 To run certain Batch jobs, you can take advantage of Azure VM sizes designed for large-scale computation. For example:
 
-* To run multi-instance [MPI workloads](batch-mpi.md), choose H-series or other sizes that have a network interface for Remote Direct Memory Access (RDMA). These sizes connect to an InfiniBand network for inter-node communication, which can accelerate MPI applications.

 * For CUDA applications, choose N-series sizes that include NVIDIA Tesla graphics processing unit (GPU) cards.
