For those of you wondering what is the benefit of a CUDA/OpenCL graphics card in your laptop or desktop computer, here is another example of what is possible to do with the GPU processing power:
Mars: A MapReduce Framework on Graphics Processors
Mars is a MapReduce framework on graphic processors (GPUs). We develop this framework aiming at providing a generic framework for developers to implement data- and computation-intensive tasks correctly, efficiently, and easily on the GPU. Mars hides the programming complexity of the GPU behind the simple and familiar MapReduce interface. Therefore, the developers can write their code on the GPU without any knowledge of the graphics APIs or the GPU architecture. We have implemented six common tasks in web applications and our results indicate that Mars is up to over an order of magnitude faster than its CPU-based counterpart for these applications on a quad-core machine.
Mars is developed by Bingsheng He and Wenbin Fang under the supervision of Naga K. Govindaraju (Microsoft Corp.), Qiong Luo (HKUST), and Tuyong Wang (Sina.com).

Currently, Mars is implemented using NVIDIA CUDA.
* Nov 16, 2009: The latest version. This version runs on both 32-bit and 64-bit linux, and supports the latest CUDA SDK 2.3. It includes 8 applications: String Match, Matrix Multiplication, Inverted Index, Word Count, Page View Rank, Page View Count, Similarity Score, and Kmeans.
* Mars_v2.zip: the second version, including experiment data from our PACT08 paper and templates for application development. This version runs on Windows. Aug 2008.
* Mars.zip( ~0.5MB): It includes the implementation of the framework and the six web applications. This version runs on Linux. Nov 25, 2007.
