Subject: [PATCH rdma-next 00/11] Elastic RDMA Adapter (ERDMA) driver
Date: Tue, 21 Dec 2021 10:48:47 +0800 [thread overview]
Message-ID: <20211221024858.25938-1-chengyou@linux.alibaba.com> (raw)
Hello all,
This patch set introduces the Elastic RDMA Adapter (ERDMA) driver, which
released in Apsara Conference 2021 by Alibaba.
ERDMA enables large-scale RDMA acceleration capability in Alibaba ECS
environment, initially offered in g7re instance. It can improve the
efficiency of large-scale distributed computing and communication
significantly and expand dynamically with the cluster scale of Alibaba
Cloud.
ERDMA is a RDMA networking adapter based on the Alibaba MOC hardware. It
works in the VPC network environment (overlay network), and uses iWarp
tranport protocol. ERDMA supports reliable connection (RC). ERDMA also
supports both kernel space and user space verbs. Now we have already
supported HPC/AI applications with libfabric, NoF and some other internal
verbs libraries, such as xrdma, epsl, etc,.
For the ECS instance with RDMA enabled, there are two kinds of devices
allocated, one for ERDMA, and one for the original netdev (virtio-net).
They are different PCI deivces. ERDMA driver can get the information about
which netdev attached to in its PCIe barspace (by MAC address matching).
Thanks,
Cheng Xu
