Mandelbrot Design Example

This example provides a kernel that implements the Mandelbrot fractal algorithm as well as a host application that displays the results to the screen. The host application is interactive and allows you to move and zoom around the region.

This example also enables increased performance by supporting execution on multiple Open Computing Language (OpenCLTM) devices. In this example, the problem is divided across multiple devices by partitioning the rows to be rendered.

Features

  • Multiple device partitioning
  • Visual and interactive host application

Downloads

The design example provides source code for the OpenCL device (.cl) as well as the host application. For compiling the host application, the Linux package includes a Makefile and the Windows package includes a Microsoft Visual Studio 2010 project.
