High Speed I/O Processing for Shared Memory Multiprocessor Systems

공유 메모리 다중 프로세서 시스템에서 고속 입출력 처리 기법

This paper suggests the new high-speed input/output techniques in a shared memory multiprocessor system. The high-speed I/O processor which can connect the different kinds of large sized I/O periperal devices, the communication protocol to the main processing units for I/O operations, and the job scheduling scheme are addressed. This paper also introduces the disk cache technique which supports the slow I/O devices comparing with the main processing units. These techniques were implemented in the TICOM system. The performance evaluation statistics were collected and analyzed for the suggested high-speed I/O processing techniques. These statistics show the superiority of the suggested techniques.
