The user no longer needs to remember command names and key combinations. Geographical View of the System Hosts are grouped following a tree structure .
MANs can contain only LANs and LANs contain the hosts composing the metacomputer.
WAN and MANs are usually represented by geographical maps, in order to facilitate user exploration of the resources. Remote Compilation Compilation of modules on remote nodes is greatly simplified. The user selects a group of hosts to compile onto and a set of source files to be compiled. WAMM copies sources on remote nodes, compiles them in parallel and shows progress in separate windows, one for each host. The metacomputer configuration is specified through an external file, written in a simple declarative language.
