Abstract:
1. A computer-implemented method of managing a parallel computing system that comprises a plurality of compute nodes, comprising: monitoring a first parameter of a first one of the plurality of compute nodes, wherein the first parameter comprises at least one of: a measured temperature, a measured current, and a measured power consumption, and wherein the plurality of compute nodes in the parallel computing system are coupled for data communications; upon determining that the first parameter reaches or exceeds a first threshold for the first parameter, transmitting a global interrupt to at least two of the plurality of compute nodes that are configured to reduce power consumption upon receiving the global interrupt, wherein the at least two compute nodes comprises the first one of the plurality of compute nodes, and wherein the at least two compute nodes form an operational group that is a subset of the plurality of compute nodes; after transmitting the global interrupt, determining whether second parameters of each of the at least two compute nodes in the operational group reach or fall below a second threshold for the second parameters, wherein the second parameters comprise at least one of: a measured temperature, a measured current, and a measured power consumption; and only after all the second parameters are at or below the second threshold, cancelling the global interrupt for the at least two compute nodes in the operational group.
