due to the increasing computing power of each generation of game consoles, a novel use has emerged where they are repurposed into high-performance computing (hpc) clusters. some examples of game console clusters are sony playstation clusters and microsoft xbox clusters. another example of consumer game product is the nvidia tesla personal supercomputer workstation, which uses multiple graphics accelerator processor chips. besides game consoles, high-end graphics cards too can be used instead. the use of graphics cards (or rather their gpu's) to do calculations for grid computing is vastly more economical than using cpu's, despite being less precise. however, when using double-precision values, they become as precise to work with as cpu's and are still much less costly (purchase cost).
