摘要： Systems and methods facilitate efficient data processing in a computer environment. Data producers and consumers are considered in aggregate rather than in isolation. In one instance, interaction between data producers and consumers is improved by integrating producers and consumers. Optimization can subsequently be performed over the combination to produce synergistic results.

摘要： The present invention extends to methods, systems, and computer program products for marshaling results of nested tasks. Unwrap methods are used to reduce the level of task nesting and insure that appropriate results are marshaled between tasks. A proxy task is used to represent the aggregate asynchronous operation of a wrapping task and a wrapped task. The proxy task has a completion state that is at least indicative of the completion state of the aggregate asynchronous operation. The completion state of the aggregate asynchronous operation is determined and set from one or more of the completion state of the wrapping task and the wrapped task. The completion state of the proxy task can be conveyed to calling logic to indicate the completion state of the aggregate asynchronous operation to the calling logic.

摘要： An enumerable concurrent data structure referred to as a concurrent bag is provided. The concurrent bag is accessible by concurrent threads and includes a set of local lists configured as a linked list and a dictionary. The dictionary includes an entry for each local list that identifies the thread that created the local list and the location of the local list. Each local list includes a set of data elements configured as a linked list. A global lock on the concurrent bag and local locks on each local list allow operations that involve enumeration to be performed on the concurrent bag.

摘要： An object reference is tagged with an isolation permission modifier. At least two permissions can be included, and in an example three permissions are included. In implementing the permissions, type modifiers for controlling access to type members through references pointing at an object are defined. One of the type modifiers is associated with each occurrence of a type name. Each of the of type modifiers defines a different access permission to restrict operations on the object to which the reference points.

摘要： Partitioning query execution work of a sequence including a plurality of elements. A method includes a worker core requesting work from a work queue. In response, the worker core receives a task from the work queue. The task is a replicable sequence-processing task including two distinct steps: scheduling a copy of the task on the scheduler queue and processing a sequence. The worker core processes the task by: creating a replica of the task and placing the replica of the task on the work queue, and beginning processing the sequence. The acts are repeated for one or more additional worker cores, where receiving a task from the work queue is performed by receiving one or more replicas of tasks placed on the task queue by earlier performances of creating a replica of the task and placing the replica of the task on the work queue by a different worker core.

摘要： Embodiments described herein are directed to dynamically controlling the number of spins for a selected processing thread among a plurality of processing threads. A computer system tracks both the number of waiting processing threads and each thread's turn, wherein a selected thread's turn comprises the total number of waiting processing threads after the selected thread's arrival at the processor. Next, the computer system determines, based the selected thread's turn, the number of spins that are to occur before the selected thread checks for an available thread lock. The computer system also, based on the selected thread's turn, changes the number of spins, such that the number of spins for the selected thread is a function of the number of waiting processing threads and processors in the computer system.
摘要翻译：本文描述的实施例涉及动态地控制多个处理线程中所选择的处理线程的自旋数量。计算机系统跟踪等待处理线程和每个线程的轮次数，其中所选线程的回合包括所选线程到达处理器之后的等待处理线程的总数。接下来，计算机系统基于所选线程的轮次确定在所选线程检查可用线程锁之前将发生的自旋数。计算机系统还基于选择的线程轮到改变自旋数，使得所选线程的旋转数量是计算机系统中等待处理线程和处理器的数量的函数。

摘要： Fine-grained parallelism within isolated object graphs is used to provide safe concurrent operations within the isolated object graphs. One example provides an abstraction labeled IsolatedObjectGraph that encapsulates at least one object graph, but often two or more object graphs, rooted by an instance of a type member. By encapsulating the object graph, no references from outside of the object graph are allowed to objects inside of the object graph. Also, the encapsulated object graph does not contain references to objects outside of the graphs. The isolated object graphs provide for safe data parallel operations, including safe data parallel mutations such as for each loops. In an example, the ability to isolate the object graph is provided through type permissions.
