Versionsverwaltung zur Unterstuetzung der Analyse und Optimierung von SVM-Fortran Programmen

By using the shared memory programming model it is possible to parallelize applications step by step (in contrast to the message passing programming model) because there is no need for an initial data distribution. SVM-Fortran is a programming language for shared vitual memory architectures. Due to the high abstraction level of SVM-Fortran, a sophisticated performance analysis tool is needed. OPAL (Optimizer and Locality Analyzer) is a source code based performance analysis tool developed for this purpose. It supports selective instrumentation to reduce the impact of measuring on runtime. The incremental program development and the selective tracing approach leads to a large number of program versions and trace files which are difficult to handle. To evaluate the efficiency of an optimization step, a convenient access to all program versions and traces is a must. Thus a version management facility has been integrated into OPAL which leads the user to document his work by adding comments to the program versions and traces. The comment consists of a single line abstract and a structured, detailed part. The single line abstracts are used to help selecting a program version or a trace file, whereas the purpose of the structured, detailed part is documentation. Further features have been integrated into OPAL to support the complete development cycle consisting of analyzing, editing, compiling and executing SVM-Fortran programs under a single graphical interface.
