Starting an HPJ program

A Node instance can be started on any host running a suitable daemon. A master server process records the pool of slave daemons currently running. When a new daemon is started, it registers with this central server. Clients may request a list of hosts running daemons from the main server, then ask for a particular Java object file to be run on any subset of those hosts. Typically the client is an applet running in a browser, and the main HPJ server runs on the same host as an HTTP server from which the applet was downloaded.
