HPC systems overview
HPC systems are engineered with three main components: compute, storage, and networking, including compute network storage. Compute servers, or nodes, form the heart of an HPC cluster, collaborating to execute tasks in parallel. These nodes can number in the hundreds or thousands, each performing specific tasks to optimize performance. Tightly coupled workloads are processed by different nodes in a cluster, where each node handles interdependent tasks that rely on low-latency communication and share resources to achieve a common goal. Each node in an HPC cluster typically uses high-performance multi-core CPUs or GPUs. The sheer number of nodes and their synchronized operations allow HPC systems to perform calculations at lightning speeds.
