Distributed computing system and resource allocation method

A resource allocation method of a distributed computing system including a plurality of components connected to each other via a network, wherein

• each of the components includes
• a plurality of compute nodes that activate an application and issue an input and output request to input and output data on the application,
• a plurality of drives that physically store the data to be input and output in accordance with the input and output request, and
• a plurality of storage devices that execute a process on the data to be input to and output from the drives,
• the network has a plurality of network switches and is configured in layers, and
• upon allocating a storage region to a compute node among the compute nodes, a managing unit selects one of a storage device related to the storage region to be allocated and a drive 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,
• wherein the network distance is determined based on the number of network switches via which data is transferred between the compute node and the storage device or the drive.
