Myrinet is a new type of local-area network (LAN) based on the technology used for packet communication and switching within "massivelyparallel processors" (MPPs). Think of Myrinet as an MPP message-passing network that can span campus dimensions, rather than as a wide-area telecommunications network that is operating in close quarters. The technical steps(More)
The torus routing chip (TRC) is a selftimed chip that performs deadlock-freecut-through routing ink-aryn-cube multiprocessor interconnection networks using a new method of deadlock avoidance calledvirtual channels. A prototype TRC with byte wide self-timed communication channels achieved on first silicon a throughput of 64 Mbits/s in each dimension, about(More)
Current ber optic networks e ectively provide local connectivity among end user computing devices, and can serve as backbone fabric between LAN subnets across campus and metropolitan areas. However, combining both stream service (in which ATM excels) and low latency datagram service (in which cluster networks like Myrinet and POLO excel) has been di cult to(More)
Sixty-four small computers are connected by a network of point-to-point communication channels in the plan of a binary 6-cube. This “Cosmic Cube” computer is a hardware simulation of a future VLSI implementation that will consist of single-chip nodes. The machine offers high degrees of concurrency in applications and suggests that future(More)
yrinet is a new type of local area network based on the technology used for packet communication and switching within massively parallel processors. Think of it as an MPP network spanning campus-wide dimensions, rather than as a wide-area telecommunications network operating in close quarters. In creating Myrinet, we devised robust, 25-meter communication(More)
Inf, r o d u c t i o n Message-passing concurrent computers, also known as multicomputers, such as the Calteeh Cosmic Cube [I] and its commercial descendents, consist of many computing nodes that interact with each other by sending and receiving messages over communication channels between the nodes [2 i. The communication networks of the second-generation(More)
During the period following the completion of the Cosmic Cube experiment [1], and while commercial descendants of this first-generation multicomputer (message-passing concurrent computer) were spreading through a community that includes many of the attendees of this conference, members of our research group were developing a set of ideas about the physical(More)
1. Overview and Summary 1.1 Scope of this Report This document is a summary of the research activities and results for the seven-month period, 1 April 1987 to 31 October 1987, under the Defense Advanced Research Project Agency (DARPA) Submicron Systems Architecture Project. Technical reports covering parts of the project in detail are listed following these(More)
