-While GNU parallel can be used across multiple nodes, it can have problems doing so, and it is not recommended, in particular in the context of a lot of short jobs. That is because it needs to start an SSH session on remote nodes, which is an operation which can hang, and which requires multiple seconds. If you choose to use it, make sure you add a delay between jobs of 30 seconds or more, using the option <tt>--sshdelay 30</tt>
