==== Image Profiling Processor Application ====Chosen to profile image profiling processing as shown here: http://www.dreamincode.net/forums/topic/76816-image-processing-tutorial/ , using the sample program files(main/image.h/image.cpp), where it processeses PGM(portable gray map) files.
pulled PGM sample files from here: https://userpages.umbc.edu/~rostamia/2003-09-math625/images.html
rotateKernel<<<dGrid, dBlock >>>(d_a, d_b, rows, cols, sin1, cos1);
The graph below shows the pronounced difference between the sincosf() kernel method and the cpu different sin() cos() method for the 5times larger picturemethods.

There may be other variables that could be moved outside the kernel like r0 and c0, but due to time limitations they weren't tested.
