The method embodiment of the invention comprises receiving from a requestor a request for a reservation of resources in the cluster environment, reserving a first group of resources, evaluating resources within the cluster environment to determine if the response time can be improved and if the response time can be improved, then canceling the reservation for the first group of resources and reserving a second group of resources to process the request at the improved response time.

Abstract: A multi-tenant environment is described with a configurable hardware logic platform (e.g., a Field Programmable Gate Array (FPGA)) positioned on a host server computer. The configurable hardware logic platform can be programmed with a host logic wrapper portion, which is controlled by a service provider, and a customer portion, which is programmed with logic provided by a tenant of the service provider. While the host logic wrapper portion is reprogrammed, protections are put in place to prevent a virtual machine or the customer logic from violating security built within the host logic wrapper portion. Such protections can be suspending communications between the virtual machine and the customer logic until the host logic wrapper is reprogrammed.

Abstract: A method of determining a multi-agent schedule includes defining a well-formed, non-preemptive task set that includes a plurality of tasks, with each task having at least one subtask. Each subtask is associated with at least one resource required for performing that subtask. In accordance with the method, an allocation, which assigns each task in the task set to an agent, is received and a determination is made, based on the task set and the allocation, as to whether a subtask in the task set is schedulable at a specific time. A system for implementing the method is also provided.

Abstract: Migration configuration data for an organization migration to move application data and application services of a to-be-migrated organization hosted at a source system instance to a target system instance is received. Migration components respectively representing to-be-migrated systems of record in a to-be-migrated organization are registered. In response to receiving an instruction to enter a specific organization migration state, migration steps for each migration component in the migration components are identified for execution in the specific organization migration state. Each migration component in the migration components automatically executes migration steps determined for each such migration component for execution in the specific organization migration state.

Abstract: A method and system for optimizing the interaction and execution of multiple service tasks associated with a logical transaction. The multiple components or “legs” of the transaction consisting of tasks executable by a computing service or software as a service (SAAS) endpoint are identified. The system determines a strategy type or belief level associated with each of the service tasks included in a transaction. The belief level may be categorized as either “optimistic” or “pessimistic” based on one or more performance parameters (e.g., a probability of failure of a service and an expense associated with a failure of the service) derived from historical data associated with a particular transaction or service task. A sequence of execution for the multiple service tasks associated with the transaction is determined based at least in part on the belief level associated with each of the multiple service tasks.

In one embodiment, a user connection server is configured to receive a request for allocation of a virtual machine, for a user. The user connection server determines an attribute value of the user. Based on the attribute value of the user, allocation of physical computing resources for the virtual machine is determined. A management server is configured to boot the virtual machine for access by the user, the virtual machine booted with the determined allocation of physical computing resources for the virtual machine.

Abstract: Technologies for dynamic acceleration of general-purpose code include a computing device having a general-purpose processor core and one or more hardware accelerators. The computing device identifies an acceleration candidate in an application that is targeted to the processor core. The acceleration candidate may be a long-running computation of the application. The computing device translates the acceleration candidate into a translated executable targeted to the hardware accelerator. The computing device determines whether to offload execution of the acceleration candidate and, if so, executes the translated executable with the hardware accelerator. The computing device may translate the acceleration candidate into multiple translated executables, each targeted to a different hardware accelerator. The computing device may select among the translated executables in response to determining to offload execution.

Abstract: The subject matter of this specification can be implemented in, among other things, a method that includes receiving, from within a guest operating system hosted by a host operating system at a computer system, requests to access sparse files within a guest file system of the guest operating system. The sparse files each correspond to an external data file outside the guest file system.

The method includes identifying a frequency with which each of the sparse files is accessed. The method includes moving an external data file from a first type of storage device to a second type of storage device based on the frequency with which the external data file is accessed relative to others of the external data files.

Abstract: Various embodiments of methods and systems context-aware thermal management in a portable computing device (“PCD”) are disclosed. Notably, the environmental context to which a PCD is subjected may have significant impact on the PCD's thermal energy dissipation efficiency.

Abstract: A wait optimizer circuit can be coupled to a processor to monitor an entry of a virtual CPU (vCPU) into a wait mode to acquire a ticket lock. The wait optimizer can introduce an amount of delay, while the vCPU is in the wait mode, with an assumption that the spinlock may be resolved before sending a wake up signal to the processor for rescheduling. The wait optimizer can also record a time stamp only for a first entry of the vCPU from a plurality of entries into the wait mode within a window of time. The time stamps for vCPUs contending for the same ticket lock can be used by a hypervisor executing on the processor for rescheduling the vCPUs.

Abstract: In general, techniques are disclosed for tracking and allocating graphics processor hardware over specified periods of time. More particularly, hardware sensors may be used to determine the utilization of graphics processor hardware after each of a number of specified intervals (referred to as “sample intervals”). The utilization values so captured may be combined after a first number of sample intervals (the combined interval referred to as an “epoch interval”) and used to determine a normalized utilization of the graphic processor's hardware resources. Normalized epoch utilization values have been adjusted to account for resources used by concurrently executing processes. In some embodiments, a lower priority process that obtains and fails to release resources that should be allocated to one or more higher priority processes may be detected, paused, and its hardware resources given to the higher priority processes.
