Programs are rarely built from a single source code file. Normally, code is organized into several source files, reaching hundreds or even thousands of files for large programs. Static code analysis tools work by analyzing the source code files. When a function defined in a source file calls another function defined in a different source […]

Using CMake’s compilation database with Parallelware Analyzer
When building a program, seldom do we only invoke the compiler passing a source file and an output binary name. In most cases, we must supply several compiler flags such as include paths or macro definitions. A program is usually built by compiling different source files where each may require different compiler flags. One of […]

Customizing Parallelware Trainer through environment variables
Starting with version 1.4.0, Parallelware Trainer can be customized using environment variables. This is particularly helpful in deployments using a multi-user license or when certain development packages are installed in non-standard locations (e.g. MPI headers being located in /opt/mpi/include instead of in /usr/include/mpi). Customizing license file location When looking for a license file, Parallelware Trainer […]
Defects and recommendations for parallelism
Implementing parallel software is hard. On top of all the kinds of bugs that may be present in sequential code, parallel code can also suffer from race conditions. A race condition exists when several threads access the same data at the same time and at least one of them writes to it. Opening the door […]
Fixing defects in parallel code: an OpenMP example
Parallelware Analyzer provides a set of tools covering the most challenging steps of your parallel development workflow. Join the Parallelware Analyzer Early Access Program to get access to the tools for free. In this post, we present the pwcheck tool which provides a static code analyzer to ensure that your code is defect-free and compliant […]
