| Outline of Final Research Achievements |
Double precision operations in the HPC are the major computing mode for the numerical computations in the science and engineering. This research focus on the higher precision computing more than double precision operations, i.e. quadruple precision operations. One of final targets of this research is free distribution of such software obtained through the research. Under three years of research period, new computer language specification with features of (1) easy description of more than quadruple precision operations, (2) good for high performance computing, is fixed. (3) Now is the stage of creating translator of such new computer language. However the translator is insufficient for the real usage in the functionality and performance point of views.
