摘要:
A first power supply is configured to feed power to a computer. The power supply includes a virtual machine management unit configured to transmit an instruction to any one of a second virtual host that is executed on the computer and a fourth virtual machine that is run in the second virtual host. Here, the fourth virtual machine is configured to control a virtualization management system including virtual hosts different from the second virtual host.

摘要:
Technologies are generally described for systems, devices and methods effective to schedule access to a core. In some examples, a first differential voltage frequency scaling (DVFS) value of a first virtual machine may be received by a virtual machine manager. A second DVFS value of a second virtual machine may be received by the virtual machine manager. A third DVFS value of a third virtual machine may be received by the virtual machine manager. The third DVFS value may be substantially the same as the first DVFS value and different from the second DVFS value. A dispatch cycle may be generated to execute the first, second and third virtual machines on the core. After execution of the first virtual machine, the dispatch cycle may require execution of the third virtual machine before execution of the second virtual machine.

摘要:
Various embodiments of methods and systems for controlling and/or managing thermal energy generation on a portable computing device are disclosed. Data discarded from one or more processing core registers may be monitored and analyzed to deduce individual workloads that have been processed by each of the cores over a unit of time. From the deduced workloads, the power consumed by each of the cores over the unit of time in order to process the workload can be calculated. Subsequently, a time dependent power density map can be created which reflects a historical and near real time power consumption for each core. Advantageously, because power consumption can be correlated to thermal energy generation, the TDPD map can be leveraged to identify thermal aggressors for targeted, fine grained application of thermal mitigation techniques. In some embodiments, workloads may be reallocated from the identified thermal aggressors to the identified underutilized processing components.

摘要:
A method of operating a heterogeneous computer system for executing tasks of software that has at least one performance processor, a processor supporting logic, and a hypervisor processor. The method either i) boots up the hypervisor processor only; or ii) boots up the at least one performance processor after the hypervisor processor; or iii) boots up the at least one performance processor only; or iv) boots up the hypervisor processor after the at least one performance processor. The hypervisor processor executes tasks that the hypervisor processor has sufficient processing power to handle and puts the at least one performance processor to power-conserving state. The hypervisor processor brings the at least one performance processor out of power-conserving state to execute tasks that the hypervisor processor has insufficient processing power to handle. The at least one performance and hypervisor processors simultaneously execute tasks that require combined processing power of all processors.
