Net::OpenSSH::Parallel is an scheduler that can run commands in parallel in a set of hosts through SSH. It tries to find a compromise between being simple to use, efficient and covering a good part of the problem space of parallel process execution via SSH. Obviously, it is build on top of Net::OpenSSH! Common usage of the module is as follows: - Create a Net::OpenSSH::Parallel object. - Register the hosts where you want to run commands with the "add_host" method. - Queue the actions you want to run (commands, file copy operations, etc.) using the "push" method. - Call the "run" method and let the parallel scheduler take care of everything!
