Abstract: A method allocates energy entitlement to a logical partition (LPAR) executing on a data processing system. An energy entitlement allocation (EEA) utility enables an administrator to specify a minimum and/or maximum energy entitlement and an LPAR priority. When the relevant LPARs utilize the respective minimum energy entitlement based on a respective energy consumption, the EEA utility determines whether the LPAR(s) has satisfied a respective maximum energy entitlement. When the LPAR has not satisfied its maximum energy entitlement, the EEA utility allocates unused energy entitlement from the data processing system to the LPAR, according to an allocation policy. Additionally, the EEA utility dynamically adjusts a priority level for the LPAR to efficiently control resource allocation, according to the LPAR's energy consumption relative to its energy entitlement.

Abstract: A system and computer program product allocates energy entitlement to a logical partition (LPAR) executing on a data processing system. An energy entitlement allocation (EEA) utility enables an administrator to specify a minimum and/or maximum energy entitlement and An LPAR priority. When the relevant LPARs utilize the respective minimum energy entitlement based on respective energy consumption, the EEA utility determines whether the LPAR (and other LPARs) has satisfied a respective maximum energy entitlement. When the LPAR has not satisfied its maximum energy entitlement, the EEA utility allocates unused energy entitlement from the data processing system to the LPAR, according to an allocation policy. Additionally, the EEA utility dynamically adjusts a priority level for the LPAR to efficiently control resource allocation, according to the LPAR's energy consumption relative to its energy entitlement.

Abstract: A technique is provided for administering references to a subject process filesystem during translation of subject code into target code in a dynamic binary translator. The subject code for execution on a subject processor is received by a translator, and corresponding target code for execution on the target processor is generated. The translator is arranged to establish, populate and maintain a process data structure, so that code can be generated by the translator in which subject references to the subject process filesystem are handled effectively.
