Abstract: In a method, in response to an interface a computer-implemented analysis assistant initiates a presentation of inefficiency results, determined an efficiency analyzer based on a mapping of a dataflow program to execute on hardware of a computing system. The assistant receives an inefficiency included among the inefficiency results and composes formatted inefficiency results comprising a presentation format of the inefficiency to assist a developer of the dataflow program to interpret the inefficiency. The analysis assistant outputs the formatted inefficiency results to an interface, which can comprise an interface to output the formatted inefficiency results for use by the developer to improve the dataflow program in association with the inefficiency. In implementations the presentation can comprise an interactive presentation with a developer of the dataflow program. A computer program product and a computing system can implement the method.

Abstract: In a method a computer-implemented efficiency analyzer selects operators from an intermediate representation of a dataflow program. The operators are included in a mapping of the operators to hardware of a computing system to execute the dataflow program. Based on the mapping and a description of the hardware, the efficiency analyzer computes an execution metric associated with executing the operators on the hardware. Based on the execution metric and hardware description, the efficiency analyzer determines an inefficiency metric, and based on the inefficiency metric, the efficiency analyzer determines an inefficiency associated with the dataflow program. The computing system to execute the dataflow program can comprise a coarse grain computing system and the hardware can include a reconfigurable processor of the computing system. A computer program product and a computing system to a the dataflow program can implement the method.

Abstract: In a method a compiler performs a trial compilation to a low level (LL) intermediate representation (IR) of a high level (HL) decision to execute a dataflow application on a computing system. The LLIR comprises hardware resources to execute the application based on the HL decision and the compiler determines a trial result based on LL execution metrics associated with the trail compilation. The compiler performs a trial compilation of a second HL decision to a second LLIR and determines a trial result based on LL execution metrics associated with the second trail compilation. The compiler evaluates the trial results and, based on the evaluations, selects one or both of the HL decisions for executing the dataflow application. A computer program product and a computing system can implement the method.
