MULTICORE PROCESSOR SYSTEM, SCHEDULING METHOD AND SCHEDULER PROGRAM

摘要

PPROBLEM TO BE SOLVED: To reduce the number of cores to be allocated as much as possible while satisfying request performance. PSOLUTION: A multicore processor system includes: a multicore processor 1; a plurality of software means 21, 22, 211, 221 each of which executes predetermined processing by using one of a plurality of cores included in the multicore processor 1; and a scheduler 23 for operating the plurality of software means in parallel by adjusting core allocation and core occupation time included in the multicore processor 1 with respect to the respective software means. Each of the software means outputs execution result data of predetermined processing to output buffers 213, 223 and issues a notification based on the accumulation amount of the execution result data outputted to the output buffers by the software means itself to the schedular. The schedular 23 increases and decreases the number of cores to be allocated and/or the core occupation time to each software means based on the received notification. PCOPYRIGHT: (C)2010,JPO&INPIT
