  1. OpenCL Programming for the CUDA Architechture OpenCL Particle System

  2. What I want to do! • Particle System • Application • Library-file • Real-Time, with a decent amount of particles • 30k+, 9800GTX • Adjustable values

  3. Inspirations 2 1 3

  4. Problems • Performance • OpenCL: big difference in performance • 1/7 of the excution time by avoiding classic misstakes. • Important: know the architecture!

  5. GPU Computing • Highly Multithreaded • Reduced vs. Hidden Latency when accessing off-chip memory • High Arithmetic Throughput • GPUs devotes more transistors to arithmetic units • High Memory Bandwidth • = good for particles

  6. Questions?
