We now support Linux remote direct memory access (RDMA) technology, enabling scientists and engineers to solve complex problems by using simulations running on Azure. RDMA technology allows A8 and A9 Linux virtual machines in Azure to directly communicate through the Infiniband network.
This helps enable faster communication between virtual machines at low latency for parallel workloads and applications that take advantage of the Message Passing Interface (MPI) stack. With this release, Intel MPI is supported.
