CALCULATION RESOURCE ALLOCATION DEVICE, CALCULATION RESOURCE ALLOCATION METHOD, AND CALCULATION RESOURCE ALLOCATION PROGRAM

摘要

A multi-core processor system wherein each of a plurality of processors is provided with a cache memory.  An allocation management unit manages task allocation to respective processors.  A cache status calculation unit calculates a cash usage status such as a memory access number, a cache hit rate, etc., per task.  A first processor processes a plurality of first tasks belonging to a first process.  When a calculation amount of the first process exceeds a predetermined threshold value, the allocation management unit refers to the cache usage status, and selects a moving target task, from the plurality of first tasks, so that a task having a smaller memory access number or having a higher cache hit rate, has a higher selection priority.  The allocation management unit newly allocates the moving target task to a second processor which processes a process different from the process processed by the first processor.
