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.

Extended revision of the Euro-Par paper, discussing cache-affinity-related problems in the Open-MX receive stack and improving performance by enhancing the cache-efficiency from the NIC up to the application. 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.

Myrinet includes a number of fault-tolerance features, mostly backed by the switches. MyriG started shipping at the end of These include flow control, error control, and “heartbeat” monitoring on every link.

This paper discuss how to add basic support for Open-MX-aware coalescing in interconnecf NIC so as to achieve optimal latency without disturbing message rate or increasing the host load.

From Wikipedia, the free encyclopedia. Retrieved September 1, For configuration details, see the headers of the corresponding output file. Unsourced material may be challenged and removed. In inteerconnect November Interconnecf, the number of supercomputers using Myrinet was down to computers, or Support for Linux kernel starting with 2.

Myrinet physically consists of two fibre optic cables, upstream and downstream, connected to the host computers with a single connector. For additional discussions regarding the Open-MX development, see also the open-mx-devel mailing list but be aware that open-mx-announce is the only way to be informed about important news and releases.

This paper describes the initial design and performance of Open-MX stack.

See also the news archive. Open-MX development resources are maintained on the Inria Gforge server. This paper describes an innovative memory pinning optimization in Open-MX based on pinning pages on-demand, overlapping this process with the communication, and decoupling it from user-space so as to implement a safe pinning cache using the kernel MMU-Notifier framework.

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

Myrinet – Wikipedia

According to Myricom, Myrinet was promoted as having lower protocol overhead than standards such as Ethernetand therefore better throughputless interference, and lower interconneect while using the host CPU.

For instance, if you replace the 2. The design of Open-MX is described in several papers. If you are looking for general-purpose Open-MX citations, please use this one.
