CSR-AES: Characterizing the Cooperative Parallel Behavior of GPUs and Multicore CPUs

通过提高时钟速度来改善微处理器的性能已不再现实。 作为回应，微处理器制造商选择通过使用多处理来提高性能。通过在单个芯片上安装多个复杂度较低的处理器，制造商正在创造每瓦和每平方毫米提供更高计算性能的CPU。 与此同时，GPU芯片使用相同的思想来极大地提高其总体性能，尽管它们解决不同形式的计算问题。本项目将这两种互补的资源作为一个单一的协同执行系统进行研究。 它的特点是如何最好地利用每一个，并确定？最佳位置？基于被计算的内容的性质和大小，将不同的计算功能分配给适当的处理单元。 它不仅会为一个特定的问题产生一个最佳点的解决方案，但会概括的整体问题方面：类型和大小的数据计算，CPU和GPU的速度，CPU和GPU处理器的数量，以及总线速度。迷你超级计算机用于解决计算密集型科学和渲染问题。 由于它的多核CPU/GPU混合，它将比任何桌面前辈拥有更多的综合计算能力，但它将把应用程序开发人员视为单一计算环境。 最重要的是，它不会比用户无论如何都会购买的图形桌面系统有更多的成本和占用空间。

Improving the performance of microprocessors by increasing the clock speed is no longer practical. In response, microprocessor manufacturers have chosen to increase performance through the use of multiprocessing. By populating a single die with multiple, less complicated processors, manufacturers are creating CPUs that provide higher computational performance per watt and per square millimeter. At the same time, GPU chips have used the same ideas to vastly improve their aggregate performance, although they address different forms of computational problems.This project is examining these two complementary resources as a single cooperative execution system. It is characterizing how to best take advantage of each, and ascertain the ?sweet spot? of assigning different computational functions to the appropriate processing units based on the nature and size of what is being computed. It will not just produce an optimal point solution for one particular problem, but will generalize the overall problem in terms of: the type and size of the data computation, the speed of the CPUs and GPUs, the number of CPU and GPU processors, and the bus speed.The result of this research will be to create a desktop ?mini-supercomputer? for solving compute-intensive scientific and rendering problems. Because of its multicore CPU/GPU mix, it will have more combined compute power than any of its desktop predecessors, but it will look to an application developer as a single compute environment. Best of all, it will have no more cost and footprint than the graphical desktop system that the user would have bought anyway.
