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.

摘要翻译： 公开了一种包含单独地址空间的隔离原理的方法和/或计算机程序，并且通过基于语言的模型来实现与编译器的原理并支持运行时。 这种方法显着降低了所需的开销，并保留了可扩展的隔离模型的有益质量。 该模型以编程语言实现，其中基于存储器的状态被分割成多个域，其中域内的变量与外部组件隔离。 代理被引入域内部，并代表域外的客户端进行操作。 代理商通过消息传递与客户端进行通信，以强制实现域状态的隔离。 基于域的隔离解决了基于内存的状态的划分，而不引入单独的进程。 域也可以在单个计算设备内部或计算设备之间与分布式模型结合使用。

摘要： Multiple types of executable agents operating within a domain. The domain includes mutable shared state and immutable shared state, with agents internal to the domain only operating on the shared state. Writer agents are defined to be agents that have read access and write access to mutable shared state and read access only to immutable shared state. General reader agents have read access to both mutable shared state and immutable shared state and have no write access. Immutable reader agents have read access to only immutable shared state and have no write access. By appropriate scheduling of the different types of agents, data races may be reduced or eliminated.

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 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 H 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： The compilation of user code. Upon accessing the user code, the compiler determines that the user code includes at least one top-level asynchronous operation that is 1) to operate at a top-level of the stack of the programmed code, 2) that is programmed using a syntax for synchronous operations and 3) includes at least one indicator that the operation is to be asynchronous. The user code is then compiled such that the top-level asynchronous operation programmed in the syntax for synchronous operations is transformed into an asynchronous pattern suitable for the runtime environment.

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.
