#### DirectCompute tutorial for Unity: Introduction

I’ve been using Unity for about 2 years now but before then I use to write my programs in C++ and manually create a graphics context to work with. 1,252 more words

#### Correctly enabling cl_khr_fp64 in both OpenCL 1.1 and 1.2

I started most of my OpenCL development on Nvidia GPUs, which still only support OpenCL 1.1. When I started testing code that used double precision arithmetic on AMD Radeon GPUs, I kept running into a warning about the cl_khr_fp64 extension. 396 more words

Fast Poisson Solvers for Graphics Processing Units

Two block cyclic reduction linear system solvers are considered and implemented using the OpenCL framework. The topics of interest include a simplified scalar cyclic reduction tridiagonal system solver and the impact of increasing the radix-number of the algorithm. 103 more words

#### GPGPU hacking on the Pi

Update: As Andrew mentions in the comments below, we recently made the source for Andrew Holme’s accelerated FFT library available. I’d encourage aspiring Pi GPGPU hackers to take a look at this – it’s an incredibly tight piece of code. 155 more words
