“High-performance computing” redirects here. For narrower definitions of HPC, see High-throughput computing and Many-task computing. For other uses, see Supercomputer (disambiguation).
A supercomputer is a computer with a high level of performance compared to a general-purpose computer.
Performance of a supercomputer is measured in floating-point operations per
second (FLOPS) instead of million instructions per second (MIPS). As of 2017,
there are supercomputers which can perform up to nearly a hundred quadrillion FLOPS.
As of November 2017, all of the world’s fastest 500 supercomputers run Linux-based operating systems. Additional research is being conducted in China, the United States, the European Union, Taiwan and Japan to build even
faster, more powerful and more technologically superior exascale supercomputers.
