-The [Message Passing Interface (MPI)](https://en.wikipedia.org/wiki/Message_Passing_Interface) is an open library and de-facto standard for distributed memory parallelization. It is commonly used across many HPC workloads. HPC workloads on the [RDMA capable](../../sizes-hpc.md#rdma-capable-instances) [HB-series](sizes-hpc.md) and [N-series](sizes-gpu.md) VMs can use MPI to communicate over the low latency and high bandwidth InfiniBand network.

 - The SR-IOV enabled VM sizes on Azure allow almost any flavor of MPI to be used with Mellanox OFED.
 - On non-SR-IOV enabled VMs, supported MPI implementations use the Microsoft Network Direct (ND) interface to communicate between VMs. Hence, only Microsoft MPI (MS-MPI) 2012 R2 or later and Intel MPI 5.x versions are supported. Later versions (2017, 2018) of the Intel MPI runtime library may or may not be compatible with the Azure RDMA drivers.
 
-For SR-IOV enabled [RDMA capable VMs](../../sizes-hpc.md#rdma-capable-instances), [CentOS-HPC VM images](configure.md#centos-hpc-vm-images) version 7.6 and later are suitable. These VM images come optimized and pre-loaded with the OFED drivers for RDMA and various commonly used MPI libraries and scientific computing packages and are the easiest way to get started.

 Though the examples here are for RHEL/CentOS, but the steps are general and can be used for any compatible Linux operating system such as Ubuntu (16.04, 18.04 19.04, 20.04) and SLES (12 SP4 and 15). More examples for setting up other MPI implementations on others distros is on the [azhpc-images repo](https://github.com/Azure/azhpc-images/blob/master/ubuntu/ubuntu-18.x/ubuntu-18.04-hpc/install_mpis.sh).
