<p>PURPOSE:To improve input/output performance by dividing a buffer area for file input/output into areas by purposes including buffer areas for system data and user data, independently managing the respective areas, and controlling the possession and release of a requested buffer. CONSTITUTION:Concerning the file system for a computer system provided with a central processing unit, main storage device and second-order storage device 20, a buffer area 18 for file input/output is initialized by a buffer area initialize processing part 15 and constituted so as to be divided into the plural areas by purposes such as a buffer area 18S for system data and a buffer area 18U for user data at this time of initializing. A buffer management processing part 14 independently manages the respective areas, and a buffer block possession processing part 16 and a buffer block release processing part 17 controls the possession and release of the requested buffer. Thus, input/output processing can be accelerated by utilizing the buffer for a parallel computer system or the like.</p> |
