Bootchart is a tool for performance analysis and visualization of the GNU/Linux boot process. Resource utilization data and process information are collected during the boot process, and can later be displayed in a PNG, SVG, or EPS encoded chart. Analyzing the chart will help in finding opportunities for optimization.
Cactus is a general, modular, parallel environment for solving systems of partial differential equations. The code has been developed over many years by a large international collaboration of numerical relativity and computational science research groups and can be used to provide a portable platform for solving any system of partial differential equations.
The Contest program is designed to test system responsiveness by running Linux kernel compilation under a number of different load conditions. It is designed to compare different kernels, not different machines. It uses real workloads you would expect to find for short periods of time in everyday machines, but sustains them for the duration of a kernel compile to increase the signal to noise ratio.
DJFractal is yet another fractal generator which distributes fractal data to multiple computers. Fractal data are created locally and distributed to other computers that run the appropriate fractal-generation software, which may be hosted on workstations, or on a Java enabled Web-browser through applets, or on a system with JavaCard. DJFractal's unique feature is the "smart" algorithm it uses to compute (and draw) the most interesting part of a fractal first.
FSHeal aims to be a general filesystem tool that can scan and report vital "defective" information about the filesystem like broken symlinks, forgotten backup files, and left-over object files, but also source files, documentation files, user documents, and so on. It will scan the filesystem without modifying anything and reporting all the data to a logfile specified by the user which can then be reviewed and actions taken accordingly.
FunkLoad is a functional and load Web tester whose main use cases are functional testing of Web projects (and thus regression testing as well), performance testing, load testing (such as volume testing or longevity testing), and stress testing. It can also be used to write Web agents to script any Web repetitive task.
