High CPU usage when 2 application use IPP

$

Hi,

I am running 2 applications which use IPP for decoding and image processing. When I run both the applications together the CPU usage of the application which does decoding increases. But when I stop the second application(image processing) then CPU usage of first application decreases.

For example-

 - There are 2 applications A and B.

 - When I run A application only then CPU usage of A is X%.

 - When I start B application also then CPU usage of A increases(X+w)%.

My platform is Linux(Debian).

What can be the reason that if I run B then CPU usage of A increases?
