BRL-CAD is a powerful constructive solid geometry solid modeling system that includes an interactive geometry editor, ray-tracing support for rendering and geometric analysis, path-tracing for realistic image synthesis, network distributed framebuffer support, and image and signal-processing tools.
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.
Hammerhead is a stress testing tool for Web sites. It initiates connections from multiple IP aliases and simulates a user from each alias. It is fully configurable, and there are numerous other options for creating problems with a site. Extensive data collection is also available.
This release is based on the Unix port of beta release 2 of BYTE Magazine's BYTEmark benchmark program (previously known as BYTE's Native Mode Benchmarks). The port to Linux/Unix was done by Uwe F. Mayer. Additional changes to the code were made to make the code work with egcs compiler and to make the software packagable. This is a CPU benchmark providing indexes for integer, floating, and memory performance. It is single-threaded and is not designed to measure the performance gain on multi-processor machines.
The Open Hardware Certification Program (OHCP) Test Suite is a collection of tests to verify the compatibility of your hardware with Open Source operating systems. Tests have been contributed by multiple authors and organizations, and are bundled with documentation, test procedures, and some automation scripts to help run the tests.
pingx is utility that uses the XNoOp(3x) call to see how fast your connection to your X server is. Wonder whether your X performance is slower in a SSH tunnel? pingx can give you hard numbers so you can find out. It has an option to print out some details about the X server as well. It's also useful to see if a destination X server is up so you can fire up x2x or similar applications intelligently.
Java Memory Profiler (JMP) uses the JVMPI interface to track objects and method times in the JVM (Java Virtual Machine). It uses a GTK+ interface to display statistics. The current instance count and the total amount of memory for each class is shown as is the total time spent in each method.
