Distributed computing system and resource allocation method

Abstract

In a distributed computing system, a bottleneck for performance of a network is avoided and a high-performance scalable resource management function is achieved. The distributed computing system includes a plurality of components connected to each other via a network. Each of the components includes a plurality of compute nodes, a plurality of drive casings, and a plurality of storage devices. The network includes a plurality of network switches and is configured in layers. When a storage region is to be allocated to a compute node among the compute nodes, a managing unit selects, from the storage devices, a storage device related to the storage region to be allocated or selects, from the drives, a drive casing related to the storage region to be allocated, based on a network distance between two of the compute node, the storage device, and the drive casing.
