Understanding the Design Trade-Offs Among Current Multicore Systems for Numerical Computations

Free registration required

Executive Summary

In this paper, the authors empirically evaluate fundamental design trade-offs among the most recent multi-core processors and accelerator technologies. Their primary aim is to aid application designers in better mapping their software to the most suitable architecture, with an additional goal of influencing future computing system design. They specifically examine five architectures, based on: the Intel quad-core Harpertown processor, the AMD quad-core Barcelona processor, the Sony-Toshiba-IBM Cell Broadband Engine processors (both the first-generation chip and the second-generation PowerXCell 8i), and the NVIDIA Tesla C1060 GPU.
