ABSTRACT:
A disk access apparatus for performing a stride processing of data is used in a parallel computer system for connecting a plurality of computers to each other through a network. The disk access apparatus comprises a first data storage unit for storing stride process object data which is an object of a data distribution or data merging operation, a stride data storing position storage unit for storing the data storing position in the first data storing unit or a pointer designating a header of a packet of the object data transmitted from another data storage unit, a second data storage unit for storing the stride object data, a stride data storing destination storage unit for storing a data storing position in the second data storage unit or a pointer designating a header of a packet to be transmitted to another computer when stride object data is included in the packet, a partial data size storage unit for storing a size of the partial data which is an object of the distribution or a merging operation, and a stride processing unit for storing the stride process object data designated by the storing content in the stride data storing position storage unit in accordance with the content stored in the stride data storing destination storage unit in a merging or distributing manner in response to a data read or write command by using the data size stored in the partial data size storage unit.
