Hello dbricker,
I want to know
-what does this VTuneDemo application do
-what are the performance bottlenecks it have
-any demo application might be having some demonistration objectives or goals. So I want to know what are the demonistration objectives/goals on which the VTuneDemo has been prepared...?

Prasad.

VTuneDemo application demonstrates VTune ability to find bottleneck using all available in VTune profiling methods.

The application contains 4 routines:
test_if - simple matrix operations that use global variable
test_if1 - the same as test_if, but use of local variable instead of global
test_memset - demonstrates, that manually written memset has performance problems, so it better to use memset from "C" runtime library
divd_rout - floating point division - bottleneck of the application

Those routines are run hundreds of times with independent time measurement. Timing results are displayed in the output window.
