Title:
INFORMATION PROCESSING DEVICE, INFORMATION PROCESSING METHOD, AND INFORMATION PROCESSING PROGRAM
Document Type and Number:
WIPO Patent Application WO/2014/103037
Kind Code:
A1
Abstract:
An objective of the present invention is, in one aspect, to improve response performance in an information processing system. A monitoring daemon program (62) receives a user's I/O load condition (56) (Pa), generates an I/O load pattern, imparts I/O load with an external command (58) (Pb, Pc), and acquires I/O response time from an I/O monitoring driver (68). I/O time-out time is derived from the I/O response time and set. The I/O monitoring driver (68) monitors the I/O from an I/O request to a response from a disk driver (72) (Pd-Pf, Pj). The monitoring daemon program (62) acquires I/O load information at an operating stage from the I/O monitoring driver (68), derives the I/O time-out time, and notifies the I/O monitoring driver (68), whereby the I/O time-out time is updated (Ph), thus becoming the I/O time-out time according to a change of the I/O load.
