摘要

Computational demands are growing in virtually every area of scientific research and advanced engineering, from space, climate, and genetics research, to automobile crash simulations and materials modeling. This is impacting not only high profile areas of business and educational research, where funding may be widely available, but many other disciplines where individuals or small teams are working under limited budgets, yet still need to solve complex problems that exceed the capacity of standard workstations or servers. High Performance Computing (HPC) clusters offer a solution that cuts across virtually the entire range of computational requirements. HPC clusters entered the arena about 15 years ago, and have come a long way in terms of cost, performance, and ease of use. They typically consist of networked computing platforms (nodes), with each node running its own image of the operating system. Complex workloads are then broken into chunks that can be processed simultaneously on multiple nodes, which communicate with each other using message-passing libraries to coordinate the computations.
