Executive Summary

The hardware trend toward multicore processors has so far been driven by technology limitations of wire delays, power efficiency, and limited capability to exploit instruction-level parallelism. Software evolution has lead to the rise of the cloud. This multicore + cloud evolution provides several challenges and has led to a call for parallelism. This paper examines the drivers behind these trends to address three fallacies: software is driven by hardware, multicores will be everywhere, and multicore hardware implies parallelism is exposed to all developers.
