摘要： Unsuspended co-routines are handled by the machine call stack mechanism in which the stack grows and shrinks as recursive calls are made and returned from. When a co-routine is suspended, however, additional call stack processing is performed. A suspension message is issued, and the entire resume-able part of the call stack is removed, and is copied to the heap. A frame that returns control to a driver method (a resumer) is copied to the call stack so that resumption of the co-routine does not recursively reactivate the whole call stack. Instead the resumer reactivates only the topmost or most current frame called the leaf frame. When a co-routine is suspended, it does not return to its caller, but instead returns to the resumer that has reactivated it.

摘要： APIs are provided, that are external to a programming language but that provide functionality that can be plugged into a language compiler. The provided APIs tailor functionality associated with asynchronous programming, iterators or writing symmetric co-routines using a generalized pattern-based approach. Several types of resumable methods are provided in the APIs which can be applied to method bodies written in traditional program code. Syntactically distinguishable control points in method bodies written in traditional program code invoke transformation of the code by the compiler using the external APIs. The transformed code enables the pausing and resumption of the code sandwiched between control points in the transformed code. The source code contained within a method having control points in it is transformed so that code within the method can be executed in discrete parts, each part starting and ending at a control point in the transformed code.

摘要： The present invention extends to methods, systems, and computer program products for transforming source code to await execution of asynchronous operations. Embodiments of the invention simplify authoring and use of asynchronous methods, by generating statements that use well-defined awaitable objects to await completion of asynchronous operations. For example, a computer system can transform a statement that requests to await the completion of an asynchronous operation into a plurality of statements that use a predefined pattern of members of an awaitable object corresponding the asynchronous operation. The pattern can include one or more members configured to return a completion status of the asynchronous operation, one or more members configured to resume execution of the asynchronous method at a resumption point when the asynchronous operation completes, and one or more members configured to retrieve completion results. Accordingly, the plurality of statements can use these members to await execution of the asynchronous operation.

摘要： A scheduler in a process of a computer system includes a respective scheduling collection for each scheduling node in the scheduler. The scheduling collections are mapped into at least a partial search order based on one or more execution metrics. When a processing resource in a scheduling node becomes available, the processing resource first attempts to locate a task to execute in a scheduling collection corresponding to the scheduling node before searching other scheduling collections in an order specified by the search order.

摘要： The scheduling of dataflow components in a dataflow network. A number, if not all, of the dataflow components are created using a domain/agent model. A scheduler identifies, for a number of the components, a creation source for the given component. The scheduler also identifies an appropriate domain-level access permission (and potentially also an appropriate agent-level access permission) for the given component based on the creation source of the given component. Tokens may be used at the domain or agent level to control access.

摘要： A compiler that enforces, at compile time, domain data access permissions and/or agent data access permissions on at least one agent to be created within a domain. The compiler identifies domain data of a domain to be created, and an agent to be created within the domain at runtime. The domain access permissions of the agent are also identified. As part of compilation of an expression of an agent, a reference to the domain data is identified. Then, the compiler evaluates an operation that the reference to the domain data would impose on the domain data upon evaluating the expression at runtime. The compiler then determines whether or not the operation is in violation of the domain access permissions of the agent with respect to the identified domain data. Agent data access may also be evaluated depending on whether the access occurs by a function or a method.

摘要： A method and/or computer program that incorporates isolation principles of separate address spaces and enforces the principles with a compiler and supporting runtime through a language-based model is disclosed. This approach significantly lowers the required overhead and retains the beneficial qualities of the scalable, isolated model. The model is implemented in a programming language where memory-based state is partitioned into a plurality of domains where the variables inside of a domain are isolated from external components. Agents are introduced inside of the domain and act on behalf of clients outside of the domain. The agents communicate with their clients via message-passing to enforce the isolation of the domain state. The domain-based isolation addresses the partitioning of memory-based state without the introduction of separate processes. Domains can also be used in conjunction with a distributed model either within a single computing device or between computing devices.
