Just how to Write Fast Code

Fundamental Information

The quick development and increasing complexity of computing platforms pose a significant challenge for designers of high end pc pc software for engineering, technology, and customer applications: it becomes increasingly harder to harness the available computing energy. Simple implementations may lose up to a couple of purchases of magnitude in performance. On the other hand, producing implementations that are optimal the designer to own an awareness of algorithms, abilities and limits of compilers, while the target platform’s architecture and microarchitecture. This course that is interdisciplinary the pupil towards the foundations and advanced approaches to high end computer pc computer software development utilizing essential functionality such as linear algebra kernels, transforms, filters, among others as examples. The program will explain exactly how to optimize when it comes to memory hierarchy, benefit from unique instruction sets, and exactly how to publish code that is multithreaded multicore platforms, according to advanced research. Further, a strategy that is general performance analysis and optimization is introduced that the pupils will use in team jobs that accompany the program. Finally, the program will introduce the pupils towards the field that is recent of performance tuning.

The program will build upon but expand the version taught in Spring 2005.

Topics Covered

  • Algorithm analysis: Problem versus algorithm, complexity and value (asymptotic, exact, calculated), O-calculus, algorithms in posting
  • Computer architecture (a pc software standpoint): architecture and microarchitecture, memory hierarchy, unique instruction sets, multicore platforms
  • Compilers: skills, limits, just how to utilize
  • Efficiency optimization: help guide to benchmarking, finding hotspots, rule analysis, performance optimization techniques (for memory hierarchy, making use of vector guidelines, composing multithreaded code); these methods are examined utilising the examples into the bullet that is next
  • Numerical functionality examined in more detail (complexity interesting persuasive speech topics, algorithms, how exactly to compose greatest performance rule): linear algebra kernels, transforms, filters, sparse linear algebra, sorting, other people, your quest task
  • State-of-the-art research in automated Efficiency Tuning: ATLAS, LAPACK, BeBOP, FFTW, SPIRAL, other people

Objectives with this Program

  • Discover a guideline how exactly to compose quick numerical code and put it on in homeworks as well as your research project
  • Comprehend the connection between algorithms, implementations, and computer architecture
  • Discover some fundamental numerical algorithms
  • Discover ways to evaluate numerical algorithms

There is absolutely no textbook because of this course. A few of this tutorial is followed by the material.

The component this is certainly foundation (algorithms, computer architecture etc.) is going to be put together from several standard publications. The core component, which analyzes cutting side implementations for numerical dilemmas is put together from research documents, the teacher’s own experience.
