Parallel SSH or PSSH, allows to execute commands on multiple linux hosts in parallel at the same time.

From the Linux HowTo guide:

OpenSSH is one of the most widely used and powerful tool available for Linux, that allows you to connect securely to remote Linux systems via a shell and allows you to transfer files securely to and from remote systems.

But the biggest disadvantages of OpenSSH is that, you cannot execute same command on multiple hosts at one go and OpenSSH is not developed to perform such tasks. This is where Parallel SSH or PSSH tool comes in handy, is a python based application, which allows you to execute commands on multiple hosts in parallel at the same time.
