gRPC+MPI 是否需要 RDMA？
Does gRPC+MPI require RDMA?
Tensorflow 在指定通信协议时允许选项 "gRPC"、"gRPC+verbs" 和 "gRPC+mpi"。在 gRPC+verbs documentation, it clearly states that this protocol is based on RDMA. Meanwhile, in the gRPC+MPI documentation, it doesn't imply this at all, and initially I assumed that gRPC+mpi can run on any underlying network. However, this 研究论文中暗示 gRPC+mpi 需要 运行 over RDMA（见第 3 页末尾）。我误解了研究论文吗？ gRPC+MPI 实际上可以 运行 通过任何网络吗？
我找到了答案，同一篇研究论文的第 4 页表明 MPI 通道能够支持 RDMA。
