HOW Series “Deep Dive”: Webinars on Performance Optimization – 2017 Edition

June 30, 2017

Register Why Attend Roadmap Instructor Prerequisites Cluster Materials Software Book Chat   In a Nutshell HOW Series “Deep Dive” is a free Web-based training on parallel programming and performance optimization on Intel architecture. The workshop includes 20 hours of instruction and up to 2 weeks of remote access to dedicated training servers for hands-on exercises. This training is free to everyone thanks to Intel’s sponsorship.   You can get trained in one of the two ways: Self-paced: Start Right Now You can access the video recordings of lectures, slides of presentations and code of practical exercises on this page using a free Colfax Research account. This option is free and open to everyone, however, self-paced study does not give you the benefits that you get by joining a workshop (which is also free, but tied to specific dates).

Dunham has taught physics for 34 years at Middlebury College in Middlebury, Vermont, where he is now William R. Kenan Jr. Professor of Natural Sciences. He currently conducts experimental research in nonlinear dynamics. He is using HPC techniques at the workstation level to analyze large data sets from experiments that can be performed in a small-college laboratory. He received the Bachelor of Science degree in physics from the University of Washington in 1975 and the Ph.D. in physics from Stanford University in 1981. Presentation Savitzky-Golay Filter Algorithm for Large One-Dimensional Data Sets A chaotic pendulum experiment in our laboratory performs about 275 million digitized angle measurements in a 24-hour day. A Poincaré plot of the raw data shows significant and unacceptable discretization effects from the optical rotary encoder used to measure angle. The raw data is therefore passed through a Savitzky-Golay (SG) filter [...]

Webinar: Demystifying Vectorization

May 18, 2017

Free Webinar Abstract Have you heard of code vectorization, but not sure how it applies to your work? Rest assured, you are in a good company. Furthermore, even seasoned computing professionals have a good excuse for not being familiar with this concept! That said, now is a great time to learn about writing vectorized code. That is because in modern Intel processors, vector instructions may speed up arithmetic instructions by up to a factor of 16. However, you must design computational code in a way that makes vector processing possible. In this 1-hour webinar I will explain what to expect from vectorization, and how to make sure that your code has it: Manual and compiler-assisted vectorization Assessing your success with vectorization Loop was vectorized – what’s next? Speaker Andrey Vladimirov, Head of HPC Research, Colfax International Dr. Andrey Vladimirov’s primary research interest is the application of modern computing technologies to computationally demanding scientific problems. Prior to joining Colfax, Andrey was involved in theoretical astrophysics [...]
