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.
This webinar focuses on the Intel System Studio components that can be used to implement signal processing workloads. The webinar complements the previous “tools of the embedded trade” webinars on Intel® VTune™ Amplifier, Intel® Inspector, Intel® JTAG Debugger, and other process-oriented features (e.g. cross-compilation). We provide a case study to familiarize you with the signal processing functionality of Intel System Studio and cover the following components:
Intel® Math Kernel Library (Intel® MKL) includes the optimized DFT transform functions on Intel® Xeon Phi™ coprocessors. These functions are carefully vectorized and threaded to take advantage of the hardware features. This article provides some performance tuning tips on running MKL DFT function on Intel Xeon Phi coprocessors. We will start with some simple example code.
