Title:
ブートアップ速度を向上させる方法
Document Type and Number:
Japanese Patent JP2007526556
Kind Code:
A
Abstract:
There is provided a method of increasing boot-up speed in a computer system ( 10 ). The system ( 10 ) includes computing devices ( 20 ) for processing data and a data store ( 60 ) coupled thereto for providing data to and receiving data from the devices ( 20 ). The store ( 60 ) is operable to write and/or read data in several regions (T 1 , T 2 , T 3 ) of a data medium ( 200 ). Access between the regions is subject to associated jump delays (SK 1/2 , SK 2/3 ; SK 1/3 , SL 3/2 ). The store ( 60 ) includes a cache ( 320 ) for temporarily storing data read from and/or for writing data to the medium ( 200 ). On initial boot-up of the system ( 20 ), a log is made of a sequence in which the regions (T 1 , T 2 , T 3 ) are accessed. Moreover, on subsequent boot-up of the system ( 10 ), the log is used to store data read from the medium ( 200 ) temporarily in the cache ( 310, 320 ) so as to provide for a more temporally efficient sequence of accessing the regions (T 1 , T 2 , T 3 ) for speeding up said subsequent boot-up.
