摘要： A dataflow program defining actors that pass tokens from one to another via connections is processed by causing one or more processors to access and execute instructions of the dataflow program. Execution of the dataflow program generates events (e.g., token production/consumption, actor state after actor action firing). For each generated event, processing evaluates whether there exists a sequence of events that matches a breakpoint condition, and if such a sequence exists then execution of the dataflow program is halted. The breakpoint condition is at least partially based on an extended history of related events, wherein two events are related to one another if they pertain to a same connection or if they pertain to a same actor state, and wherein the extended history comprises at least two related events.

摘要： Processing a dataflow program by a program development tool includes detecting a pair of actors defined by dataflow program instructions, wherein the pair of actors include a producer actor and a consumer actor, the producer actor supplying a data structure to the consumer actor via a path that comprises at least one connection and possibly also intervening other actors. An analysis is performed including analyzing one or more operations of the producer actor that involve the data structure and/or analyzing one or more operations of the consumer actor that involve the data structure. A result of the analysis is used as a basis for selecting a minimal amount of information from among a plurality of data handling possibilities concerning the data structure. A transformed program is produced in which the selected minimal amount of information is caused to be passed from the producer actor to the consumer actor.

摘要： A remote execution agent, having low-latency access to the platform, receives from a remote application, across a communication channel imposing a round-trip delay, a plurality of invocation control directives. The remote execution agent invokes operations for execution on the platform in response to the invocation control directives, and aggregates results from the operations, returning the aggregated results to the application. In this manner, overhead such as communication round-trip delay, context switching, and the like, is reduced, compared to the application sending separate operation invocation requests to the platform and receiving the results of each. The remote execution agent manages operation results, such as passing results from a prior operation as parameters for a later one. In some embodiments, the invocation control directives include conditional operation invocation and branching.
摘要翻译：具有对平台的低延迟访问的远程执行代理器通过施加往返延迟的通信信道，多个调用控制指令从远程应用接收。响应于调用控制指令，远程执行代理调用在平台上执行的操作，并聚合操作的结果，将聚合结果返回到应用程序。与向平台发送单独的操作调用请求并接收每个结果的应用相比，以这种方式减少诸如通信往返延迟，上下文切换等之类的开销。远程执行代理管理操作结果，例如将先前操作的结果作为后续参数的参数传递。在一些实施例中，调用控制指令包括条件操作调用和分支。

摘要： A software component deployed in a distributed system includes a stub that enables the component to be used remotely. The stub can include its own proxy (or at least a sufficient description of it) that is automatically and dynamically injected to the remote environment. Thus, native proxies do not need to be included in the platform initially, and do not need to be downloaded, since marshalling methods are generated at runtime based on a blueprint in the code of the application.
摘要翻译：部署在分布式系统中的软件组件包括一个可以远程使用组件的存根。存根可以包含自身和动态注入到远程环境的自己的代理（或至少有足够的描述）。因此，原始代理不需要最初被包括在平台中，并且不需要被下载，因为编组方法是基于应用程序的代码中的蓝图在运行时生成的。

摘要： A dataflow program defining actors that pass tokens from one to another via connections is processed by causing one or more processors to access and execute instructions of the dataflow program. As instructions of the dataflow program are being executed, a first set of trace records is created that represents a sequence of events (e.g., token production/consumption, actor state change, or action firing). A first subset of the trace records is displayed and one of these is selected. The first set is processed to identify, based on definitions specified by the dataflow program, a second set of trace records, of which a subset is displayed.
