摘要： Provided are a method and apparatus for task scheduling based on hardware. The method for task scheduling in a scheduler accelerator based on hardware includes: managing task related information based on tasks in a system; updating the task related information in response to a request from a CPU; selecting a candidate task to be run next after a currently running task for each CPU on the basis of the updated task related information; and providing the selected candidate task to each CPU. The scheduler accelerator supports the method for task scheduling based on hardware.

摘要： Techniques for temporarily and/or partially offloading mobile applications to one or more remote virtual machines in a server include establishing an application copy of a mobile application installed on a mobile device at a remote virtual machine, suspending the mobile application on the mobile device and offloading operations of the mobile application to the application copy at the remote virtual machine for a period of time. Suspending the mobile application and offloading its operations to the remote virtual machine for the period of time reduces consumption of resources on the mobile device. The virtual machine executes the application copy in the same manner the mobile device would execute the mobile application and transfers data from the execution to the mobile application at the end of the period of time to allow the mobile application to update itself and resume its operation without any loss of data or functionality.

摘要： Dynamic power routing is utilized to route power from other components, which are transitioned to lower power consuming states, in order to accommodate more efficient processing of computational tasks by hardware accelerators, thereby staying within electrical power thresholds that would otherwise not have accommodated simultaneous full-power operation of the other components and such hardware accelerators. Once a portion of a workflow is being processed by hardware accelerators, the workflow, or the hardware accelerators, can be self-throttling to stay within power thresholds, or they can be throttled by independent coordinators, including device-centric and system-wide coordinators. Additionally, predictive mechanisms can be utilized to obtain available power in advance, by proactively transitioning other components to reduced power consuming states, or reactive mechanisms can be utilized to only transition components to reduced power consuming states when a specific need for increased hardware accelerator power is identified.

摘要： Various embodiments are directed to a distributed computing task processor comprising a central computing entity and one or more mobile computing entities. The central computing entity is configured to generate task records corresponding to one or more tasks and to delegate various tasks to the one or more mobile computing entities. The mobile computing entities, in turn, are configured to complete the assigned tasks by retrieving data from various locations within a physical environment and/or by generating data locally on the mobile computing entity to be included in the task record to complete the task. The mobile computing entities may be configured to transmit the updated task records to the central computing entity for storage.

摘要： A method for the selective utilization of graphics processing unit (GPU) acceleration of database queries in database management is provided. The method includes receiving a database query in a database management system executing in memory of a host computing system. The method also includes estimating a time to complete processing of one or more operations of the database query using GPU accelerated computing in a GPU and also a time to complete processing of the operations using central processor unit (CPU) sequential computing of a CPU. Finally, the method includes routing the operations for processing using GPU accelerated computing if the estimated time to complete processing of the operations using GPU accelerated computing is less than an estimated time to complete processing of the operations using CPU sequential computing, but otherwise routing the operations for processing using CPU sequential computing.

摘要： A method and an apparatus that partition a total number of threads to concurrently execute executable codes compiled from a single source for target processing units in response to an API (Application Programming Interface) request from an application running in a host processing unit are described. The total number of threads is based on a multi-dimensional value for a global thread number specified in the API. The target processing units include GPUs (Graphics Processing Unit) and CPUs (Central Processing Unit). Thread group sizes for the target processing units are determined to partition the total number of threads according to either a dimension for a data parallel task associated with the executable codes or a dimension for a multi-dimensional value for a local thread group number. The executable codes are loaded to be executed in thread groups with the determined thread group sizes concurrently in the target processing units.

摘要： Techniques are disclosed relating to data transformation for distributing workloads between processors or cores within a processor. In various embodiments, a first processing element receives a set of bytecode. The set of bytecode specifies a set of tasks and a first data structure that specifies data to be operated on during performance of the set of tasks. The first data structure is stored non-contiguously in memory of the computer system. In response to determining to offload the set of tasks to a second processing element of the computer system, the first processing element generates a second data structure that specifies the data. The second data structure is stored contiguously in memory of the computer system. The first processing element provides the second data structure to the second processing element for performance of the set of tasks.
