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.
Big memory is a term used to describe server workloads which need to run on machines with a large amount of RAM (random-access memory) memory. Some example workloads are databases, in-memory caches, and graph analytics. Or, more generally, data science and big data.Some database systems are designed to run mostly in memory, rarely if ever retrieving data from disk or flash memory.
