There's no memory leak problem that I can detect, everything is initialized. </P> <P>Is there a possibility that the routine optzAdd2 can only be optimized locally ? </P> <P>Are there any users who have had similar experienes with the routines from signal processing library ? </P> <P>Many thanks in advance, </P> <P>Patricia Astrid</P> Fri, 06 Oct 2006 17:19:37 GMT Anonymous32 2006-10-06T17:19:37Z https://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/Debug-vs-Release-differences-when-using-optzAdd2-for-from/m-p/907181#M11807 <P>Dear forum,</P> <P>I found differences between the calculations resulted from optzAdd2.for from Intel Signal Processing library. </P> <P>If I turn on the global optimization, optimize for speed, or full optimization then the release version sometimes deviate quite significantly from the debug version.
