-In a distributed computing environments, network performance metrics help evaluate the system's ability to communicate between nodes effectively. These metrics are essential for distributed and tightly coupled workloads that span multiple nodes. Network bandwidth defines the maximum data transfer rate between nodes, whereas network latency measures the time required for messages to travel across the interconnect. Message rate, often evaluated with MPI micro-benchmarks, indicates how well the system handles frequent, small communications, which is particularly important for communication-intensive HPC applications.
