PURPOSE:To reduce the load of each host processor and to make the management of system effective, by managing the access control to a file of each host processor, and managing the busy state of the file at each node processor. CONSTITUTION:Host processors 1-1-1-n are connected via node processors 2 respectively and among the processors 1-1-1-n and the node processor 2, correspondence is done via packet transmission and reception interfaces 6, 7. The data format in this case is taken as a data packet format 12 and the processors 1-1-1-n manage the access control to the files 3-11 and 3-12. An RAM 10 of the node processor 2 is provided with a busy state managing table 11 managing the busy state, and the busy state of the files 3-11 and 3-12 of the processors 1-1- 1-n to reduce the load of the processors 1-1-1-n. |
