Abstract

PURPOSE:To perform the high speed processing by performing input/output processings of data of one file on plural physical mediums in parallel. CONSTITUTION:File data 1a to 3a of one file are distributedly arranged on disks 1 to 3 different in channel. The input/output instruction from a user program 12 is analyzed by a parallel input/output management function 11; and when data is distributedly arranged, input/output processings are simultaneously performed in parallel, and data are composed or decomposed and are transferred to the user program 12. The time of physical input/output for an external disk device is shortened as the whole because of parallel input/output processings of the file, and the high speed processing is possible.

ル管理機能に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to high-speed data input/output processing in systems that require high-speed processing, and in particular to disk drives and y! This invention relates to a file management function that performs high-speed input/output with t (magnetic disk, electronic disk).

〔従来の技術〕[Conventional technology]

従来、上記のような入出力管理機能では並列処理はなく
、直列入出力管理のみが実用されている。Conventionally, the input/output management function described above does not include parallel processing, and only serial input/output management has been put into practical use.

〔発明が解決しようとする課題〕[Problem to be solved by the invention]

上述した従来の入出力管理方式では、ディスク装置上の
データを１ブロツクずつ順番にしか読む事ができない。In the conventional input/output management method described above, data on a disk device can only be read one block at a time.

したがって高速処理を要求されるシステムにおいては、
この物理的な入出力時間（４０ｍ　ｓ　／、　ｉ　ｏ程
度）がネックとなり、ｃｐｕだけをどんなに早くしても
あまり効果がでない欠点がある。Therefore, in systems that require high-speed processing,
This physical input/output time (approximately 40 ms/io) becomes a bottleneck, and no matter how fast the CPU alone is, it has the disadvantage that it is not very effective.
