 [Azure Accelerated Networking](https://azure.microsoft.com/blog/maximize-your-vm-s-performance-with-accelerated-networking-now-generally-available-for-both-windows-and-linux/) is now available on the RDMA and InfiniBand capable and SR-IOV enabled VM sizes [HB](../../hb-series.md), [HC](../../hc-series.md), [HBv2](../../hbv2-series.md), [HBv3](../../hbv3-series.md), [NDv2](../../ndv2-series.md) and [NDv4](../../nda100-v4-series.md). This capability now allows enhanced throughout (up to 30 Gbps) and latencies over the Azure Ethernet network. Though this is separate from the RDMA capabilities over the InfiniBand network, some platform changes for this capability may impact behavior of certain MPI implementations when running jobs over InfiniBand. Specifically the InfiniBand interface on some VMs may have a slightly different name (mlx5_1 as opposed to earlier mlx5_0). This may require tweaking of the MPI command lines especially when using the UCX interface (commonly with OpenMPI and HPC-X). 
 
-The simplest solution currently is to use the latest HPC-X on the CentOS-HPC VM images where we rename the IB/AN interfaces accordingly or to run the [script](https://github.com/Azure/azhpc-images/blob/master/common/install_azure_persistent_rdma_naming.sh) to rename the InfiniBand interface.
