Factors Affecting the Performance of Tiled Numerical Codes

Abstract

The topic I am investigating is High Performance Computing. I am investigating the factors affecting the outcome of speed of tiled dense array programs. The significance and applications of parallel computing are countless. As the field expands, different approaches are taken to optimize performance in HPC. It is paramount to not only investigate methods for continued innovation in the field, but to look at the methods already out there and how a combination of these methods can provide promising results. The ISCC software transformation tool was used with different tile arrangements to investigate which factors affected the speed at which programs could be run sequentially or in a parallel. In addition to this, the tile arrangements and distribution with different tile sizes were tested. The results obtained were significant and showed that using the certain combinations of tile shape and iteration performed a significant amount better than other tile arrangements.
