General purpose, language independentEdit
The following tools work based on log files that can be generated from various systems.
- time (Unix) - can be used to determine the run time of a program, separately counting user time vs. system time, and CPU time vs. clock time.
- timem (Unix) - can be used to determine the wall-clock time, CPU time, and CPU utilization similar to time (Unix) but supports numerous extensions.
- Supports reporting peak resident set size, major and minor page faults, priority and voluntary context switches via getrusage.
- Supports sampling procfs on supporting systems to report metrics such as page-based resident set size, virtual memory size, read-bytes, and write-bytes, etc.
- Supports collecting hardware counters when built with PAPI support.
The following tools work for multiple languages or binaries.
