HPC has been used for scientific and engineering computing since the inception of electronic computers. The perennial challenges that users have had to face include I/O bottlenecks, disparity between processing speed and memory access time, programmability due to the complexity of architectures and limitations in programming languages and compilers, and, in the last few decades, power consumption. Those challenges have been addressed and managed by the evolution of an HPC ecosystem that comprises architectures, mathematics, algorithms, programming languages and methodologies, system software and tools, libraries, community codes, and multidisciplinary teams and individuals.
