MPP UNIX enhancements for OLTP applications

This paper describes an MPP UNIX in terms of goals, implementation and initial experience in using it lo port OLTP applications. Most MPP Unix systems strive towards the goal of a conventional but massively scaled up shared memory multiprocessor. In reality this goal has never been achieved without compromising scalability or fault-tolerance. The Infinity architeclure achieves scalability with no single point of failure by running a separate copy of UNIX on each node. UNIX extensions make it appear as a single machine 20 applications. Results indicate that complex OLTP applications can be ported with ease; other applications may need to be rewritten to take advantage of the MPP
