DPS915 Presentation Ray Tracing Parallelization Soutrik Barua • Faiq Malik
Assignment Assignment 1 Sudoku Breakdown ● Ray Tracing ● Assignment 2 Porting code for CUDA ● CPU vs CPU+GPU execution times ● Assignment 3 Further optimization ● Final analysis and conclusion ●
What is Ray Tracing? Ray Tracing Rendering Technique for generating an ● image by tracing the path of light. Simulating the effects of its trajectory ● path with virtual objects. Practical applications To calculate and simulate path of ● particles and waves. Optical Lens Design ○ Acoustics ○ Radio Signal Propagation ○ Astrophysics ○ many more ○
Progress Accomplishments Optimized code for CUDA enabled device ● Decreased run time ● Enhanced image processing speed ●
GPU runtimes by Image Resolution Image Resolution at 512 Image Resolution at 1024 Image Resolution at 2048 Image Resolution at 4096
CPU vs GPU
Potential Ways to Optimize Further ● Use more available bandwidth ● Have better memcpy efficiency ● Better compute overlap ● More use of cores depending on GPU/compute capability ● Reduce memory access times.
