Power-performance based system management

A computer management system comprising:

• a storage device;
• and
• a processor communicatively coupled to the storage device, wherein the processor is configured to:
• receive a workload for a computer system;
• iteratively adjust a plurality of parameters of the computer system while the workload is executed;
• monitor one or more characteristics of the computer system while adjusting the plurality of parameters, the one or more characteristics including total power consumption and performance measurement of the computer system;
• generate a power profile for the workload that specifies a single value for each parameter of the plurality of parameters, the single value for each parameter selected to maximize performance per power usage based on analysis of the monitored total power consumption and performance measurement of the computer system while sweeping the plurality of parameters;
• store the power profile on the storage device;
• and
• execute the workload concurrently with one or more other workloads based on the specified value of each parameter of the plurality of parameters in the power profile being within a predefined threshold of corresponding specified values of parameters in power profiles of the one or more other workloads.

A computer management system comprising:

• a power-performance management engine configured to:
• sweep a plurality of parameters of a computer system while a workload is executed;
• monitor one or more characteristics of the computer system while sweeping the plurality of parameters, the one or more characteristics including total power consumption and performance measurement of the computer system;
• and
• generate a power profile for the workload that specifies a single value for each parameter of the plurality of parameters, the single value for each parameter selected to maximize performance per power usage based on analysis of the monitored total power consumption and performance measurement of the computer system;
• and
• a power-performance workload scheduler configured to schedule the workload for execution concurrently with one or more other workloads based on the specified value of each parameter of the plurality of parameters in the generated power profile being within a predefined threshold of corresponding specified values of parameters in power profiles of the one or more other workloads.

A method comprising:

• comparing, by a power-performance management engine (PPME), respective power performance tables for each of a plurality of workloads, each power performance table specifying a single value for at least one parameter of a plurality of parameters of a computer system for executing the respective workload, and wherein the specified values of the plurality of parameters are selected to maximize performance per power usage based on monitoring one or more characteristics of the computer system, including power consumption and performance measurement of the computer system, while iteratively adjusting the plurality of parameters;
• identifying, by the PPME, at least two compatible workloads based on determining respective specified values for the plurality of parameters in the respective power performance tables are within a predefined threshold from the comparison of the respective power performance tables;
• scheduling, by a power-performance workload scheduler, the at least two compatible workloads to be executed concurrently by the a second computer system;
• and
• concurrently executing the at least two compatible workloads on the second computer system based on the respective specified values for the plurality of parameters in the respective power performance tables being within a predefined threshold from the comparison of the respective power performance tables.
