TME (Task Mapping Editor): tool for executing distributed parallel computing. Design report on TME

At the Center for Promotion of Computational Science and Engineering, a software environment PPExe has been developed to support distributed parallel execution of scientific programs on a computer cluster. TME (Task Mapping Editor) is one of components of the PPExe and provides a visual programming environment. Users can easily specify data dependencies among tasks (programs) visually as a data flow diagram and map these tasks onto computers through GUI of TME. In this report, we summarize various functions of TME and describe the implementation methods of them. (author)
