摘要： A high level programming language provides a map transformation that takes a data parallel algorithm and a set of one or more input indexable types as arguments. The map transformation applies the data parallel algorithm to the set of input indexable types to generate an output indexable type, and returns the output indexable type. The map transformation may be used to fuse one or more data parallel algorithms with another data parallel algorithm.

摘要： A scheduler in a process of a computer system detects a task with an associated execution context that has not been previously invoked by the scheduler. The scheduler executes the task on a processing resource without performing a context switch if the processing resource executed a previous task to completion. The scheduler stores the execution context originally associated with the task for later use.

摘要： A scheduler in a process of a computer system schedules tasks of a task group for concurrent execution by multiple execution contexts. The scheduler provides a mechanism that allows the task group to be cancelled by an arbitrary execution context or an asynchronous error state. When a task group is cancelled, the scheduler sets a cancel indicator in each execution context that is executing tasks corresponding to the cancelled task group and performs a cancellation process on each of the execution contexts where a cancel indicator is set. The scheduler also creates local aliases to allow task groups to be used without synchronization by execution contexts that are not directly bound to the task groups.
摘要翻译：计算机系统进程中的调度器调度任务组的任务，用于多个执行上下文的并发执行。调度程序提供了允许任务组被任意执行上下文或异步错误状态取消的机制。当任务组被取消时，调度器在执行对应于被取消的任务组的任务的执行上下文中设置取消指示符，并且对设置了取消指示符的每个执行上下文执行取消处理。调度程序还创建本地别名，以允许不直接绑定到任务组的执行上下文同时使用任务组。

摘要： A XLANG/s compilation method is provided that uses data flow analysis of a program's flow graph to determine lifetimes of a data object. A flowgraph is created according to abstract computer instructions. A depth-first order is assigned to basic blocks and a dominance relationship between the basic blocks is determined. A determination is made as to whether any loops are present within the flowgraph and, if so, the loops are identified. A creation point, destruction point and lock point for the data object is determined. Instructions are inserted into the computer code to create the at least one data object at the creation point, to destroy the data object at the destruction point and to lock the data object at the lock point.

摘要： A high level programming language provides extensible data parallel semantics. User code specifies hardware and software resources for executing data parallel code using a compute device object and a resource view object. The user code uses the objects and semantic metadata to allow execution by new and/or updated types of compute nodes and new and/or updated types of runtime libraries. The extensible data parallel semantics allow the user code to be executed by the new and/or updated types of compute nodes and runtime libraries.

摘要： An XLANG/s compiler detects convoy scenarios during compilation and generates runtime directives to correctly correlate incoming messages with business process instances. A convoy scenario, present in event driven processes, is defined by a correlation set initialized during a receive operation which is provided to a subsequent receive operation. The compiler detects those convoy scenarios by analyzing the control and dataflow of a XLANG/s program. Three convoy patterns are distinguished: (1) activation convoys, (2) uniform sequential convoys, and (3) non-uniform sequential convoys. XLANG/s allows declarative descriptions of convoy scenarios without requiring an understanding of the low-level details supporting their correct execution. Convoy scenarios are processed by statically analyzing a written workflow application to deduce the nature and type of convoy scenarios used by the application. Information is extracted at compile time to support the runtime infrastructure. The runtime infrastructure is tightly integrated with the underlying correlation and subscription evaluation framework.

摘要： Creating and executing a distributed stream processing operator graph based on a query. The operator graph includes movable stream algebra operators for processing events received from high volume data streams. The operators are partially compiled and distributed to computing devices for completion of the compilation and subsequent execution. During execution, the operators maintain minimal state information associated with received events via an expiration time assigned to each of the event instances. Additional events are generated and aggregated by the operators for communication to a service responsible for the query.
