National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

ATOMIC: A High-Speed Local Communication Architecture.

ADA292493

Publication Date	1994
Personal Author	Felderman, R.; DeSchon, A.; Cohen, D.; Finn, G.
Page Count	25
Abstract	ATOMIC is an inexpensive high-speed LAN built by USC/ISI It is based upon Mosaic technology developed for fine-grain, message-passing, massively parallel computation. Each Mosaic processor is capable of routing variable length packets, while providing added value through simultaneous computing and buffering. ATOMIC adds a general routing capability to the native Mosaic wormhole routing through store-and-forward and path concatenation. ATOMIC aggregate bandwidth scales as the number of nodes increases, and it has a small interface cost. Each ATOMIC channel has a data carrying capacity of 500 Mb/s. A prototype ATOMIC LAN has been constructed along with host interfaces and software that provides full' TCP/IP compatibility. Using ATOMIC, 1,500 byte packets have been exchanged between hosts at an aggregate transfer rate of more than 1 Gb/s. Other tests have demonstrated throughput of 5.25 million packets per second over a single Mosaic channel. The architecture is flexible both in topology and functionality. This paper describes the architecture and performance of ATOMIC.
