Update – source code now available

Microsoft have recently released a beta of Silverlight 4, which has limited support for native interoperation using COM. Potentially, this example could be applied to any number of native interop scenarios, however for this example I have chosen to use Nvidia’s CUDA technology.

Disclaimer : This is an example of what can be done, not necessarily, and in all likelihood, an example of how it should be done.

About CUDA

Up until around 2001 PC graphics cards, though powerful, implemented a fixed function pipeline that limited use to whatever was exposed by the APIs, usually Direct3D or OpenGL. The addition of a programmable pixel pipeline led to the use of graphics cards for more general computation tasks; at first using shaders directly, followed by higher level GPU specific programming languages, such as Brook, SH, and later NVidia’s CUDA. Most of this work was, and is, documented by the GPGPU group. NVIDIA’s website shows CUDA being used in a wide variety of applications but in practice it is best employed in so called “embarassingly parallel” problems.

I sometimes find it useful to search MSDN directly using Google, so I wrote a search plugin using OpenSearch to make this easier. Firefox should discover the search plugin automatically – it should appear in the search drop down at the top right. Otherwise, you can just install the plugin directly. For more details, see Creating OpenSearch plugins for Firefox.

Silverlight 3.0 moved its featureset closer to that of WPF by adding support for merged Resource Dictionaries and Style Inheritance. Without these features, developing custom templates and styles for Silverlight controls can become a bit of a copy-and-paste nightmare. Since I have used the implicit theming feature built into the Silverlight Toolkit to make my Silverlight controls fit into the overall look and feel of this site, I was hoping that these features would enable me to refactor my themes developed for Silverlight 2.0 to be a bit less unwieldy.
