FilterLaplace generates different results when running the 32-Bit vs. 64-Bit

We have observed different results when running the FilterLaplace function between the 32-bit and the 64-bit version of the IPP libraries.
Specifically we are calling: ippiFilterLaplace_8u_AC4R with both 3X3 and 5X5 kernels.
The binary results differ between the 32 and 64 bit libraries.  Is this expected?  We are currently running IPP 7.0.

Many thanks,

Brian

ippsDotProd_32f Performance on Haswell CPU

Hi,

at the moment I'm using ippsDotProd_32f in IPP 7.0 quite extensively in one of my projects. I now tested IPP 8.2 on a Haswell CPU (Xeon e5-2650 v3 in a HP z640 workstation) with this project because I expected it to be significantly faster (see below). Actually, the code was about 10% slower using IPP 8.2 which I found quite disturbing.
