In the November 2005 TOP500, the number of supercomputers using Myrinet was down to 101 computers, or 20. 2 %, in November 2006, 79 ( 15. 8 %), and by November 2007, 18 ( 3. 6 %), a long way behind Gigabit Ethernet at 54 % and Infiniband at 24. 2 %.

In the latest TOP500 list ( June 2011 ), the number of supercomputers using Myrinet interconnect is 4 ( 0. 8 %).

The messages can be sent by a number of communication mechanisms, such as TCP / IP over Ethernet, or specialized high-speed interconnects such as Myrinet and Supercomputer Interconnect.

Myrinet, ANSI / VITA 26-1998, is a high-speed local area networking system designed by Myricom to be used as an interconnect between multiple machines to form computer clusters.

Although it can be used as a traditional networking system, Myrinet is often used directly by programs that " know " about it, thereby bypassing a call into the operating system.

However, for supercomputing, the low latency of Myrinet is even more important than its throughput performance, since, according to Amdahl's law, a high-performance parallel system tends to be bottlenecked by its slowest sequential process, which in all but the most embarrassingly parallel supercomputer workloads is often the latency of message transmission across the network.

This model has further been fueled by the availability of high performance interconnects such as Myrinet and InfiniBand technologies.

Many modern supercomputers comprise giant server farms of high-speed processors connected by either Gigabit Ethernet or custom interconnects such as Infiniband or Myrinet.

Like other interconnects such as Myrinet very large systems can be built by using multiple switch chassis arranged as spine ( top-level ) and leaf ( node-level ) switches.

In contrast, the Send / Recv model used by other zero-copy HPC interconnects, such as Myrinet or Quadrics, does not have the 1-sided communication problem or the memory paging problem described above, yet provides comparable reductions in latency when used in conjunction with HPC communication frameworks that expose the Send / Recv model to the programmer ( such as MPI ).

Remote Direct Memory Access ( RDMA ) is permitted when supported by underlying networks such as Quadrics Elan, Myrinet, and InfiniBand.

The computing nodes of MareNostrum communicate primarily through a high bandwidth, low latency Myrinet network consisting of integrated Myrinet adapters on each server blade and switched fabric of 12 Myrinet switches.

Myrinet has much lower protocol overhead than standards such as Ethernet, and therefore provides better throughput, less interference, and lower latency while using the host CPU.

Myrinet physically consists of two fibre optic cables, upstream and downstream, connected to the host computers with a single connector.

Myrinet is a lightweight protocol with little overhead that allows it to operate with throughput close to the basic signaling speed of the physical layer.

On the latest 2. 0 Gbit / s links, Myrinet often runs at 1. 98 Gbit / s of sustained throughput, considerably better than what Ethernet offers, which varies from 0. 6 to 1. 9 Gbit / s, depending on load.

According to Myricom, 141 ( 28. 2 %) of the June 2005 TOP500 supercomputers used Myrinet technology.

Although it can be used with TCP / IP ; like SCI, Myrinet and Infiniband it is usually used with a communication API such as MPI or SHMEM called from a parallel program.
