Cloonix is a Linux router and host simulation platform. It fully encapsulates application, host, and network l2 and l3 into a relatively easy-to-use simulation GUI. Network delay and loss characteristics can be configured per link. It provides support for running kvm or UML virtual machines configured into an arbitrary complex network configuration. It is possible to run a 12 router UML simulation on a small x86 host (a P4 with 512 MB RAM). 32- and 64-bit KVM machines are provided.
Likwid is a set of easy to use command line tools for Linux. It supports programmers in developing high performance multi-threaded programs. "Likwid" stands for "Like I knew what I am doing". It contains the following tools: likwid-topology, which shows thread and cache topology; likwid-perfctr, which measures hardware performance counters on Intel and AMD processors; likwid-features, which shows and toggles hardware prefetch control bits on Intel Core 2 processors; likwid-pin, which pins a threaded application without touching its code (it supports pthreads, Intel OpenMP, and gcc OpenMP), likwid-powermeter which prints the Turbo mode steps and measures energy consumption on supported Intel processors, and likwid-bench, a low level benchmarking framework. It works with any standard Linux kernel. Likwid is lightweight and adds no overhead during measurements.
W-Meter is a tool for testing the conformance and evaluating the performance of 802.11 products. The tool is meant for injecting arbitrary frames to test the conformance of any wifi product. The tool has templates for generating various kinds of frames which can be customized for generation of specific frames. The tool can be used to elicit responses from other wifi cards to check the conformance of the card to the protocol. At present, 802.11g frames are completed.
MIN is an advanced unit/integration test framework for Maemo/Linux. It supports test cases written in C (or C++) as well as scripted test cases with (a tailor made) MIN scripter, Lua, or Python. Test cases are compiled into test modules that are loaded dynamically. A test case is executed in a separate process.
Scalasca is a toolset that can be used to analyze the performance behavior of parallel applications and to identify opportunities for optimization. It supports an incremental performance-analysis procedure that integrates runtime summaries with in-depth studies of concurrent behavior via event tracing, adopting a strategy of successively refined measurement configurations.
xCover is a code coverage library for C and C++. It uses non-standard features available with GCC 4.3+ and Visual C++ 7.0+. Users place line-marks in each branch of each function or method in a component's source file, and the library is able to produce, upon request, a report of which of these has not been executed. Reporting can be done on a per-file, per-alias, or per-file-group basis.
mutest is a micro unit testing framework for C (with some C++ support). It is easy to use and has no dependencies. The idea is simple: a source file is a test suite, and a function is a test case (special functions can be used for test suite initialization and termination) that can can have several checks. Checks comes in 2 flavors: one that only prints an error, and one that terminates the current test case too. A (normally) automated test program run all the test suites and prints some stats. It fails (returns non-zero) if any test suite fails.
IPv6 CARE, "IPv6 Compliant Automatic Runtime Environment", provides an environment where applications instantly become IPv6-compliant ('patch' mode, see RFC6535). It can also generate a diagnosis about the IPv6 compliance of an application ('check' mode). It uses an LD_PRELOAD-based library injection technique.
