The considerable computing capability of the PlayStation 3's ''Cell'' microprocessors has raised interest in using multiple, networked PS3s for various tasks that require affordable high-performance computing. == PS3 clusters == The National Center for Supercomputing Applications had already built a cluster based on the PlayStation 2.〔(【引用サイトリンク】 title= Scientific Computing on the Sony PlayStation 2 )〕 Terra Soft Solutions has a version of Yellow Dog Linux for the PlayStation 3,〔(【引用サイトリンク】 title= Terra Soft to Provide Linux for PLAYSTATION 3 )〕 and sells PS3s with Linux pre-installed,〔(【引用サイトリンク】 title= Linux pre-installed on PS3 )〕 in single units, and 8 and 32 node clusters.〔(【引用サイトリンク】 title= Linux clusters )〕 In addition, RapidMind is pushing their stream programming package for the PS3.〔(【引用サイトリンク】 title= RapidMind and Terra Soft partner to unleash PlayStation 3 for Linux )〕 On January 3, 2007, Dr. Frank Mueller, Associate Professor of Computer Science at North Carolina State University, clustered 8 PS3s. Mueller commented that the 256 MB of system RAM is a limitation for this particular application, and is considering attempting to retrofit more RAM. Software includes: Fedora Core 5 Linux ppc64, MPICH2, OpenMP v2.5, GNU Compiler Collection and CellSDK 1.1.〔(【引用サイトリンク】 title= Engineer Creates First Academic Playstation 3 Computing Cluster )〕〔(【引用サイトリンク】 title= NC State Engineer Creates First Academic Playstation 3 Computing Cluster )〕〔(【引用サイトリンク】 title= Sony PS3 Cluster (IBM Cell BE) )〕 In Summer 2007, Gaurav Khanna, a professor in the Physics Department of the University of Massachusetts Dartmouth independently built a message-passing based cluster using 8 PS3s running Fedora Linux. This cluster was built with support from Sony Computer Entertainment and was the first such cluster that generated published scientific results. Dubbed as the "PS3 Gravity Grid", this PS3 cluster performs astrophysical simulations of large supermassive black holes capturing smaller compact objects.〔(【引用サイトリンク】 title= PS3 Gravity Grid )〕 Khanna claims that the cluster's performance exceeds that of a 100+ Intel Xeon core based traditional Linux cluster on his simulations. The PS3 Gravity Grid gathered significant media attention through 2007, 2008, 2009 and 2010. Khanna also created a DIY website〔(【引用サイトリンク】 title= PS3Cluster.Org )〕 on how to build such clusters, accessible to the general public. In November 2010 the Air Force Research Laboratory created a powerful supercomputer by connecting together 1,760 Sony PS3s which include 168 separate graphical processing units and 84 coordinating servers in a parallel array capable of performing 500 trillion floating-point operations per second (500 TFLOPS). As built the Condor Cluster was the 33rd largest supercomputer in the world and would be used to analyse high definition satellite imagery. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「PlayStation 3 cluster」の詳細全文を読む スポンサード リンク
