Abstract
In an approach for controlling voltage, a computer obtains a magnitude of a current of a processing unit. The computer determines an optimized magnitude of a voltage based on the obtained magnitude of the current. The computer generates an updating instruction based on the determined optimized magnitude of the voltage. The computer supplies the generated updating instruction to the processing unit.
Claims6
A method for controlling voltage, the method comprising:
- obtaining, by one or more computer processors, a magnitude of a current of a processing unit, wherein the current is dynamic;
- determining, by one or more computer processors, whether the magnitude of the current of the processing unit changes in real time, wherein the magnitude of the current changes based on a change to a workload parameter;
- responsive to determining the magnitude of the current of the processing unit changes, identifying, by one or more computer processors, a range that is a set of output values that includes the obtained magnitude of the current;
- dividing, by one or more computer processors, the range into at least a first portion and a second portion;
- determining, by one or more computer processors, a function for each of the first portion and the second portion, wherein the function for each of the first portion and the second portion are non-linear;
- determining, by one or more computer processors, an optimized magnitude of a voltage based on the obtained magnitude of the current and the determined function for each of the first portion and the second portion;
- generating, by one or more computer processors, an updating instruction based on the determined optimized magnitude of the voltage;
- and
- supplying, by one or more computer processors, the generated updating instruction to the processing unit.
