Abstract: PROBLEM TO BE SOLVED: To section respective data processing subsystems without connecting or disconnecting any process node by allowing a constitution utility resident on a data storage device to constitute multiple process nodes selectively into a single NUMA system or multiple independent data processing systems. SOLUTION: To a data processing system, multiple process nodes 8 are connected. The respective process nodes 8 are accessed by a system memory 18 through processors 10a to 10m, a local interconnection 16, and a memory controller 17. At this time, the process nodes are constituted selectively into a single NUMA(non-uniform memory access) system or independent data processing systems. Consequently, the respective data processing subsystems can be sectioned without connecting or disconnecting any process node 8.
