Questions related to Intel Integrated Performance Primitives (IPP), a multi-threaded library of functions for multimedia and data-processing applications.

Intel Integrated Performance Primitives (Intel IPP) is an extensive library of "algorithmic building blocks" for multimedia, data-processing, and communications applications. It supports multiple threads and has been highly optimized for Intel-family microprocessors, making extensive use of SIMD instructions (e.g., MMX, SSE, and AVX). The Windows, Linux, Android, and macOS environments are supported.

The library supports a wide range of functions for various domains and also provides for an OpenMP configuration, which can allow certain functions to run on multiple cores.

Using OpenCV Mat images with Intel IPP?

I've recently started using Intel Performance Primitives (IPP) for image processing. For those who haven't heard of IPP, think of IPP as the analogue of MKL for image processing instead of linear algebra. I've already implemented a somewhat…

How do I get rid of LD_LIBRARY_PATH at run-time?

I am building a C++ application that uses Intel's IPP library. This library is installed by default in /opt and requires you to set LD_LIBRARY_PATH both for compiling and for running your software (if you choose the shared library linking, which I…

Recommendations on how to evaluate openCV with Intel's Integrated Performance Primitives?

We have a fair amount of openCV code, and we plan on investigating Intel's IPP, and seeing what kind of speed ups we can achieve in our application. Intel has a white paper on how to link OpenCV and IPP. Using Intel IPP with OpenCV It looks like…

Can/should libiomp5 and libgomp mix?

We are compiling an application that uses OpenMP. We are using gcc 4.4, with -fopenmp. The app also uses IPP, which includes its own version of OpenMP (libiomp5). (Note: we are disabling IPP's internal threading by calling ippSetNumThread(1). …

How to disable parallelism in OpenCV?

I've built OpenCV using Intel IPP, so I suppose that whenever possible it's used (e.g. matrix multiplication). I want to test the scalability of my parallel application by comparing it with a serial version. In order to do so, when it I…
