-What this example does is that it finds a whole lot of scripts in a directory and gets gnu parallel to run them. The -j 6 options tells gnu parallel to run 6 jobs per node, while the -M option tells it to use ssh's ControlMaster (which is required when you're running more that 15 (ish) sub-jobs per node).+What this example does is that it finds a whole lot of scripts in a directory and gets gnu parallel to run them. The -j 6 options tells gnu parallel to run 6 jobs per node, while the -M and --sshdelay 0.2 options tells it to use ssh's ControlMaster and to have a delay between establishing links to the same node.
