This paper presents a retrospective view of the Charlotte distributed operating system, which is intended as a testbed for developing techniques and tools for exploiting large-grain parallelism to solve computation-intensive problems. Charlotte was constructed over the course of approximately 5 years, going through several distinct versions as the(More)
This paper presents a retrospective view of the Charlotte distributed operating system, a testbed for developing techniques and tools to solve computation-intensive problems with large-grain paral-lelism. The final version of Charlotte runs on the Crystal multicom-puter, a collection of VAX-111750 computers connected by a local-area network. The(More)
RP3, the Research Parallel Processing Prototype, was a research vehicle for exploring the hardware and software aspects of highly parallel computation. RP3 was a shared-memory machine that was designed to be scalable to 512 processors; a 64-processor machine was in operation from October 1988 through March 1991. A parallel-programming environment based on(More)
1. Introduction Charlotte is a distributed openting system currently in production use at the University of Wisconsin-Madison [1,2,5]. Charlotte is intended as a testbed for developing techniques and IOOls for exploiting large-grain paraIlelism to solve computation-intensive problems. It runs 011 the Crystal network (4), which contains 20 V AX-11nSO(More)
