Abstract:
1. A method of optimizing power consumption of a parallel computing system of the type that includes a plurality of computing nodes configured to process a workload, the method comprising: respectively executing a plurality of parts of the workload on the plurality of computing nodes in the parallel computing system, including concurrently executing a first part of the workload on a first computing node among the plurality of computing nodes and a second part of the workload on a second computing node among the plurality of computing nodes; and selectively throttling performance of the first computing node during execution of the first part of the workload to decrease power consumption of the first computing node and to conform a completion time for the first computing node in completing the first part of the workload with a completion time for the second computing node in completing the second part of the workload, wherein selectively throttling performance of the first computing node further comprises:
