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.

Dynamic voltage control

A link based system including a plurality of processors is reset when transitioning from a slower speed to a higher speed mode during a booting process. One processor may coordinate the simultaneous establishment of link resetting of a plurality of other processors. In one embodiment, the processors may operate beginning with the farthest processor to reset their local links. Each processor sets its local links and if it determines, based on the speed of the link that the link has already been reset, it moves on to the next link.
