The goal of UNITE is to provide a robust, portable, and integrated environment for the debugging and performance analysis of parallel MPI, OpenMP, and hybrid MPI/OpenMP programs on high-performance compute clusters. It consists of a set of well-accepted portable, mostly open-source tools. UNITE itself includes:
|mpiP | Lightweight, Scalable MPI Profiling | http://mpip.sourceforge.net/ |
|SCALASCA | Scalable trace analysis package | http://www.scalasca.org/ |
|Vampir | Performance Optimization | http://www.vampir.eu/ |
|TAU | Performance analysis of parallel applications \\ * PDT: Source-level auto-instrumentation \\ * Support for PAPI and SCALASCA | http://www.cs.uoregon.edu/Research/tau |
|SCALASCA | Scalable trace analysis package |
|Vampir | Performance Optimization |

The packages will be installed and maintained as part of a consistent computational environment.
