Myrinet physically consists of two fibre optic cables, upstream and downstream, connected to the host computers with a single connector. This article needs additional citations for verification. It provides application-level with wire-protocol compatibility with the native MXoE Myrinet Express over Ethernet stack.
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.
[Rocks-Discuss] Processor limits for MX (Myrinet)
September Learn how and when to remove this template message. It shows that adding Open-MX protocol knowledge in the NIC firmware and combining it with multiqueue capabilities improves myrrinet by enhancing the cache-efficiency from the NIC up to the application.
Unsourced material may be challenged and removed. This paper discuss how to add basic support for Open-MX-aware coalescing in regular NIC so as to achieve optimal latency without disturbing message rate or increasing the host load.
Myrinet – Wikipedia
This page was last edited on 13 Decemberat Open-MX development resources are maintained on the Inria Gforge server. Summary Myrineh is a high-performance implementation of the Myrinet Express message-passing stack over generic Ethernet networks.
Myrinet was promoted as having lower protocol overhead than standards such as Ethernetand therefore better throughput myrindt, less interference, and lower latency while using the host CPU. 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.
