not really. they conflate infiniband with RoCE which given they have different semantics on congestion control, I'd say is a bit of a whoopsey.
if they are using RoCE, are they using DCB to avoid loss(well make it "lossless")? the paper implies otherwise.
- birdyrooster 4y agoFor those who don’t know, RoCE is somewhat of a failure in the marketplace right now.
- throw0101a 4y agoFor those who don't know, RoCE = RDMA over Converged Ethernet. * https://en.wikipedia.org/wiki/RDMA_over_Converged_Ethernet https://en.wikipedia.org/wiki/RDMA_over_Converged_Ethernet > RDMA over Converged Ethernet (RoCE) is a network protocol that leverages Remote Direct Memory Access (RDMA) capabilities to accelerate communications between applications hosted on clusters of servers and storage arrays. RoCE incorporates the IBTA RDMA semantics to allow devices to perform direct memory-to-memory transfers at the application level without involving the host CPU. Both the transport processing and the memory translation and placement are performed by the hardware which enables lower latency, higher throughput, and better performance compared to software-based protocols. * https://docs.nvidia.com/networking/pages/viewpage.action?pageId=19807245 https://docs.nvidia.com/networking/pages/viewpage.action?pag...
