Deterministic OpenMP for Race-Free Parallelism

Free registration required

Executive Summary

Recent deterministic parallel programming models show promise for their ability to replay computations and reproduce bugs, but they currently require the programmer to adopt restrictive or unfamiliar parallel constructs. Deterministic OpenMP (DOMP) is a new deterministic parallel environment built on the familiar OpenMP framework. By leveraging OpenMP's block-structured synchronization annotations, which are largely compatible with the constraints of a deterministic model, DOMP eases the parallelization of legacy serial code and preserves substantial compatibility with OpenMP software.
