Abstract: A partition that is executed by multiple processing nodes. Each node includes multiple cores and each of the cores has a frequency that can be set. A first frequency range is provided to the cores. Each core, when executing the identified partition, sets its frequency within the first frequency range. Frequency metrics are gathered from the cores running the partition by the nodes. The gathered frequency metrics are received and analyzed by a hypervisor that determines a second frequency range to use for the partition, with the second frequency range being different from the first frequency range. The second frequency range is provided to the cores at the nodes executing the identified partition. When the cores execute the identified partition, they use a frequencies within the second frequency range.

Abstract: The efficiency rating (ER) of each domain, in a processor, may be compared and then the power budget may be allocated, effectively, among the domains based on the ERs of the domains. The ER may indicate relative advantage among domains in terms of performance return for a given power budget, i.e., a higher effectiveness may be expected in power utilization if the ER is higher for a domain. The ER of a domain may be defined as (scalability factor/cost factor*alpha). The scalability factor may be defined as a performance increase (in %) brought about by an increase in the clock frequency (in %) provided to the domain. The cost factor may be defined as a power budget value required in bringing about an increase in the clock frequency provided to the domain and alpha is an adjustment factor.

Abstract: A computer is made usable in a short time using a fingerprint authentication device. When a fingerprint authentication device performs authentication successfully, the fingerprint authentication device sends a startup signal to a power controller via a line.

In the fast boot, initialization of a USB interface of a line and password input by a user are skipped, and a BIOS accesses a system by single sign-on using a password stored in a secure area.

Abstract: A request for a high voltage mode is received and a high voltage timer is started in response to determining that a remaining amount of high voltage credits exceeds a voltage switch threshold value. A switch to the high voltage mode is made in response to the request. A low voltage mode is switched to in response to an indication. The request may be received from an application running on a data processing system. If the indication is that the high voltage timer has expired, a low voltage timer is started in response to switching to low voltage mode. If the high voltage request is still active when the low voltage timer expires, a switch back to high voltage mode occurs and a new high voltage timer is started.
