Myrinet: High-Speed Network Technology for HPC

Myrinet is a high-speed, low-latency network technology designed for use in high-performance computing environments. It was developed in the 1990s by a group of researchers at the California Institute of Technology and the University of Tennessee.

Myrinet uses a switched fabric architecture to provide high-speed data transfer between nodes in a cluster. It supports both point-to-point and multicast communication, and can deliver sustained bandwidth of up to 2.4 gigabits per second per channel.

One of the key advantages of Myrinet is its low latency, which is achieved through the use of dedicated hardware for message routing and processing. This makes it well-suited for applications that require frequent communication between nodes, such as parallel computing and data-intensive scientific simulations.

Myrinet has been used in a variety of high-performance computing systems, including the IBM Blue Gene/L supercomputer and the SGI Altix 3700 Bx2. It has also been used in research projects in fields such as astrophysics, climate modeling, and molecular dynamics.
