This article needs additional citations for verification. 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.

It provides application-level with wire-protocol compatibility with the native MXoE Myrinet Express over Ethernet stack. Myrinet includes a number of fault-tolerance features, mostly backed by the switches. For instance, if you replace the 2. For configuration details, see the headers of the corresponding output file. This paper discussed cache-affinity-related problems in the Open-MX receive stack.

The Open-MX latency depends on the processor frequency.

Please help improve this article by adding citations to reliable sources. 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.

This page was last edited on 13 Decemberat Summary Open-MX is a high-performance implementation of the Myrient Express message-passing stack over generic Ethernet networks. Myrinet physically consists of two fibre optic cables, upstream and downstream, connected to the host computers with a single connector. Direct access to all raw performance numbers is available here. Articles needing additional references from September All articles needing additional references Webarchive template wayback links.

Unsourced material may be challenged and removed. The design of Open-MX is described in several papers.

According to Myricom, Machines are connected via low-overhead routers and switchesas opposed to connecting one machine directly to another.

It shows that adding Open-MX protocol knowledge in the NIC firmware and combining it myrint multiqueue capabilities improves performance by enhancing the cache-efficiency from the NIC up to the application.

For supercomputing, the low latency of Myrinet is even more important than its throughput performance, since, according to Amdahl’s lawa 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.

Retrieved September 1, Myrijet paper describes the design of the Open-MX stack and of its copy offload mechanism, and how the MX wire protocol and host configuration may be tuned for better performance. To get the latest Open-MX news, you should subscribe to the open-mx-announce mailing list. Myrinet was promoted as having lower protocol overhead than standards such as Ethernetand therefore better throughputless interference, and myrient latency while using the host CPU.

Bug reports and questions should be sent on the project tracker or on the open-mx-devel mailing list.
