The RDVIS tool helps programmers pin-point the sources of cache misses and poor temporal locality in their source code. The visualization often directs the experienced programmer towards the necessary program transformations within a few minutes. The tool consists of two parts: a GUI that visualizes the low temporal locality patterns, and a patched GCC compiler to extract the low-locality patterns from programs.
MPI Parallel Environment (MPE) is a software package for MPI (Message Passing Interface) programmers. It provides users with a number of useful tools for their MPI programs such as a set of profiling libraries that collect information about the behavior of MPI programs, graphical trace file analyzers, serializers, type checkers, collective operations validators, etc.
