Now that all the hosts have been entered, the user can proceed to enter the host commands. The commands to be entered for a particular host will be those necessary to compile the manager.c and worker.c programs. In this example, the general procedure for compiling these programs will be to change to the remote-host directory in which the source files are located and to issue the ``make'' command. The makefile appropriate to the particular host will have already been sent as part of the file-transfer phase of the process of building the parallel application.
