  • Efficiency, Energy Efficiency and Programming of Accelerated HPC Servers: Highlights of PRACE Studies
    Efficiency, energy efficiency and programming of accelerated HPC servers: Highlights of PRACE studies Lennart Johnsson Department of Computer Science University of Houston and School of Computer Science and Communications KTH To appear in Springer Verlag “GPU Solutions to Multi-scale Problems in Science and Engineering”, 2011 2 Lennart Johnsson Abstract During the last few years the convergence in architecture for High-Performance Computing systems that took place for over a decade has been replaced by a di- vergence. The divergence is driven by the quest for performance, cost- performance and in the last few years also energy consumption that during the life-time of a system have come to exceed the HPC system cost in many cases. Mass market, specialized processors, such as the Cell Broadband Engine (CBE) and Graphics Processors, have received particular attention, the latter especially after hardware support for double-precision floating-point arithmetic was intro- duced about three years ago. The recent support of Error Correcting Code (ECC) for memory and significantly enhanced performance for double-precision arithme- tic in the current generation of Graphic Processing Units (GPUs) have further so- lidified the interest in GPUs for HPC. In order to assess the issues involved in potentially deploying clusters with nodes consisting of commodity microprocessors with some type of specialized processor for enhanced performance or enhanced energy efficiency or both for science and engineering workloads, PRACE, the Partnership for Advanced Com- puting in Europe, undertook a study that included three types of accelerators, the CBE, GPUs and ClearSpeed, and tools for their programming. The study focused on assessing performance, efficiency, power efficiency for double-precision arithmetic and programmer productivity.

Terrell, Dean of the Robert B. Toulouse School of Graduate Studies Fleming, Robert. General Purpose Programming on Modern Graphics Hardware. Master of Science (Computer Science), May 2008, 90 pp., 1 table, 3 figures, references, 124 titles. I start with a brief introduction to the graphics processing unit (GPU) as well as general-purpose computation on modern graphics hardware (GPGPU). Next, I explore the motivations for GPGPU programming, and the capabilities of modern GPUs (including advantages and disadvantages). Also, I give the background required for further exploring GPU programming, including the terminology used and the resources available. Finally, I include a comprehensive survey of previous and current GPGPU work, and end with a look at the future of GPU programming.

INTRODUCTION Heterogeneous multiprocessors are increasingly important in the Multiprocessors have emerged as mainstream computing plat- multi-core era due to their potential for high performance and en- forms nowadays. Among them, an increasingly popular class are ergy efficiency. In order for software to fully realize this potential, those with heterogeneous architectures. By providing processing the step that maps computations to processing elements must be as elements (PEs)1 of different performance/energy characteristics on automated as possible. However, the state-of-the-art approach is the same machine, these architectures could deliver high perfor- to rely on the programmer to specify this mapping manually and mance and energy efficiency [14]. The most well-known hetero- statically. This approach is not only labor intensive but also not geneous architecture today is probably the IBM/Sony Cell archi- adaptable to changes in runtime environments like problem sizes tecture, which consists of a Power processor and eight synergistic and hardware/software configurations. In this study, we propose processors [26]. In the personal computer (PC) world, a desktop adaptive mapping, a fully automatic technique to map computa- now has a multicore CPU and a GPU, exposing multiple levels of tions to processing elements on a CPU+GPU machine.
