msach@0: Installation:
msach@0: 
msach@0: To install the kernel benchmark, navigate to the directory this file is located in, open up a terminal and simply type 'make'. For certain architectures

msach@0: Usage:
msach@0: 
msach@0: You may execute the benchmark by navigating to this directory after compilation and typing
msach@0: 
msach@0: ./c-ray-mt -i FILENAME -s RESOLUTION -o OUTPUT.ppm 
msach@0: 
msach@0: 'FILENAME' has to be either "scene" or "sphfract" or another predefined scene description file if there is one.
msach@0: 'RESOLUTION' specifies the resolution of the produced image and has to be given in the form 1920x1200, for example.
msach@0: 'OUTPUT' is the name of the file the rendered image will be contained in after the benchmark ran.
msach@0: 
msach@0: The specification of how many threads are used to perform the rendering depends on the parallel programming model.
