What is High Performance Computing

Serial computing

  • Computational tasks are processed in sequential order on one CPU.
  • Most of the generic software was developed for serial computing.
  • Doesn't take advantage of the modern multi-core architectures.

  • Parallel (High Performance) Computing

  • Computational tasks are processed concurrently on the different CPUs or cores.
  • The platform can be a single multi-core host or a computational cluster of network interconnected hosts or combination of both.
  • Special programming methods and software are required, for example, OpenMP or MPI.
