In the June 2014 TOP500 list, the number of supercomputers using
interconnect was 1 (0.2%).
was promoted as having lower protocol overhead than standards such as Ethernet, and therefore better throughput, less interference, and lower latency while using the host CPU. Although it can be used as a traditional networking system,
is often used directly by programs that "know" about it, thereby bypassing a call into the operating system.
According to Myricom, 141 (28.2%) of the June 2005 TOP500 supercomputers used
technology. In the November 2005 TOP500, the number of supercomputers using
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%.
physically consists of two fibre optic cables, upstream and downstream, connected to the host computers with a single connector. Machines are connected via low-overhead routers and switches, as opposed to connecting one machine directly to another.
includes a number of fault-tolerance features, mostly backed by the switches. These include flow control, error control, and "heartbeat" monitoring on every link. The "fourth-generation"
, called Myri-10G, supported a 10 Gbit/s data rate and can use 10 Gigabit Ethernet on PHY, the physical layer (cables, connectors, distances, signaling). Myri-10G started shipping at the end of 2005.
When using source routing with
, the sender of the packet prepends the complete route, one byte for every crossbar, to each packet header.
The Portals 3 specification has been implemented several times, first on ASCI Red, then on CPlant over
, Linux and the Cray XT family.
is a lightweight protocol with little overhead that allows it to operate with throughput close to the basic signaling speed of the physical layer.For supercomputing, the low latency of
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.
Two kinds of pass-through module are available: copper pass-through and fibre pass-through. The copper pass-through can be used only with Ethernet, while the Fibre pass-through can be used for Ethernet, SAN or
, ANSI/VITA 26-1998, is a high-speed local area networking system designed by the company Myricom to be used as an interconnect between multiple machines to form computer clusters.
In November, 2013, the assets of Myricom (including the
technology) were acquired by CSP Inc. In 2016, it was reported that Google had also offered to buy the company.
All the nodes are interconnected with a low latency (2.6 – 3.2 μs) and high bandwidth network called
. This network is used only for MPI messages of users' tasks.
QsNet was a high speed interconnect designed by Quadrics used in high-performance computing computer clusters, particularly Linux Beowulf Clusters. Although it can be used with TCP/IP; like SCI,
and InfiniBand it is usually used with a communication API such as Message Passing Interface (MPI) or SHMEM called from a parallel program.
PVFS uses a networking layer named BMI which provides a non-blocking message interface designed specifically for file systems. BMI has multiple implementation modules for a number of different networks used in high performance computing including TCP/IP,
, Infiniband, and Portals.
MS MPI can use any physical network, including Gigabit ethernet, Infiniband and
, for which a Winsock Direct driver has been provided. The Winsock Direct provider bypasses the TCP/IP stack of the OS and directly provides access to the networking hardware, using transport protocols tailored for the network type. In absence of such drivers, the TCP/IP stack can also be used.
LAM (Local Area Multicomputer) is an MPI programming environment and development system for heterogeneous computers on a network. With LAM/MPI, a dedicated computer cluster or an existing network computing infrastructure can act as a single parallel computing resource. LAM/MPI is considered to be "cluster friendly", in that it offers daemon-based process startup/control as well as fast client-to-client message passing protocols. LAM/MPI can use TCP/IP, shared memory,
(GM), or Infiniband (mVAPI) for message passing.
Server farms are commonly used for cluster computing. Many modern supercomputers comprise giant server farms of high-speed processors connected by either Gigabit Ethernet or custom interconnects such as Infiniband or
. Web hosting is a common use of a server farm; such a system is sometimes collectively referred to as a "web farm". Other uses of server farms include scientific simulations (such as computational fluid dynamics) and the rendering of 3D computer generated imagery (also see render farm).
The BladeCenter can have a total of four switch modules, but two of the switch module bays can take only an Ethernet switche or Ethernet pass-though. To use the other switch module bays, a daughtercard needs to be installed on each blade that needs it, to provide the required SAN, Ethernet, InfiniBand or
function. Mixing of different type daughtercards in the same BladeCenter chassis is not allowed.
