The BESM-6 Computer and Its Performance Evaluation in an Emulator

This article explores the legendary Soviet BESM-6 computer, often called a "millionaire" for its ability to perform one million operations per second. The author examines the machine's architecture and instruction set, offering readers a deep dive into computing history. The piece details running programs on the Besm6.Net emulator and conducts performance testing using classic benchmarks like Dhrystone, Whetstone, Memspeed, and MP-MFLOPS. Special attention is given to comparing emulator speeds on modern hardware with estimated execution times on the original BESM-6 hardware. This technical review provides insight into the real capabilities of 1960s architecture and clarifies what the marketing term "one million operations per second" actually meant in the context of various computational tasks.
