摘要：
A method and apparatus for use in a computing environment to run a variety of applications in logical partitions. The apparatus includes one or more logical processors (LPs), one or more logical partitions (LPARs) configured to each access a share of processing resources of the LPs in accordance with predefined instructions, and an LPAR manager configured to determine an operational mode of each of the LPARs and any available amount of an excess of the share of the processing resources of the LPs and to dispatch the processing resources of at least a subset of the LPs to the LPARs in accordance with the respective predetermined shares and with respect to the determined operational mode of the respective LPARs and the amount, if any, of the excess share.
