As I recently posted, I've grown interested in enterprise networking gear (like #omnipath and #dpus like those from Nvidia, Marvell, etc.)

The #xeonphi has seemed like a somewhat exotic platform worth of exploration.

What I'm finding is a relatively sparse amount of video content about these subjects. ServeTheHome has a series on DPUs. There's a smattering of older marketing content on OmniPath when it was an Intel product. And likewise, there's a handful of videos showcasing the Phi.

The Intel #omnipath 100gb adapter wasn’t as simple as I’d hoped for. It simply doesn’t show up in lspci. It was $15, so not an issue.

The opa tools look interesting. I know I don’t know anything about these adapters. Maybe this one is a dud. Or more likely I don’t know how to use it. It’s not like I have a server-class system to install it in. I don’t expect much more than learning the basics of how it works. I was hoping I could wire two together and avoid the need for an expensive switch.

What If #OmniPath Morphs Into The Best #UltraEthernet?
Many #HPC centers in #US – importantly #Sandia and #LawrenceLivermore as well as the Texas Advanced Computing Center (#TACC) – wanted an alternative to #InfiniBand or proprietary interconnects like #HPE/#Cray’s Slingshot, and they have been funding the redevelopment of Omni-Path. And now, #CornelisNetworks is going to be intersecting its roadmap with Omni-Path switches and adapters with the #UEC roadmap.

Cornelis Unveils Ambitious Omni-Path Interconnect Roadmap - The Next Platform

As we are fond of pointing out, when it comes to high performance, low latency InfiniBand-style networks, Nvidia is not the only choice in town and has not been since the advent of InfiniBand interconnects back in the late 1990s. The folks at Cornelis Networks, which acquired the Omni-Path interconnect business from Intel three years
