Note
Performance and profiling tools are used on HPC sites for keeping codes execution times tamed.
This policy defines a set of performance and profiling tools and promotes their consistent maintenance (ie maintain compatible versions and configuration) across all systems of compatible sites. Same configuration is dependent on system compatibility, and also, some libraries may have slightly different configurations due to architectural differences. These differences, however, SHALL NOT affect the use of the libraries. A user moving from one resource to another is not expected to notice significant difference between the installations.

The suite of maintained packages consists of:
| Tool | Description | Compliance level | Reference |
|---|---|---|---|
| gprof | The GNU Profiler | MUST | http://www.gnu.org/software/binutils/ |
| PAPI | Consistent interface to hardware counters and events | MUST | http://icl.cs.utk.edu/papi |
| Valgrind | Memory management analysis and profiling | MUST | http://valgrind.org/ |
| Intel Vtune Analyzer | performance optimization tool NOTE: not open source but still relevant | SHOULD (commercial) | http://software.intel.com/en-us/articles/intel-vtune-amplifier-xe/ |
| UNITE | UNiform Integrated Tool Environment | SHOULD | http://apps.fz-juelich.de/unite |
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
- Support for PAPI and SCALASCA
- PDT: Source-level auto-instrumentation
http://www.cs.uoregon.edu/Research/tau PerfSuite software performance analysis http://perfsuite.ncsa.illinois.edu/ other hpctoolkit periscope marmot itac Extrae Paraver kcachegrind
The packages will be installed and maintained as part of a consistent computational environment.
