Method and Apparatus for Managing Nodal Power in a High Performance Computer System

摘要

A method controls power consumption in a high performance computing system having a plurality of nodes by gathering information relating to the plurality of nodes in the high performance computing system, setting a power range to a given power range for the plurality of nodes as a function of the gathered information, and executing an application program on one or more of the nodes. The method also receives power commands from the application program relative to the one or more nodes, and responsively changes the power range to a new power range for the one or more nodes executing the application program. Thus, the one or more nodes execute the application program within the new power range.

1. A method of controlling power consumption in a high performance computing system having a plurality of nodes, the plurality of nodes having a given power range, one or more of the plurality of nodes executing an application program, the method comprising:
receiving power commands from the application program relative to the one or more nodes executing the application program; and changing the power range, in response to the power commands, from the given power range to a new power range for the one or more nodes for executing the application program, the one or more nodes executing the application program within the new power range.
