Program development support system and program development support software

A non-transitory computer readable medium containing program instructions for creating a program for performing data processing by a target device having a plurality of processing units, wherein execution of the program instructions by a computer which includes:

• a graphical user interface part;
• a graph information-holding part;
• a program-creating part;
• a process-executing function database;
• and
• a data-transfer function database, and
• which has a display device and an input device connected thereto,
• cause:
• displaying, by the graphical user interface part, graph information of the data processing executed by the target device on the display device as a graph, provided that in the graph, a plurality of processes included in the data processing make nodes respectively and flows of data form directed connection lines,
• holding, by the graph information-holding part, the graph information,
• holding, by the process-executing function database, process-executing functions for executing the processes by appropriate ones of the plurality of processing units, capable of executing the processes,
• holding, by the data-transfer function database, data-transfer functions functions for executing the process-executing functions by the corresponding processing units,
• reading, by the program-creating part, an appropriate process-executing function from the process-executing function database based on the graph information, reading an appropriate data-transfer function from the data-transfer function database, and creating the program,
• of the processes, executing a first process by any of first and second processing units of the plurality of processing units, provided that the first and second processing units are different from each other in kind,
• holding, by the process-executing function database, a first process-executing function for executing the first process by the first processing unit, and a second process-executing function for executing the first process by the second processing unit,
• holding, by the data-transfer function database, at least one of a first data-transfer function for executing the first process-executing function with the first processing unit, and a second data-transfer function for executing the second process-executing function with the second processing unit,
• on condition that the data processing includes the first process, displaying, by the graphical user interface part, the fact that the first or second processing unit can execute the first process at a node corresponding to the first process on the display device, and making possible to select, by the input device, which of the first and second processing units to use for executing the first process, and
• selectively reading, by the program-creating part, the first or second process-executing function from the process-executing function database, corresponding to the processing unit selected by the input device, selectively reading the first or second data-transfer function from the data-transfer function database, and creating the program.
