摘要： A method of statically testing dependence in a dataflow program is provided, the method comprising receiving a dataflow program which provides parameters, including specified consumption rates and specified production rates on connections between actors in the program and a specified number of initial samples (delays) on at least a part of the connections, generating from the parameters a model of a precedence graph for the dataflow program representing dependence constraints between distinct firings of the number of actors, analysing the model of the precedence graph by selecting a minimum/maximum index vertex from a set of successor/predecessor vertices, such that the minimum/maximum index vertex depends on a given predecessor/successor vertex while considering only the dependence constraints on the edge between the predecessor/successor and the set of successor/predecessor vertices, and determining for each selected minimum/maximum index vertex if the selected minimum/maximum index vertex is dependent on itself or if a termination requirement is fulfilled to thereby establish whether a cyclic dependence is present.

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.
