Abstract
The HetNOS network operating system is a set of software layers laid over "native" operating systems to provide a distributed programming platform. The environment is composed of the HetNOS shell command language and the system calls interface (accessed through a procedure library). In both levels of interaction with users, the set of machines integrated by HetNOS are seen as a distributed virtual machine. The HetNOS command interpreter, namely hsh, implements most functions present in more traditional command interpreters. It is possible to spawn, monitor, and terminate processes in any host in the network like in the local case. The HetNOS distributed kernel uses a symbolic, global, location independent, process identification scheme. Distributed applications are split into sequential processes, which interact with each other by message exchange. There are neither connections nor ports, being the communication mechanism strongly influenced by the process identification scheme. This ...
