00:32:29 Kate Hendle: Welcome to Day 1 of the Networking Tech Talk! Please put any questions you have for the speakers here in the chat. This is being recorded and will be available on our website on demand. 00:39:57 Kate Hendle: https://www.opencompute.org/events/past-events 00:58:08 Archna Haylock: Project Page: https://www.opencompute.org/projects/open-network-linux-onl 01:01:24 Archna Haylock: you can access to ONL mailing list and steve through the page 01:02:11 Archna Haylock: Enterprise Connectivity Solutions: https://www.opencompute.org/projects/enterprise-connectivity-solutions-ecs-incubation 01:30:00 Archna Haylock: The Networking SW workstream is being covered under the main Networking Project Calls. The next call is on June 13th at 10am PT. 01:30:50 Archna Haylock: OCP 2022 Global Summit Call for Papers has been launched. More info here; https://www.opencompute.org/summit/global-summit/call-for-papers 02:11:20 paul congdon: what standards body? 02:13:26 Yury Shefer: very cool - would be interesting to compare Adaptive Routing to AWS’ Scalable Reliable Datagram (SRD) transport performance (NCCL over EFA) 02:15:00 Alex Bortok: You mentioned some GPUs can sustain 200Gbps rates. When adaptive routing starts failing in terms of elephant flow bandwidth vs uplink speed 02:16:13 Madhu Paluru: More insights on how adaptive routing is mutli-vendor friendly? 02:18:02 Madhu Paluru: second question - does AR need an SDN controller to program it down or Switches itself instrument probes to determine how to do adaptive routing? 02:18:05 Moshe Voloshin: Some adapters react to congestion on a per destination basis. So if there is congestion on a flow going to dest 1 then all flow from the nic going to dest1 cut their rate. This could lead to underutilization of uncongested paths. Is this also taken care by adaptive routing? 02:22:06 Razvan Stan (Keysight): Does adaptive routing look at PFC or CNP packets comming back to help decide pick different links? 02:33:00 Steve Noble: TPM, Trusted Boot, Secure Boot, Verified Boot, a lot of work is being done in this area for switches. 02:41:30 Winston Liu: for the earlier adaptive routing talk, was the comparison between ecmp and adaptive routing done on 2 tier topology with every switch being either ecmp or adaptive throughout all switches? 02:46:55 Alex Bortok: how to deal with increased blast radius for EoR case? 02:47:00 Bruck Girmay: Great presentation Dave! 02:49:20 Alex Bortok: agree, smart cables might be a good fit here 03:18:46 Simon: Thanks all, nice presentation
