ipp on xeon from Windows: *mic* cannot open source file "ipp.h"

I have a xeon phi coprocessor plugged in Windows computer and I want to test some ipp functions on it, but a target compilation (VS2015 Community) fails with the message: *MIC* cannot open source file "ipp.h".

Btw, ipp.h become available immediately after switching the project to Intel compiler (before I set "Use Intel IPP" to "Single-threaded Static Library" from "No"), maybe it it somehow connected with the problem.

And is it possible at all to run ipp in offloaded mode or the library will be available only in a native app?

Hi!

 

And is it possible at all to run ipp in offloaded mode or the library will be available only in a native app?

It's hardly important to you yet, but yes it's possible to use ipp in offload mode. You can find documentation in the intel parallel studio installiation folder, something like this: "...\compilers_and_libraries\windows\ipp\examples\components_and_examples_mic\components\examples_mic\documentation\".

In short you need to set the following project properties:

  1. Configuration Properties -> c/c++ -> Code Generation [Intel C++] -> Additional Options for MIC Offload Compiler: -I\"$(IPPROOT)\"include, where IPPROOT - environment variable that contains path to IPP (C:\Program Files (x86)\IntelSWTools\compilers_and_libraries_2017\windows\ipp)
  2. Configuration Properties -> Linker -> General [Intel C++] -> Additional Optional for MIC Offload Linker: -L\"$(IPPROOT)\"/lib\intel64_win_mic -lipps -lippcore -lippvm, where with '-L' option you specify where to look for ipp libraries and with '-l' you specify which libraries needs (without 'lib' prefix and extension).

You may not set '-L' property and it will still work.

 

Best regards, Alexander.
