That is a very strange statement to make on a Perl beginners list, not least because it's complete bosh. What better language to simple network control structures? This is exactly the sort of task that Perl accomplishes better and more easily than any other language out there, and why it's "the glue of the internet." In particular, this sounds like a job for RPC::Lite. The issue, though, isn't just how processes communicate with each other--any RPC/IPC implementation can handle that for you transparently; I suggested RPC::Lite but Moose::Async or something similar is fine, too, although probably overkill--it's also how to launch the program on the remote machine. Here you really have two options: you can set up listener daemons on the worker machines that wait fro input from the console and launch workers, or you can use something like Net::SSH2 to login to the worker machine and launch a new process each time. Also, be careful with your terminology. You'll get better help, here, if you ask the right questions. Network/socket communication and IPC are two very different things. Most operating systems (in fact all but one that I'm aware of; the possible exception being Plan9) localize processes to the running kernel. Processes (whether perl programs or otherwise) can't fork children on other machines or deliver SIGTERM across the network, and asking about threads and remote machines in the same breath is likely to yield strange responses and/or confused silence.
