Looking back on the language and hardware revolutions

Abstract

This paper reports and analyzes measured chip power and performance on five process technology generations executing 61 diverse benchmarks with a rigorous methodology. We measure representative Intel IA32 processors with technologies ranging from 130nm to 32nm while they execute sequential and parallel benchmarks written in native and managed languages. During this period, hardware and software changed substantially: (1) hardware vendors delivered chip multiprocessors instead of uniprocessors, and independently (2) software developers increasingly chose managed languages instead of native languages. This quantitative data reveals the extent of some known and previously unobserved hardware and software trends. Two themes emerge.
