LOW LATENCY COMPUTER SYSTEM POWER REDUCTION

摘要

Technology for handling overcurrent conditions on electrical circuits that power multiple computing modules is disclosed. Aspects of the technology include a power system adapted to provide notifications of overcurrent conditions, and computing modules adapted to reduce an operating speed thereof in response to notification of an overcurrent condition.

主权项

1. A method of managing power in a multi-server computing system, the method comprising:
detecting an occurrence of a current exceeding a threshold in a circuit that supplies power to multiple computing modules of the multi-server system; and in response to detecting the occurrence, reducing power consumption of at least two computing modules of the multiple computing modules, wherein reducing the power consumption for each of the at least two computing modules includes:
asserting a speed reduction pin of a processor of that computing module;while the speed reduction pin of the processor is asserted, writing a speed control register of the processor of that computing module; andreleasing the speed reduction pin of the processor of that computing module.
