ARCHIVED: In high-performance computing, what are Rmax and Rpeak?

In high-performance computing, Rmax and Rpeak are scores used to rank supercomputers based on their performance using the LINPACK Benchmark. A system's Rmax score describes its maximal achieved performance; the Rpeak score describes its theoretical peak performance. Values for both scores are usually represented in teraFLOPS or petaFLOPS.

The website publishes biannual lists of the 500 most powerful supercomputers in the world based on their Rmax and Rpeak scores.
