Parallel Programming With Hierarchically Tiled Arrays

153 p.Thesis (Ph.D.)--University of Illinois at Urbana-Champaign, 2007.To prove these claims, two popular languages, C++ and MATLAB, have been extended with HTA. In addition, the NAS benchmark suite, a set of complex computation intensive parallel programs, have been re-written using HTAs. We compare the lines of code and execution times of HTA programs with that of FORTRAN versions. Our results show that the codes written using HTAs are very readable and at the same efficient. We also show several sample code snippets to demonstrate the clarity of the HTA programs. All the experiments indicate that the explicit notion of tiles makes HTA a powerful language construct for writing a wide range of high performance programs.U of I OnlyRestricted to the U of I community idenfinitely during batch ingest of legacy ETD
