Tianhe-1A, the supercomputer at the National Supercomputer Center in Tianjin, China which in October 2010 became the world's fastest supercomputer, uses what operating system?
Supercomputer operating systems best fit algorithm, and performs Hilbert curve scheduling to optimize locality of task assignments. Several modern supercomputers such as the Tianhe-2 use Slurm, which arbitrates contention for resources across the system. Slurm is open source, Linux-based, very scalable, and can manage thousands of nodes in a computer cluster with a sustained throughput of over 100,000 jobs per hour. Supercomputer operating systems Since the end of the 20th century, supercomputer operating systems have undergone major transformations, as fundamental changes have occurred in supercomputer architecture. While early operating systems were custom tailored to each supercomputer to gain speed, the trend has been
Tianhe-1 Tianhe-1 Tianhe-I, Tianhe-1, or TH-1 (, ; "Sky River Number One") is a supercomputer capable of an Rmax (maximum range) of 2.5 petaFLOPS. Located at the National Supercomputing Center of Tianjin, China, it was the fastest computer in the world from October 2010 to June 2011 and is one of the few petascale supercomputers in the world. In October 2010, an upgraded version of the machine (Tianhe-1A) overtook ORNL's Jaguar to become the world's fastest supercomputer, with a peak computing rate of 2.57 petaFLOPS. In June 2011 the Tianhe-1A was overtaken by the K computer as the world's fastest supercomputer,
