INK (for I/O Node Kernel) is the operating system that runs on the input output nodes of the IBM Blue Gene supercomputer.〔''Euro-Par 2004 Parallel Processing: 10th International Euro-Par Conference'' 2004, by Marco Danelutto, Marco Vanneschi and Domenico Laforenza ISBN 3-540-22924-8 pages 835〕〔''Euro-Par 2006 Parallel Processing: 12th International Euro-Par Conference'', 2006, by Wolfgang E. Nagel, Wolfgang V. Walter and Wolfgang Lehner ISBN 3-540-37783-2 page〕 INK is a Linux-derivative.〔 * The compute nodes of the Blue Gene family of supercomputers run CNK (for Compute Node Kernel), a lightweight kernel that runs on each node and supports a single application running for a single user on that node. For the sake of efficient operation, the design of CNK was kept simple and minimal, and it was implemented in about 5,000 lines of C++ code.〔 Physical memory is statically mapped and the CNK neither needs nor provides scheduling or context switching, given that at each point it runs a single application for a single user.〔 By not allowing virtual memory or multi-tasking, the design of CNK aimed to devote as many cycles as possible to application processing.〔 CNK does not even implement file I/O on the compute node, but delegates that to dedicated I/O nodes.〔 * The I/O nodes of the Blue Gene family of supercomputers run INK (for I/O Node Kernel).〔 INK is based on a modified Linux kernel. ==See also== * Compute Node Linux * Timeline of operating systems * Rocks Cluster Distribution * Cray Linux Environment 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「INK (operating system)」の詳細全文を読む スポンサード リンク
