MYRINET MX DRIVER

If you are looking for general-purpose Open-MX citations, please use this one. 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. For instance, if you replace the 2. Open-MX is a high-performance implementation of the Myrinet Express message-passing stack over generic Ethernet networks. 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. This paper describes the initial design and performance of Open-MX stack.

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.

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.

In the November TOP, the number of supercomputers using Myrinet was down to computers, or Please help improve this article by adding citations to reliable sources. This 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.

The Open-MX latency depends on the processor frequency. Unsourced material may be challenged and removed.

Myrinet Express over Generic Ethernet Hardware

From Wikipedia, the free encyclopedia. MyriG started shipping at the end of 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. 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 is a lightweight protocol with little overhead that allows it to operate with myriner close to the basic signaling speed of the physical layer.
