Abstract: An estimated time to migrate a VM from a source hypervisor to a target hypervisor is calculated. The estimated time is compared to a threshold time and based on the estimated time meeting the threshold time, a migration of the VM from the source hypervisor to the target hypervisor via the network is initiated. Based on the estimated time not meeting the threshold time, it is determined whether an additional path can be added to the network between the source hypervisor and the target hypervisor. If an additional path cannot be added to the network, a migration of the VM from the source hypervisor to the target hypervisor via the network is initiated. If an additional path can be added to the network, the additional path is added and the migration via the network is initiated.

Abstract: Application code is obtained at a compiler toolchain, which accesses a package manager that tracks dependencies for a set of software components including application-level components represented as application-level packages, hypervisor interface-level components represented as hypervisor interface-level packages, and hypervisor-level components represented as hypervisor-level packages. A dependency solver is employed to select a sub-set of the set of packages that satisfy the dependencies.

Abstract: A method and system for scheduling, for periodic execution, a program requiring a computer hardware resource for execution. A computer determines and records historic utilization or availability of the resource multiple times a day. The computer subsequently receives a request to schedule the program for execution on the day at a specified time and (a) daily, (b) weekly, or (c) monthly at the specified time, and in response, the computer determines if there has been historical availability of the resource exceeding a predetermined availability threshold on the day at approximately the specified time to execute the program, and if so, schedule the program for execution on the day at the specified time and (i) daily, (ii) weekly, or (iii) monthly thereafter, as requested, and if not, not schedule the program for execution on the day at the specified time or (i) daily, (ii) weekly, or (iii) monthly thereafter, as requested.

Abstract: The method includes post copy migrating a guest virtual machine from a migration source host to a migration target host, executing the instruction stream of the guest virtual machine on the migration target host, and determining, by the migration target host, when the guest virtual machine encounters the page fault. When the guest virtual machine encounters the page fault, the method includes requesting, by the migration target host, the not-present page from the migration source host for loading on the migration target host, and emulating, on an emulator executing on or in communication with the migration target host, continued execution of the instruction stream of the guest virtual machine. The method also includes identifying, by the emulator, future page references to future pages from the emulated continued execution of the instruction stream, and requesting the future pages from the migration source host in parallel with the not-present page request.

Abstract: Resource provisioning to a process in a distributed computing system, such as a cloud computing system. An instruction to provision a resource is received. Portions of the resource are provisioned to the process as they become available, and prior to all portions becoming available, based on determining that the provisioning speed is greater than or equal to the use speed for the resource. If the use speed is faster, it may be actively slowed down.

The shared pool of configurable computing resources has a set of virtual machines. A set of usage data for the user is established. The set of usage data corresponds to usage of an asset by the user. Based on the set of usage data for the user, an asset action for the asset for the user on a virtual machine is determined. In response to determining the asset action for the asset, the asset action for the asset for the user on the virtual machine is selected.

Abstract: Methods and apparatuses to reduce the number of read/write operations performed by a CPU may involve duplicating source data to enable parallel processing on the source data. A memory controller may be configured to duplicate data written to a first buffer to one or more duplicate buffers that are allocated to one or more processing threads, respectively. In some implementations, the one or more duplicate buffers are dedicated buffers, and the addresses of the first buffer and the one or more duplicate buffers are stored in a register of memory controller.

Abstract: An execution-flow-creation aiding apparatus obtains a written operation procedure that represents an operation procedure of a series of tasks involved in operation work. The execution-flow-creation aiding apparatus refers to component information and based on a result of comparing the task name of a task included among the series of tasks involved in operation work and the component name of a component, associates the task and the component. The execution-flow-creation aiding apparatus selects among the series of tasks, a second task that is not associated with a component and that is immediately before or after a first task associated with a given component. The execution-flow-creation aiding apparatus refers to the component information and based on a result of comparing the task name of the selected second task and the variable name of a variable provided when the given component is executed, associates the second task with the given component.

The cloud marketplace system can be configured to determine the resource and service data for the cloud computing environments and select a set of resource servers for instantiating the virtual machines based specifications of the virtual machines and parameters of the instantiation. The cloud marketplace system can be configured to periodically monitor the cloud's resources and migrate the virtual machines if resources become available that more closely match the parameters of the virtual machines.

Abstract: Various embodiments of methods and systems for energy efficiency aware thermal management in a portable computing device that contains a heterogeneous, multi-processor system on a chip (“SoC”) are disclosed. Because individual processing components in a heterogeneous, multi-processor SoC may exhibit different processing efficiencies at a given temperature, energy efficiency aware thermal management techniques that compare performance data of the individual processing components at their measured operating temperatures can be leveraged to optimize quality of service (“QoS”) by adjusting the power supplies to, reallocating workloads away from, or transitioning the power mode of, the least energy efficient processing components. In these ways, embodiments of the solution optimize the average amount of power consumed across the SoC to process a MIPS of workload.

Abstract: Described herein is an apparatus and method for remote scoped synchronization, which is a new semantic that allows a work-item to order memory accesses with a scope instance outside of its scope hierarchy. More precisely, remote synchronization expands visibility at a particular scope to all scope-instances encompassed by that scope. Remote scoped synchronization operation allows smaller scopes to be used more frequently and defers added cost to only when larger scoped synchronization is required. This enables programmers to optimize the scope that memory operations are performed at for important communication patterns like work stealing. Executing memory operations at the optimum scope reduces both execution time and energy. In particular, remote synchronization allows a work-item to communicate with a scope that it otherwise would not be able to access. Specifically, work-items can pull valid data from and push updates to scopes that do not (hierarchically) contain them.
