【発明の名称】ホストコンピュータとテープ駆動部間の相互接続用のテープ駆動制御ユニットおよびその操作方法
Document Type and Number:
Japanese Patent JP2807010
Kind Code:
B2
Abstract:
A method and apparatus for loosely coupling a plurality of processors in a multiprocessor system to perform a coordinated task. The coordination of the task is implemented by an early start mode data transfer apparatus which coordinates the reading and writing of data files into and out of the data buffer (101) of the control unit (100) so that a data file can be written into the data buffer (101) while another file is concurrently being read out of the data buffer (101). Thus, both the host computer (130) and the associated tape drive units (140) can be active at the same time that data files are being read from or written into the data buffer (100) of the tape control unit (101).
