Multi-processor system, conflict avoidance and methods conflict avoidance program

摘要

PPROBLEM TO BE SOLVED: To provide a multiprocessor system, a contention avoidance program and a contention avoidance method, allowing scheduling for avoiding resource contention to a process of using a resource after detecting the resource that is a factor of the resource contention. PSOLUTION: The multiprocessor system 100 includes: a contention detection part 12 for detecting the resource contention based on a request for a lock and/or a latency time after the request of the lock to the resource used by another process operating on another CPU when one process operating on one CPU of a plurality of CPUs uses the resource; an avoidance target specification part 13 for specifying the resource of a detected contention target as an avoidance target; and an execution CPU determination part 7 for determining whether or not each process is a process using the resource of the avoidance target when uprising of each process, and allocating the one CPU of the plurality of CPUs to each uprising process.
