  1. 24. Introduction - Lecture 1
    Mr Sverre Jarp (CERN)
    16/06/2014, 11:45
    In this lecture we start by discussing Moore’s law which has led to an incredible transistor count becoming available for hardware designers. As a result, modern microprocessors have a high level of complexity and an unprecedented level of parallelism that software programmers are asked to exploit. We define the seven dimensions of performance which will be discussed during the week. The...

  2. 25. Advanced Performance Tuning - Lecture 2
    Andrzej Nowak (CERN)

    Benchmarking and performance tuning rarely are first-rate activities. However, the importance of both is on the rise following the trends in hardware related to Moore’s Law. In this lecture we will explain advanced aspects of performance benchmarking, monitoring and tuning. The presented methodologies and techniques will be supported by practical information, including compiler examples....

  5. 48. Floating Point Programming - Lecture 4
    Mr Sverre Jarp (CERN)
    17/06/2014, 11:45
    We start by asked ourselves why we need to bother about this topic at all. Hopefully, having convinced ourselves, we then discuss the IEEE-754 standard which is used in all modern microprocessors. We discuss several techniques for keeping floating-point calculations accurate. Math functions, such as exponentials and power functions, are also invoked, since they can be costly in performance and...
