Collective Operation Management In A Parallel Computer

摘要

Methods, apparatuses, and computer program products for collective operation management in a parallel computer are provided. Embodiments include a parallel computer having a plurality of compute nodes coupled for data communications over a data communications network. Embodiments include a first compute node entering a collective operation. Each compute node of the plurality of compute nodes is associated with the collective operation. In response to entering the collective operation, the first compute node decreases power consumption of the first compute node.

1. A method of collective operation management in a parallel computer, the parallel computer including a plurality of compute nodes coupled for data communications over a data communications network, the method comprising:
entering, by a first compute node of the plurality of compute nodes, a collective operation, wherein each compute node of the plurality of compute nodes is associated with the collective operation; and decreasing, in response to entering the collective operation, by the first compute node, power consumption of the first compute node.
