[More] symmetric multiprocessing high-performance ray-tracer, network-distributed framebuffer support, image and signal-processing tools, ray-tracing support for rendering and geometric analysis, path-tracing for realistic image synthesis, numerical processing libraries, a system performance analysis benchmark suite, an embedded scripting interface, and a robust high-performance geometric representation and analysis library. BRL-CAD is extensively cross-platform supporting Windows, Mac OS X, Linux, BSD, IRIX, Solaris, and more. BRL-CAD's development heritage of more than 20 years continues to grow. [Less]

Inquisitor is an open-source hardware testing and certification platform, suitable for both enterprise and home use, customizable, modular and available in both serverless Live CD/DVD format and server-controlled network boot production system.

Bootchart is a tool for performance analysis and visualization of the GNU/Linux boot process. Resource utilization and process information are collected during the boot process and are later rendered in a PNG, SVG or EPS encoded chart.

Ftop is to files what top is to processes. The progress of all open files and file systems can be monitored. If run as a regular user, the set of open files will be limited to those in that user's ... [More] processes (which is generally all that is of interest to the user). In any case, the selection of which files to display is possible through a wide assortment of options. As with top, the items are displayed in order from most to least active. The interface extends beyond the traditional capabilities and expectations of console applications. For instance, ftop supports two output modes, full (using ncurses) and limited (simple plain text). The output mode can be specified at invocation, or changed dynamically as the program runs. Limited output mode is well suited for piping into other utilities (such as grep or sed) or simply for redirecting into a file. Full output mode is much more visually appealing and contains a few more features. Keyboard control and interaction is not limited to full output mode; it is also available in limited output mode. As another unique usability feature, the command line options for ftop exactly match the run-time keyboard commands. In other words, the '-p' command line option can be used to specify a list of processes at invocation, and while ftop is running, 'p' can be pressed to modify the list. As another example, '-h' will show the help screen when ftop starts, or 'h' can be pressed at any time afterward to show the help screen. This commonality exists for every configuration option. And the current value for all options can be viewed at a glance in the options screen. Finally, ftop can also be easily configured to display additional files that are not currently open by any local processes, and file system usage. If an NFS client is writing a file on a local export, that file may not be open by any local process, so the additional files feature is used to display those files. One or more file systems can be monitored if many files are being created, for instance while restoring from a backup or extracting a large archive. Ftop has many more features than those described here. Detailed online help describes all available functionality, and provides examples of some of the interesting ways in which ftop can be used.

Sibefs - Simple Filesystem Benchmark Options: -d Directory to test, by default current directory is used -m RAM to use by sibefs. This is size of one block for read/write command -f Minimum ... [More] file size -F Maximum file size -r Number of test repeats -q Disk space to use -s Use fsync() after write each file. Benchmark scenario: 1. Create and write n=q/(size*2) files 2. Make a copy of n files 3. Read n files 4. Delete 2*n files (original and cop) 5. Calculate size=0.5*size 6. Go to step 1 Examples: sibefs -f 1k -F 10M -q 1G -m 1024 -s 0 sibefs -q 100m -s 1 No warranty. Use at your own risk ! [Less]

Research ways of making Linux scale better, both in terms of more processors and more processes.

Seat Graffiti is a small application that performs some simple benchmarks to test the CPU speed, RAM speed, and disk I/O speed (more benchmarks coming soon). Seat Graffiti 1-3 onwards is based on ... [More] the public domain Seat Graffiti 1-2 codebase, and is written by the original developer. Seat Graffiti 1-3 onwards is '''NOT''' public domain, and is instead licensed under the BSD License, in the interest of being able to link to any software you deem fit. [Less]
