallel/ GNU Parallel] is a tool for running many sequential tasks at the same time on one or more nodes.

By default, <tt>parallel</tt> will run as many tasks as the number of cores on the node, therefore maximizing resource usage. When a task finishes, a new task will automatically be started by <tt>parallel</tt>. | By default, <tt>parallel</tt> will run as many tasks as the number of cores on the node, therefore maximizing resource usage. You can change this behaviour using the option <tt>--jobs</tt> followed by the number of simultaneous tasks that Gnu Parallel should run. When a task finishes, a new task will automatically be started by <tt>parallel</tt>. | ||
