Abstract
Device Interface. The layered architecture has allowed research organizations and commercial vendors to port MPICH to a great variety of multiprocessor and multicomputer platforms and distributed environments. CHAPTER 1. INTRODUCTION 14 1.4 SCALA P 3 T+ calculates at compile time a set of performance parameters which reflect the quality of the chosen parallelization strategy based on the following data obtained by a single profile run of SCALA [31], a post-execution performance analysis tool developed at the Institute of Software Technology and Parallel Systems in Vienna: ffl Statement execution counts (how many times has a statement been executed during runtime of the program?) ffl Loop iteration counts (what is the average number of iterations of a specific loop throughout the execution of the program?) ffl Branching probabilities for conditional statements (how many times was a specific condition evaluated to TRUE throughout the execution of the program?) In following we des...
