The Slurm Workload Manager (formally known as Simple Linux Utility for Resource Management (SLURM)), or Slurm for short, is a free and open-source job scheduler for the Linux kernel used by many of the world's supercomputers and computer clusters. It provides three key functions. First, it allocates exclusive and/or non-exclusive access to resources (computer nodes) to users for some duration of time so they can perform work. Second, it provides a framework for starting, executing, and monitoring work (typically a parallel job such as MPI) on a set of allocated nodes. Finally, it arbitrates contention for resources by managing a queue of pending jobs. Slurm is the workload manager on about 60% of the TOP500 supercomputers, including Tianhe-2 that () is the world's fastest computer. Slurm uses a best fit algorithm based on Hilbert curve scheduling or fat tree network topology in order to optimize locality of task assignments on parallel computers. ==History== Slurm began development as a collaborative effort primarily by Lawrence Livermore National Laboratory, SchedMD, Linux NetworX, Hewlett-Packard, and Groupe Bull as a Free Software resource manager. It was inspired by the closed source Quadrics RMS and shares a similar syntax. Over 100 people around the world have contributed to the project. It has since evolved into a sophisticated batch scheduler capable of satisfying the requirements of many large computer centers. , TOP500 list of most powerful computers in the world indicates that Slurm is the workload manager on six of the top ten systems. Some of the systems in the top ten running Slurm include Tianhe-2, a 33.86 PetaFlop system at NUDT, IBM Sequoia, an IBM Bluegene/Q with 1.57 million cores and 17.2 Petaflops at Lawrence Livermore National Laboratory; Piz Daint a 7.78 PetaFlop Cray computer at Swiss National Supercomputing Centre, Stampede, a 5.17 PetaFlop Dell computer at the Texas Advance Computing Center; and Vulcan, a 4.29 Petaflop IBM Bluegene/Q at Lawrence Livermore National Laboratory;. 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「Slurm Workload Manager」の詳細全文を読む スポンサード リンク
