SUNMOS is an acronym for Sandia/UNM Operating System. It was originally developed for the nCUBE-2 MIMD supercomputer between January and December of 1991. Between April and August of 1993, SUNMOS was ported to the Intel Paragon. This document provides a quick overview of how to compile and run jobs using the SUNMOS environment on the Paragon. The primary goal of SUNMOS is to provide high performance message passing and process support an example of its capabilities, SUNMOS Release 1.4 occupies approximately 240K of memory on a Paragon node, and is able to send messages at bandwidths of 165 megabytes per second with latencies as low as 42 microseconds using Intel NX calls. By contrast, Release 1.2 of OSF/1 for the Paragon occupies approximately 7 megabytes of memory on a node, has a peak bandwidth of 65 megabytes per second, and latencies as low as 42 microseconds (the communication numbers are reported elsewhere in these proceedings).
