| msach@0 | 1 Kernel: Ray Tracing |
| msach@0 | 2 |
| msach@0 | 3 This is a kernel-type benchmark of a very simple and brute-force ray tracer. |
| msach@0 | 4 |
| msach@0 | 5 Installation: |
| msach@0 | 6 |
| msach@0 | 7 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 | 8 or special compilation options, you might need to change compilation parameters in the makefile. |
| msach@0 | 9 |
| msach@0 | 10 Usage: |
| msach@0 | 11 |
| msach@0 | 12 You may execute the benchmark by navigating to this directory after compilation and typing |
| msach@0 | 13 |
| msach@0 | 14 ./c-ray-mt -i FILENAME -s RESOLUTION -o OUTPUT.ppm |
| msach@0 | 15 |
| msach@0 | 16 'FILENAME' has to be either "scene" or "sphfract" or another predefined scene description file if there is one. |
| msach@0 | 17 'RESOLUTION' specifies the resolution of the produced image and has to be given in the form 1920x1200, for example. |
| msach@0 | 18 'OUTPUT' is the name of the file the rendered image will be contained in after the benchmark ran. |
| msach@0 | 19 |
| msach@0 | 20 The specification of how many threads are used to perform the rendering depends on the parallel programming model. |
