Method and system for automatically measuring partition memory needs in a partitioned computer system

摘要

A system and method for automatically reallocating resources among partitions based on factors including relative resource pain rates and user assigned priority. A tuner executes several tasks, including determining relative memory pain rates for partitions and allocating memory among partitions so that future relative memory pain rates obtained after the allocation will be more evenly distributed among the partitions than current relative memory pain rates are distributed. Also, the tuner determines current relative processor and interactive pain rates for partitions and allocates processor and interactive power among these partitions so that future relative processor and interactive pain rates obtained after the allocation will be more evenly distributed among the partitions than current relative processor and interactive pain rates are distributed. Also, the tuner creates a table showing, for a given system configuration, processor and interactive power amounts that may be validly allocated in combination to a partition.
