Intel® Integrated Performance Primitives

Announcing new product: Intel® Data Analytics Acceleration Library 2016 Beta

We are pleased to announce the release of Intel® Data Analytics Acceleration Library 2016 Beta! Intel® Data Analytics Acceleration Library is a C++ and Java API library of optimized analytics building blocks for all data analysis stages, from data acquisition to data mining and machine learning. It is a library essential for engineering high performance data application solutions. Click here to see more.




Previous external samples package now legacy

Starting with the release of IPP 8, the product is renewing its focus on primitives (with emerging GPU enablement as demonstrated in IPP's technology preview releases).  Small, simple examples will be the goal instead of large samples.

With the release of IPP 8, all of the large samples previously distributed as an external samples package are now legacy.  This includes 

ippiTranspose crashing


I am calling ippTranspose with the following parameters (and valid buffer pointers of course):

void *pSrc = <input buffer>;
void *pDst = <output buffer>;
int iWidth  = 640;
int iHeight = 480;
int iSrcStep = iWidth * 3;
int iDstStep = iHeight * 3;
int iSrcOffset = iSrcStep * (iHeight - 1);
int iSrcStepT  = -iSrcStep;
IppiSize sizeSrc = { iWidth, iHeight };
ippiTranspose_8u_C3R((Ipp8u*)pSrc + iSrcOffset, iSrcStepT, (Ipp8u*)pDst, iDstStep, sizeSrc);

It crashes here:

Create a LIB File from Intel IPP


I'm using Visual Studio 2013 and the Intel IPP 8.2.

I have some Auxiliary Functions I build upon Intel IPP for image manipulation in C++ style by overloading some operators and defining function which are composition of many Intel IPP functions.

Now, I want to build a library of that functions I created and I want this library to be "Self Defined".
Namely, on my future projects I want to link to that library (And only that) and be able to use my functions (Which relies on Intel IPP).
Basically, it is something like the question here:

IPPM WarpAffine Center

Hi experts,

i want to perform an affine warp of my image. Is there a function which supports warping in respect to the center of the image (and not to the top-left origin of the ROI)? I tried the ippiWarpAffineLinear_32f_C1R for my case but without success.

Any idea? An example would be great :)!

IPP zlib slower than opensource zlib when used by HBase

Hi everyone,

Recently I tried to replace the stock zlib with IPP zlib 7.0.6 on 64-bit Linux in order to boost the performance of a project using HBase 0.99.2. However I observed slowdown in compression performance by about 30%. I measure the time that "deflate" function takes (inside Hadoop native library), and indeed it's slower than stock zlib and the slowdown happens almost all inside "deflate" calls.

IPP Cryptography Library - where are the files as ippcp.h ?

IPP Cryptography Library

The IPP cryptography library files are not included in the above lists, since they are not part of the standard product. If you are using the IPP cryptography library you will need to add those library files to your link list. The crypto files are named ippcp*.

So where are these files ?

i need to to use bignumber but it is impossible because i do not have IPP Cryptography Library ? i precise I bought the product !

thanks for your help
