Аннотация:The paper discusses the stages of evolution of the Algo500 scalable digital platform in general and its components AlgoWiki, CompZoo and PerfData in particular. The main attention is paid to the system analysis of the subject areas of the AlgoWiki, CompZoo and PerfData components. The concept of “supercomputer experiment” is introduced to systematize entering information about program runs into the PerfData component and to build various ratings based on the results of runs. The block diagram of the AlgoWiki, CompZoo and PerfData components integration into the Algo500 platform is described.
