This two day webinar series introduces you to the world of multicore and manycore computing with Intel® Xeon® processors and Intel® Xeon Phi™ coprocessors. Expert technical teams at Intel discuss development tools, programming models, vectorization, and execution models that will get your development efforts powered up to get the best out of your applications and platforms.
Intel(R) VTune(TM) Amplifier XE supports memory bandwidth analysis on recent Sandbridge, Ivybridge, and Haswell processors. However if the user worked on some old processors, for example – Nehalem, Westmere-DP, will receive error message such as:
# amplxe-cl -collect wsmex-write-bandwidth -duration 10
amplxe: Fatal error: This analysis type is only defined for Intel processors code name Beckton or Eagleton.
Consider the case when you
- Create a FFTW3 plan and use the plan for sequential DFT computation on each thread in your parallel region
- Use Intel Math Kernal Library (Intel MKL) FFTW3 wrappers
- Want the best performance
Intel MKL FFTW3 wrappers are thread safe by default. However, you should set one additional Intel MKL variable to get the best performance with Intel MKL. Set the number_of_users_threads variable as described below.
Download this guide to learn how to identify performance issues on software running on the 4th Generation Intel® Core™ Processor family (based on Intel Haswell microarchitecture). The guide explains how to use Intel® VTune™ Amplifier XE's General Exploration profile for 4th Generation Intel® Core™ Processors. It explains how to identify the most common software performance issues and gives suggestions for how to address each.
