GEXEC is a scalable cluster remote execution system which provides fast, RSA-authenticated remote execution of parallel and distributed jobs. It provides transparent forwarding of stdin, stdout, stderr, and signals to and from remote processes, provides local environment propagation, and is designed to be robust and to scale to systems of over 1000 nodes.
