High performance with high accuracy laboratory

Abstract

ln order to obtain high performance with high accuracy in the so lution of scientific computational problems, a computational tool has been developed, called High Performance with High Accuracy Labora tory. ln this paper we describe initially the high performance and then the high accuracy and the interval mathematics. After that , the tool is described, including two environments in which it has been developed, that is, the Cray Supercomputer vector environment and the paral lel environment based on Transputers. The description summarizes the modules, the basic interval library, the high accuracy arithmetic kernel, the interval applied modules, especially the selint.p library. Finally, there are some comments about the performance
