摘要： The present invention extends to methods, systems, and computer program products for propagating unhandled exceptions in distributed execution environments, such as clusters. A job (e.g., a query) can include a series of computation steps that are executed on multiple compute nodes each processing parts of a distributed data set. Unhandled exceptions can be caught while computations are running on data partitions of different compute nodes. Unhandled exception objects can be stored in a serialized format in a compute node's local storage (or an alternate central location) along with auxiliary details such as the data partition being processed at the time. Stored serialized exception objects for a job can be harvested and aggregated in a single container object. The single container object can be passed back to the client.

摘要： A parallel execution runtime allows tasks to be executed concurrently in a runtime environment. The parallel execution runtime delegates the implementation of task queuing, dispatch, and thread management to one or more plug-in schedulers in a runtime environment of a computer system. The plug-in schedulers may be provided by user code or other suitable sources and include interfaces that operate in conjunction with the runtime. The runtime tracks the schedulers and maintains control of all aspects of the execution of tasks from user code including task initialization, task status, task waiting, task cancellation, task continuations, and task exception handling.

摘要： A method of performing a wait operation includes creating a first plurality of tasks and a continuation task. The continuation task represents a second plurality of tasks. The continuation task and each of the tasks in the first plurality have an associated wait handle. The wait handles for the first plurality of tasks and the continuation task are stored in an array. A wait operation is performed on the array, thereby waiting for at least one of the tasks in the first and second pluralities to complete.

摘要： A data/video server having the following elements: n I/O access channel connectors, m storage arrays and a commutator which connects individual ones of the I/O access channel connectors to different individual ones of the storage arrays in accordance with a connection diagram with which the server is being operated in accordance with at a given time, further includes a system (operating in accordance with a method) for enabling it to implement operation in accordance with a new connection diagram (which can enable the bandwidth provided to one or more I/O access channels coupled thereto to be changed). That system includes a bandwidth manager for generating a new connection diagram; and a control system, coupled to the bandwidth manager, for obtaining the new connection diagram and causing the elements of the server to implement operation in accordance with the new connection diagram. The bandwidth manager is included in one of the storage arrays, and the control system is made of microprocessors which are individually included in each of the different elements of the server. First counters are included in each of the elements to aid in synchronizing those elements so that they can implement operation in accordance the new connection diagram at substantially the same time. Second counters are included in the elements to aid the microprocessors ensuring that as the elements implement operation in accordance with the new connection diagram, by begin operating in accordance therewith, the beginning of such operating is subject to and in accordance with one or more transition rules. The server also includes a counter signal generator for incrementing the first and second counters when appropriate.

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.
