Performance Analysis Environment for SVM-Fortran Programs

This report outlines the design of a performance analysis environment for SVM-Fortran programs. SVM-Fortran is a shared memory parallel programming language developed at KFA for distributed memory multiprocessors. The environment allows to analyze the data locality of a given program via runtime tracing and supports the identification of critical code regions to guide the user or an optimization tool in tuning the program. To reduce the amount of runtime data, the environment combines trace data with static program information and supports an incremental analysis cycle. In addition to the overall design, we present the trace format of runtime events. The trace format includes symbolic information to relate runtime information to the program text which is the essential part of the user interface. The performance analysis environment is part of OPAL, a tool that will combine performance analysis and program optimization
