Multiple round trips across the mem PCI bus for data from/to GPU/SSD/Network are killing us in ML. Time to change how Linux handles it say Mina Almasry et al in this @netdev01 0x17 talk. Exciting times in Linux and the networking world!!!😹 netdevconf.info/0x17/5 #netdevconf

This Thursday, at netdev 0x16, I talk about how RDMA concepts can be used with socket based networking to achieve most of the properties needed to scale up to high flow rates (netdevconf.info/0x16/session…).

I've been doing a lot of Go rtnetlink plumbing recently and I think it's time to add nexthops API support to github.com/jsimonetti/rtnetl…!
Thanks @dsahern for your work on this, and for the very informative presentation: linuxplumbersconf.org/event/… #golang #linux #networking

Listened to the latest Kernel of Truth podcast from @CumulusNetworks while working out. Good updates on FRR from @menotyousharp. Loved the progress on nexthop groups. Look forward to updates on the route install times.
