Many-core computing devices have large numbers of processors (cores) on a single chip. Such configurations are attractive because they can achieve a greater performance (calculations per second) for a given amount of electrical power than their single-core cousins. CPUs are heading down this route with dual-core and quad-core processors now commonplace. However, accelerator add-on cards or chips are also available today which have over 100 cores; of these, the graphics processing unit (GPU) is the most widespread.
many-core.group is a site where researchers at Cambridge University who are using many-core devices to accelerate their scientific applications can show their results and describe their experiences.
