Scalable UNIX Tools for Clusters

SUT is a collection of standard UNIX utilities like ls, rm, cp, etc. that are targeted at cluster use. These tools are based on a paper by William Gropp and Ewing Lusk entitled Unix Tools on Massively Parallel Processors. As it stands now, the tools in the SUT package do not conform to the syntax or semantics of those described in the paper for various reasons but in many cases, the current SUT package offers enhancements on the ideas presented in the paper.
