C++ Benchmarking Library
This project is now maintained at GitHub: https://github.com/DigitalInBlue/Celero Celero is a cross-platform open source C++ benchmarking library. Written with an API similar to Google Test, Celero utilizes C++11 features, offers tested benchmarking capabilities with microsecond precision, baselining, fixtures, and easy test setup. Use the baseline feature to measure/benchmark algorithm performance against a known case to more accurately rate performance of solutions.
In order to assure software performance, software needs to be tested accordingly as early as possible - only weaknesses diagnosed early can be assessed quickly and cheaply. ContiPerf enables performance testing already in early development phases and in an easy-to-learn manner: A developer writes a performance test in form of a JUnit 4 test case and adds performance test execution settings as well as performance requirements in form of Java annotations. When JUnit is invoked by an IDE, build script or build server, ContiPerf activates, performs the tests and creates an HTML report. The report provides a detailed overview of execution, requirements and measurements, even providing a latency distribution chart. A large feature set for execution settings and performance requirements is available, e.g. Ramp up, warm up, individual pause timing, concurrent exection of test groups and more.
Java and C Comparative Performance Benchmarks
A collection of software benchmarks developed to compare the performance of Java with C on identical code. No language libraries were used to avoid implementation differences. Some of the benchmarks are also implemented in Python and Scala. There are benchmarks for bit twiddling, numerical computing, data structure manipulation, concurrent computing, callouts to native libraries, and, graphics processing units (GPU) utilization.
SarBox helps user to parse or analyze sar data
SarBox helps user to parse or analyze sar data. SarBox helps to show graphical data along with values. The sar command writes to standard output the contents of selected cumulative activity counters in the operating system, usually Unix.
A free Fortran 2008, 2015 coarrays course with notes and exercises
Coarrays are a feature of standard Fortran since 2008 standard. The 2015 standard adds a lot of functionality, e.g. collectives, teams, events. Coarrays are used extensively in the CGPACK library (http://cgpack.sf.net) and other projects. The course is aimed at experienced Fortran users. Working knowledge of Fortran is assumed. The course is designed for a 1 day study with an instructor. Multiple exercises with full solutions are accompanied by notes in PDF or HTML. We teach this course to staff and students at the University of Bristol, UK, as part of the set of HPC courses offered to HPC users at Bristol. Exercises have been verified with Intel and GCC/OpenCoarrays. All course materials are released under BSD license. We welcome contributions, provided you are happy to release your work under BSD license. We also welcome comments and problem reports. Contact CMPLX Engineering (http://cmplx.uk) if you want us to deliver this course to your organisation.
Note: this tool has moved to github, this repository is not maintained any more. See https://github.com/turdusmerula/ftrace GScopeLog is a tool for instrumenting c++ code through gcc. The main purpose is to trace entry/exit point of functions. A status file may be generated to give overview of functions calls and timing informations with minimal impact on performances.
lsperf is an utility listing performance of various computer components.
Reads a PostgreSQL database log file, extracts the SQL statements and executes them in the same order and timing against another database server. Useful for performance tests with real-world workload.
Benchmarking and stress testing tool for the Zabbix agent
A multithreaded Zabbix agent benchmarking tool with support for custom keys and discovery item prototypes. This tool is useful for developing custom Zabbix agent items and quickly identifying memory or file handle leaks, concurrency problems such as race conditions and other performance issues.
