This report focuses on benchmarking and performance testing of the first Cray 1 supercomputer, specifically using the Lawrence Livermore Laboratory program kernels, known as Livermore Loops. The author provides results from their own conversion of the code to C, as well as results from similar vintage benchmarks like Linpack and Whetstone. The report highlights the significant difference in cost, weight, and power consumption between the Cray 1 and modern devices like the Raspberry Pi. Various benchmarking results for different platforms, including Raspberry Pi, Android, and Windows/Linux PCs, are presented to show performance variations over the years. The author also discusses their background activities, involvement in evaluating and acceptance testing supercomputers, and interactions with industry figures like Seymour Cray.
