Abstract: Systems and methods provide a processing task load and type adaptive manycore processor architecture, enabling flexible and efficient information processing. The architecture enables executing time variable sets of information processing tasks of differing types on their assigned processing cores of matching types. This involves: for successive core allocation periods (CAPs), selecting specific processing tasks for execution on the cores of the manycore processor for a next CAP based at least in part on core capacity demand expressions associated with the processing tasks hosted on the processor, assigning the selected tasks for execution at cores of the processor for the next CAP so as to maximize the number of processor cores whose assigned tasks for the present and next CAP are associated with same core type, and reconfiguring the cores so that a type of each core in said array matches a type of its assigned task on the next CAP.

Abstract: One embodiment sets forth a method for assigning priorities to kernels launched by a software application and executed within a stream of work on a parallel processing subsystem. First, the software application assigns a desired priority to a stream using a call included in the API. The API receives this call and passes it to a driver. The driver maps the desired priority to an appropriate device priority associated with the parallel processing subsystem. Subsequently, if the software application launches a particular kernel within the stream, then the driver assigns the device priority associated with the stream to the kernel before adding the kernel to the stream for execution on the parallel processing subsystem. Advantageously, by assigning priorities to streams and, subsequently, strategically launching kernels within the prioritized streams, an application developer may fine-tune the software application to increase the overall processing efficiency of the software application.

Abstract: A task is marked as dependent upon a preceding task. The task that is attempted to be taken for execution from a head of a pending task queue that is marked is deferred. The deferred task is removed from the pending task queue and placed in a deferred task queue. The deferred task is reinserted back into the pending task queue for execution upon determining that the preceding tasks are completed.

Abstract: Approaches for executing untrusted software on a client without compromising the client using micro-virtualization to execute untrusted software in isolated contexts. In response to receiving a request to perform an action, an isolated environment (such as but not limited to a virtual machine) is instantiated without receiving an explicit user instruction to do so. To instantiate the isolated environment, one or more templates for use in instantiating the isolated environment are identified using a policy. The one or more templates describe isolated environment characteristics for different types of activity. After the isolated environment has been instantiated using one or more identified templates, the action may be performed in the isolated environment.

Abstract: There is provided with a resource allocation apparatus. An attribute indicating a requirement for a data storage resource to be allocated to a plurality of data flows to which the attribute is provided beforehand is acquired. A data flow relationship graph indicating a relationship between the plurality of data flows which potentially lead to access contention in the data storage resource is generated. Based on the attribute and the data flow relationship graph, allocation of the data storage resource to the plurality of data flows is determined such that no access contention occurs.

Abstract: Selective resource migration is disclosed. A computer system includes physical memory and a plurality of physical processors. Each of the processors has one or more cores and each core instantiates one or more virtual processors that executes program code. Each core is configured to invoke a hyper-kernel on its hosting physical processor when the core cannot access a portion of the physical memory needed by the core. The hyper-kernel selectively moves the needed memory closer to a location accessible by the physical processor or remaps the virtual processor to another core.

Abstract: Aspects of the present invention are directed at providing safe and efficient ways for a program to perform a one-time initialization of a data item in a multi-threaded environment. In accordance with one embodiment, a method is provided that allows a program to perform a synchronized initialization of a data item that may be accessed by multiple threads. More specifically, the method includes receiving a request to initialize the data item from a current thread. In response to receiving the request, the method determines whether the current thread is the first thread to attempt to initialize the data item. If the current thread is the first thread to attempt to initialize the data item, the method enforces mutual exclusion and blocks other attempts to initialize the data item made by concurrent threads. Then, the current thread is allowed to execute program code provided by the program to initialize the data item.

Abstract: Various aspects of the disclosure relate to monitoring of resource usage in a virtualized environment, including usage of a physical processor that executes a virtual machine or an application of the virtualized environment. By monitoring physical computing resources (e.g., by number and type) that are used to execute a virtual machine or an application of the virtualized environment, a user may, for example, be informed as to when physical computing resources are used in excess or less than the limits set by the license. In some embodiments, additional actions may be taken to update the license to better satisfy the user's resource requirements or reduce the amount paid annually for ongoing technical services. To inform a user, or form the basis for the additional actions, a report may be generated that includes data describing how a virtual machine or application executed on the physical computing resources.

Abstract: Mechanisms for distributing workload items to a plurality of dispatchers are provided. Each dispatcher is associated with a different computing system of a plurality of computing systems and workload items comprise workload items of a plurality of different workload types. A capacity value for each combination of workload type and computing system is obtained. For each combination of workload type and computing system, a queue length of a dispatcher associated with the corresponding computing system is obtained. For each combination of workload type and computing system, a dispatcher's relative share of incoming workloads is computed used on the queue length for the dispatcher associated with the computing system. In addition, incoming workload items are routed to a dispatcher, in the plurality of dispatchers, based on the calculated dispatcher's relative share for the dispatcher.

Abstract: A system, method, and computer program product are provided for identifying, quantifying, and reducing wasted resources in software testing. In use, a first duration of time over which at least one software testing environment was not available for at least one first software testing project is determined.
