Opengl 4.3 demo9/14/2023 To produce a set of output records (pixels for the final image) in parallel.ĭue to the parallel execution, each element is processed independently, without any dependencies between elements.Īs stated above the most important (mandatory) aspect of programs running on GPUs is that they must be parallelizable. a fragment Shader) to run over a set of input records/ stream (e.g. Since the GPU is not a serial but a stream processor it's not trivial to program the same algorithms which were designed for the CPU to run on the GPU as well.Ī stream processor uses a function/ kernel (e.g. However, this performance boost comes with a hurdle in programming algorithms. The reason for this purpose change is performance, as GPUs perform floating-point calculations much faster than today's CPUs. While traditionally the graphics card (GPU) has been a rendering co-processor which is handling graphics, it got more and more common to use graphics cards for other (not necessarily graphics related) computational tasks (General Purpose Computing on Graphics Processing Units short: GPGPU-Programming). In this chapter, we will have a look on the compute shader and try to understand how it works and how we can create and run a compute shader.
