Lock-free data structures are process, thread and interrupt safe (i.e. the same data structure instance can be safely used across processes, threads and both inside and outside of interrupt handlers), never sleep (and so are safe for kernel use when sleeping is not permitted), operate without context switches, cannot fail (no need to handle error cases, as there are none), perform and scale literally orders of magnitude better than locking data structures, and liblfds itself (as of release 7.0.0) is implemented such that it performs no allocations and compiles not just on a freestanding C89 implementation, but on a bare C89 implementation.


  • A list of open source C++ libraries (cppreference.com)
  • Flux is a library of odds and ends related to data storage and indexing, marshalling, transfer, compression and encryption. It also features a slew of utility functions for various purposes. It is written in C, using the GLib paradigm.

Tools – Unit Tests

  • UnitTest++ is a lightweight unit testing framework for C++. It was designed to do test-driven development on a wide variety of platforms. Simplicity, portability, speed, and small footprint are all very important aspects of UnitTest++. UnitTest++ is free software. The license is the same as the MIT/X Consortium license. UnitTest++ is ANSI portable C++ and makes minimal use of advanced library and languages features, which means it should be easily portable to just about any platform. Out of the box, the following platforms are supported: Win32, Linux, Mac OS X.
  • Catch – a modern, C++-native, header-only, framework for unit-tests, TDD and BD.
  • CxxTest is a unit testing framework for C++ that is similar in spirit to JUnit, CppUnit, and xUnit. CxxTest is easy to use because it does not require precompiling a CxxTest testing library, it employs no advanced features of C++ (e.g. RTTI) and it supports a very flexible form of test discovery.

Tools – Profilers

  • Intel® VTune™ Performance Analyzer evaluates applications on all sizes of systems based on Intel® processors, from embedded systems through supercomputers, to help you improve application performance. VTune Performance Analyzer makes application performance tuning easier and is indispensable for making your software run its fastest on the latest single and multicore systems.
  • Valgrind is an award-winning instrumentation framework for building dynamic analysis tools. There are Valgrind tools that can automatically detect many memory management and threading bugs, and profile your programs in detail. You can also use Valgrind to build new tools. It runs on the following platforms: X86/Linux, AMD64/Linux, PPC32/Linux, PPC64/Linux, and X86/Darwin (Mac OS X).
  • OProfile is a system-wide profiler for Linux systems, capable of profiling all running code at low overhead. OProfile is released under the GNU GPL.
  • Coverity Prevent for C/C++ – optimize software integrity and decrease development time with the most precise static source code analysis solution available today. Coverity Prevent for C/C++ automatically identifies and helps resolve the most critical quality defects, security vulnerabilities and concurrency defects at the earliest stage in the software development cycle. It is the product of choice for developers who demand flexibility, maturity and accuracy in source code analysis. Prevent helps development teams ensure the integrity of the critical software code they deliver by automating the defect discovery process at the earliest stage of the production lifecycle.
  • Bullseye Coverage – quickly find untested C++ code and measure testing completeness.
  • OpenGrok is a fast and usable source code search and cross reference engine. It helps you search, cross-reference and navigate your source tree. It can understand various program file formats and version control histories like Mercurial, Git, SCCS, RCS, CVS, Subversion, Teamware, ClearCase, Perforce, Monotone and Bazaar. In other words it lets you grok (profoundly understand) the open source, hence the name OpenGrok. It is written in Java.
  • Klocwork – provides source code analysis tools that boost development productivity. Over 700 organizations use Klocwork‘s static analysis technology to identify security vulnerabilities and quality defects, optimize their peer code review process, and enable developers to create more maintainable code.
  • Likwid is a simple to install and use toolsuite of command line applications for performance oriented programmers. It works for Intel and AMD processors on the Linux operating system.
  • Test programs for measuring clock cycles and performance monitoring -test programs that I have used for my research. Can measure clock cycles and performance monitor counters such as cache misses, branch mispredictions, resource stalls etc. in a small piece of code in C, C++ or assembly. Can also set up performance monitor counters for reading inside another program. Supports Windows and Linux, 32 and 64 bit mode, multiple threads.
  • Micro benchmarking libraries for C++ .
  • CppBenchmark – C++ Benchmark Library allows to create performance benchmarks of some code to investigate average/minimal/maximal execution time, items processing processing speed, I/O throughput. CppBenchmark library has lots of features and allows to make benchmarks for different kind of scenarios such as micro-benchmarks, benchmarks with fixtures and parameters, threads benchmarks, produsers/consummers pattern.

Tools – Code review

  • List of tools for static code analysis
  • Artistic Style – A Free, Fast and Small Automatic Formatter for C, C++, C#, and Java Source Code
  • Vera++ – Programmable verification and analysis tool for C++
  • Splint is a tool for statically checking C programs for security vulnerabilities and coding mistakes. With minimal effort, Splint can be used as a better lint. If additional effort is invested adding annotations to programs, Splint can perform stronger checking than can be done by any standard lint.

Tools – Code analysing

  • Cppcheck – is an static analysis tool for C/C++ code. Unlike C/C++ compilers and many other analysis tools it does not detect syntax errors in the code. Cppcheck primarily detects the types of bugs that the compilers normally do not detect. The goal is to detect only real errors in the code (i.e. have zero false positives).
  • Visual Lint is Riverblade’s solution for developers who require advanced static code analysis capabilities within the Microsoft Visual Studio and eMbedded Visual C++ integrated development environments.


  • LLDB is a next generation, high-performance debugger. It is built as a set of reusable components which highly leverage existing libraries in the larger LLVM Project, such as the Clang expression parser and LLVM disassembler. LLDB is the default debugger in Xcode on Mac OS X and supports debugging C, Objective-C and C++ on the desktop and iOS devices and simulator.
  • VMKit: a substrate for virtual machines. The VMKit project is a framework for building virtual machines. It uses LLVM for compiling and optimizing high-level languages to machine code, and MMTk to manage memory. J3 is an implementation of a JVM with VMKit. You can get and build the source of J3 today.
  • The KLEE Symbolic Virtual Machine. KLEE is a symbolic virtual machine built on top of the LLVM compiler infrastructure, and available under the UIUC open source license.
  • C-Free is a professional C/C++ integrated development environment (IDE) that support multi-compilers. Use of this software, user can edit, build, run and debug programs freely.
  • Code::Blocks is a free C++ IDE built to meet the most demanding needs of its users.
  • VisualDDK – develop/debug drivers directly from VS
  • Eclipse
