OpenCL - OpenGL Interop Tutorial

Using OpenCL to manipulate OpenGL objects has important advantages: the GPU is usually faster and data transfer from Host memory to Device memory is kept to a minimum. CMSoft OpenCL/GL interop tutorial shows detailed implementation of circular wave interference simulation using CL/GL interop, including commented source code available for download.

ODE system solving with OpenCL

Differential equations are crucial to all exact sciences, such as engineering, physics, chemistry and even economics. There packages use GPUs to compute solutions to problems such as solving linear systems and computing FFT. This work covers an easy-to-use ordinary differential equation system solver for scientific applications and games. Examples include calculating trajectories and collision of particles in game engines, electron-proton interactions, gravitational calculations, dynamic modeling of deformable bodies and many more.

Khronos Drives Momentum of Parallel Computing Standard with Release of OpenCL 1.1 Specification

The Khronos™ Group today announced the ratification and public release of the OpenCL™ 1.1 specification, the latest version of the open, royalty-free standard for cross-platform, parallel programming of modern processors. OpenCL 1.1 adds significant functionality for enhanced parallel programming flexibility, functionality and performance including:

  • New data types including 3-component vectors and additional image formats;
  • Handling commands from multiple hosts and processing buffers across multiple devices;
  • Operations on regions of a buffer including read, write and copy of 1D, 2D or 3D rectangular regions;
  • Enhanced use of events to drive and control command execution;
  • Additional OpenCL C built-in functions such as integer clamp, shuffle and asynchronous strided copies;
  • Improved OpenGL interoperability through efficient sharing of images and buffers by linking OpenCL and OpenGL events.

OpenCL™ Optimization Case Study: Simple Reductions

AMD Developer central just released an OpenCL optimization case study on SImple Reductions. Strategies examined for efficiently mapping reductions onto the ATI Radeon™ HD 5870 GPU and AMD Phenom™ II X4 965 CPU. Taking advantage of properties of the reduction being performed, as well as matching the style of reduction to the hardware platform, can result in performance improvements of up to 15x, compared to naive code.
