  • Introduction to High Performance Computing
    Introduction to High Performance Computing Shaohao Chen Research Computing Services (RCS) Boston University Outline • What is HPC? Why computer cluster? • Basic structure of a computer cluster • Computer performance and the top 500 list • HPC for scientific research and parallel computing • National-wide HPC resources: XSEDE • BU SCC and RCS tutorials What is HPC? • High Performance Computing (HPC) refers to the practice of aggregating computing power in order to solve large problems in science, engineering, or business. • Purpose of HPC: accelerates computer programs, and thus accelerates work process. • Computer cluster: A set of connected computers that work together. They can be viewed as a single system. • Similar terminologies: supercomputing, parallel computing. • Parallel computing: many computations are carried out simultaneously, typically computed on a computer cluster. • Related terminologies: grid computing, cloud computing. Computing power of a single CPU chip • Moore‘s law is the observation that the computing power of CPU doubles approximately every two years. • Nowadays the multi-core technique is the key to keep up with Moore's law. Why computer cluster? • Drawbacks of increasing CPU clock frequency: --- Electric power consumption is proportional to the cubic of CPU clock frequency (ν3). --- Generates more heat. • A drawback of increasing the number of cores within one CPU chip: --- Difficult for heat dissipation. • Computer cluster: connect many computers with high- speed networks. • Currently computer cluster is the best solution to scale up computer power. • Consequently software/programs need to be designed in the manner of parallel computing. Basic structure of a computer cluster • Cluster – a collection of many computers/nodes. • Rack – a closet to hold a bunch of nodes.

  • Applying the Roofline Performance Model to the Intel Xeon Phi Knights Landing Processor
    Applying the Roofline Performance Model to the Intel Xeon Phi Knights Landing Processor Douglas Doerfler, Jack Deslippe, Samuel Williams, Leonid Oliker, Brandon Cook, Thorsten Kurth, Mathieu Lobet, Tareq Malas, Jean-Luc Vay, and Henri Vincenti Lawrence Berkeley National Laboratory {dwdoerf, jrdeslippe, swwilliams, loliker, bgcook, tkurth, mlobet, tmalas, jlvay, hvincenti}@lbl.gov Abstract The Roofline Performance Model is a visually intuitive method used to bound the sustained peak floating-point performance of any given arithmetic kernel on any given processor architecture. In the Roofline, performance is nominally measured in floating-point operations per second as a function of arithmetic intensity (operations per byte of data). In this study we determine the Roofline for the Intel Knights Landing (KNL) processor, determining the sustained peak memory bandwidth and floating-point performance for all levels of the memory hierarchy, in all the different KNL cluster modes. We then determine arithmetic intensity and performance for a suite of application kernels being targeted for the KNL based supercomputer Cori, and make comparisons to current Intel Xeon processors. Cori is the National Energy Research Scientific Computing Center’s (NERSC) next generation supercomputer. Scheduled for deployment mid-2016, it will be one of the earliest and largest KNL deployments in the world. 1 Introduction Moving an application to a new architecture is a challenge, not only in porting of the code, but in tuning and extracting maximum performance. This is especially true with the introduction of the latest manycore and GPU-accelerated architec- tures, as they expose much finer levels of parallelism that can be a challenge for applications to exploit in their current form.

  • Coprocessors: Failures and Successes
    COPROCESSORS : FAILURES AND SUCCESSES APREPRINT Daniel Etiemble Paris Sud University, Computer Science Laboratory (LRI) 91405 Orsay - France [email protected] July 25, 2019 English version of the paper presented in the French Conference COMPAS 2019. ABSTRACT The appearance and disappearance of coprocessors by integration into the CPU, the success or failure of coprocessors are examined by summarizing their characteristics from the mainframes of the 1960s. The coprocessors most particularly reviewed are the IBM 360 and CDC-6600 I/O processors, the Intel 8087 math coprocessor, the Cell processor, the Intel Xeon Phi coprocessors, the GPUs, the FPGAs, and the coprocessors of manycores SW26010 and Pezy SC-2 used in high-ranked supercomputers in the TOP500 or Green500. The conditions for a coprocessor to be viable in the medium or long-term are defined. Keywords Coprocessor · 8087 · Cell · Xeon Phi · GPU 1 Introduction Since the early days of computers, coprocessors have been used to relieve the main processor (CPU) of certain “ancillary” tasks. These coprocessors have been or are being used for different tasks: • I/O coprocessors • Floating-point coprocessors • Graphic coprocessors arXiv:1907.06948v1 [cs.AR] 16 Jul 2019 • Coprocessors for accelerating computation The history of these coprocessors is diverse. Some have disappeared in the medium or short-term, following a technological breakthrough such as the invention of semiconductors, or the evolution of integrated circuit density. This is particularly the case of I/O coprocessors or floating-point coprocessors. Others like graphic coprocessors have a tumultuous history depending on their use for graphics or for high-performance computing or artificial intelligence.
