摘要： Optimizing workflow execution. A method includes identifying a completion condition. The completion condition is specified as part of the overall workflow. The method further includes identifying a number of activities that could be executed to satisfy the completion condition. One or more activities from the number of activities is ordered into an execution plan and assigned system resources based on an analysis of activities in the number of activities and the completion condition.

摘要： A method includes compiling an expression into executable code that is configured to create a data structure that represents the expression. The expression includes a plurality of sub-expressions. The code is executed to create the data structure. The data structure is evaluated using a plurality of concurrent threads, thereby processing the expression in a parallel manner.

摘要： A cancelation registry provides a cancelation interface whose implementation registers cancelable items such as synchronous operations, asynchronous operations, type instances, and transactions. Items may be implicitly or explicitly registered with the cancelation registry. A consistent cancelation interface unifies cancelation management for heterogeneous items, and allows cancelation of a group of items with a single invocation of a cancel-registered-items procedure.
摘要翻译：取消注册表提供了取消界面，其实现注册可同步操作，异步操作，类型实例和事务等可取消项。项目可以隐式或明确地注册到取消注册表。一致的取消界面统一了异构项目的取消管理，并允许通过单次调用cancel-registered-items过程来取消一组项目。

摘要： Dynamic data partitioning is disclosed for use with a multiple node processing system that consumes items from a data stream of any length and independent of whether the length is undeclared. Dynamic data partitioning takes items from the data stream when a thread is idle and assigns the taken items to an idle thread, and it varies the size of data chunks taken from the stream and assigned to a thread to efficiently distribute work loads among the nodes. In one example, data chunk sizes taken from the beginning of the data stream are relatively smaller than data chunk sizes taken towards the middle or end of the data stream. Dynamic data partitioning employs a growth function where chunks have a size related to single aligned cache lines and efficiently increases the size of the data chunks to occasionally double the amount of data assigned to concurrent threads.
摘要翻译：公开了与多节点处理系统一起使用的动态数据分区，其从任何长度的数据流消耗项目，并且与长度是否未声明无关。动态数据分区在线程空闲时从数据流中获取项目，并将所获取的项目分配给空闲线程，并且将从流中分配给分配给线程的数据块的大小变化，从而有效地在节点之间分配工作负载。在一个示例中，从数据流的开头获取的数据块大小相对于数据流的中间或结尾所采取的数据块大小相对较小。动态数据分区使用增长函数，其中块与单个对齐的高速缓存行相关联，并有效地增加数据块的大小，以偶尔将分配给并发线程的数据量加倍。

摘要： Transactional memory compatibility type attributes are associated with intermediate language code to specify, for example, that intermediate language code must be run within a transaction, or must not be run within a transaction, or may be run within a transaction. Attributes are automatically produced while generating intermediate language code from annotated source code. Default rules also generate attributes. Tools use attributes to statically or dynamically check for incompatibility between intermediate language code and a transactional memory implementation.

摘要： A parallelism policy object provides a control parallelism interface whose implementation evaluates parallelism conditions that are left unspecified in the interface. User-defined and other parallelism policy procedures can make recommendations to a worker program for transitioning between sequential program execution and parallel execution. Parallelizing assistance values obtained at runtime can be used in the parallelism conditions on which the recommendations are based. A consistent parallelization policy can be employed across a range of parallel constructs, and inside recursive procedures.

摘要： A data partitioning interface provides procedure headings to create data partitions for processing data elements in parallel, and for obtaining data elements to process, without specifying the organizational structure of a data partitioning. A data partitioning implementation associated with the data partitioning interface provides operations to implement the interface procedures, and may also provide dynamic partitioning to facilitate load balancing.
