In this research project, we first extract the intermediate representation from Parafrase-2 to develop a C++ version of our new parallelizing compiler called Narafrase. At the same time, we gave the definition of and designed the data partitioning graph as our universal intermediate representation. The optimization of communication overhead will be solved by our proposing cc-COMA technology. Then, we combined user interface library with the universal intermediate representation for Narafrase by collaborating with PROMIS parallelizing compiler developed by Prof. Polychronolous (investigator). We also implemented several parallelization methods on Narafrase with the use of the user interface library. Now we are implementing an algorithm for simultaneous partitioning of data and program for Narafrase. On the other hand, we have investigated and implemented a parallelization support tool by 3D visualization. The support tool, NaraView, collaborates with Narafrase so that users can parallelize their sequential programs effectively and easily. In this way, we have developed a prototype parallelizing compiler system for massively parallel computers.
