The 13 application areas where OpenCL and CUDA can be used

Did you find your specialism in the list? The formula is the easiest introduction to GPGPU I could think of, including the need of auto-tuning.

Which algorithms map is best to which accelerator? In other words: What kind of algorithms are faster when using accelerators and OpenCL/CUDA?

Professor Wu Feng and his group from VirginiaTech took a close look at which types of algorithms were a good fit for vector-processors. This resulted in a document: “The 13 (computational) dwarves of OpenCL” (2011). It became an important document here in StreamHPC, as it gave a good starting point for investigating new problem spaces.

The document is inspired by Phil Colella, who identified seven numerical methods that are important for science and engineering. He named “dwarves” these algorithmic methods. With 6 more application areas in which GPUs and other vector-accelerated processors did well, the list was completed.

As a funny side-note, in Brothers Grimm’s “Snow White” there were 7 dwarves and in Tolkien’s “The Hobbit” there were 13.
