# Top 500 Supercomputer Total Performance

### Question

In the seven decades since the invention of the point-contact transistor at Bell Labs, relentless progress in the development of semiconductor devices — Moore’s law — has been achieved despite regular warnings from industry observers about impending limits.

The TOP500 project collects and ranks system performance metrics of the most powerful non-distributed computer systems in the world. The project was started in 1993 and publishes an updated list of the supercomputers twice a year. The first of these updates always coincides with the International Supercomputing Conference in June, and the second is presented at the ACM/IEEE Supercomputing Conference in November.

The TOP500 ranks high-performance computing (HPC) by recording how fast a computer system solves a dense n by n system of linear equations in double precision (64 bits) arithmetic on distributed-memory computers (TOP500, 2019). This is an implementation of the High Performance Computing Linpack Benchmark.

What will be the sum of the performance (in exaFLOPS) of the top 500 supercomputers in the following dates?

The following sub-questions will resolve as the sum of performance (at Rmax) in exaFLOPS (1 exaFLOP = $10^{18}$ FLOPS) of all supercomputers listed by TOP500 for the respective date.

This question will resolve as Ambiguous if TOP500 stops reporting performance in terms of Rmax measured in TFlop/s on the Linpack benchmark.
