  • 32 OpenMP Traps For C++ Developers

    20.11.2009
    Since multi-core systems are spreading fast, the problem of parallel programming becomes more and more urgent. However, even the majority of experienced developers are new to this sphere. The existing compilers and code analyzers allow finding some bugs, which appear during parallel code development. However, many errors are not diagnosed. The article contains description of a number of errors, which lead to incorrect behavior of parallel programs created with OpenMP. Read more

    At present, Viva64 and VivaMP software products are included in PVS-Studio as parts of it and are no longer distributed as separate applications. Please use PVS-Studio program to obtain the necessary possibilities of code verification.. Read more

  • Using Static Analysis in Program Development

    31.01.2008
    Static analysis allows checking program code before the tested program is executed. The static analysis process consists of three steps. First, the analyzed program code is split into tokens, i.e. constants, identifiers, reserved symbols, etc. This operation is performed by lexer. Second, the tokens are passed to parser, which builds an abstract syntax tree (AST) based on the tokens. Finally, the static analysis is performed over the AST. This article describes three static analysis techniques: AST walker analysis, data flow analysis and path-sensitive data flow analysis. Read more
