Myrinet is a family of high-performance network interface cards (NICs) and network switches produced by Myricom, Inc. (Myrinet® and Myricom® are registered trademarks of Myricom, Inc.) Some salient features of Myrinet are that it utilizes wormhole switching and emphasizes fully programmable NICs and simple switches.



The Myrinet network [3] is a direct descendent of Caltech’s Mosaic C multicomputer [11] and USC/ISI’s ATOMIC local-area network (LAN) [6]. The Mosaic C was based on custom processors that integrated a network interface, router, and simple CPU onto a single die. Although the Mosaic C processor was intended to be used as the building block for a massively parallel processor, the ATOMIC project investigated using Mosaic C processors in a LAN setting as intelligent NICs – protocol processors – as a means for providing high-speed communication to nodes with more...
