DataRaceBench 1.3.2

DataRaceBench is a benchmark suite designed to systematically and quantitatively evaluate the effectiveness of data race detection tools. It includes a set of microbenchmarks with and without data races. Parallelism is represented by OpenMP directives. OpenMP is a popular parallel programming model for multi-threaded applications.

Note that some microbenchmarks use OpenMP 4.5 and 5.0 features. You may need a recent OpenMP compiler to compile them.

DataRaceBench also comes with an evaluation script ( The script can be used to evaluate the tools Helgrind, Archer, Thread Sanitizer, Intel Inspector, and Coderrect Scanner. In addition a parameterized test harness (scripts/ is available which allows to provide a number of different parameters for the evaluation. The test harness is used by the evaluation script with some pre-defined values.

Quick Start


Usage: ./ [--run] [--help] language

--help      : this option
--small     : compile and test all benchmarks using small parameters with Helgrind, ThreadSanitizer, Archer, Intel inspector.
--run       : compile and run all benchmarks with gcc (no evaluation)
--run-intel : compile and run all benchmarks with Intel compilers (no evaluation)
--helgrind  : compile and test all benchmarks with Helgrind
--tsan-clang: compile and test all benchmarks with clang ThreadSanitizer
--tsan-gcc  : compile and test all benchmarks with gcc ThreadSanitizer
--archer    : compile and test all benchmarks with Archer
--coderrect : compile and test all benchmarks with Coderrect Scanner
--inspector : compile and test all benchmarks with Intel Inspector
