    Abstract: Information representative of a graph-based program specification has a plurality of components, each of which corresponds to a task, and directed links between ports of said components. A program corresponding to said graph-based program specification is executed. A first component includes a first data port, a first control port, and a second control port. Said first data port is configured to receive data to be processed by a first task corresponding to said first component, or configured to provide data that was processed by said first task corresponding to said first component. Executing a program corresponding to said graph-based program specification includes: receiving said first control information at said first control port, in response to receiving said first control information, determining whether or not to invoke said first task, and after receiving said first control information, providing said second control information from said second control port.

    Abstract: A first component of a graph-based program specification includes an output control port. A second component includes an input control port and an input data port. A third component includes an output data port. The output control port is connected to the input control port, and the output data port is connected to the input data port. The first component includes control code that when executed causes the output control port to provide, to the input control port, at least one of suppression information or invocation information. The second component includes control code that when executed causes a computing system configured by the graph-based program specification to begin processing data received at the input data port in response to the invocation information if no suppression information is received at the input control port before the invocation information is received at the input control port.

    Abstract translation: 基于图表的程序规范的第一个组件包括一个输出控制端口。 第二组件包括输入控制端口和输入数据端口。 第三个组件包括一个输出数据端口。 输出控制端口连接到输入控制端口,输出数据端口连接到输入数据端口。 第一组件包括控制代码,当执行时,输出控制端口向输入控制端口提供抑制信息或调用信息中的至少一个。 第二组件包括控制代码,当被执行时,使得由基于图表的程序规范配置的计算系统在响应于调用信息开始处理在输入数据端口处接收的数据,如果在输入控制端口之前没有接收到抑制信息 在输入控制端口接收到调用信息。
