Problem of maximum CPU usage while executing C++ code which uses IPP

Hi..

I am executing a C++ code implemented using IPP,for compression and decompression of jp2k file format. While executing code on linux CPU usage is 100% but same is 50% on Windows.

Can any body tell me why is it so and how to reduce it on Linux platform?

thanx in advance...

Hello,

well, let's go deeper in the details.

- What version of IPP do you use?
- What is your linkage model on Windows (DLL? static libraries?). Is that the same on Linux?
- Do you use IPP sample or it is your modified code? Is it the same between Windows and Linux?
- What compiler do you use (Intel? Microsoft/gcc?)
- What is your hardware platform on Windows? What about Linux?

Regards,
Vladimir

What are the changes you are talking about? Did not you use original IPP sample? Can you reproduce that issue with original IPP sample?
