A remote direct memory access (RDMA) network group.

A cluster network on a compute cluster is a group of high performance computing (HPC), GPU, or optimized instances that are connected with an ultra low-latency network.

Use compute clusters when you want to manage instances in the cluster individually, or when you want to use different types of instances in the RDMA network group.

For details about cluster networks that use instance pools to manage groups of identical instances, see ClusterNetwork.
