September, 1989

Today's supercomputers are mainly used to solve numerical problems.
Understanding the characteristics of numerical programs is therefore
essential for the design of supercomputers and their compilers. A run-time
information gathering tool has been developed that allows (1) the study of
program properties as they relate to vectorization and (2) the study of the
efficiency of vector transformation used in vectorizing compilers. This
paper describes the dynamic tool based on the PFC vectorizer and the
results gained from the analysis of a testsuite of eight computationally
intensive numerical programs.
