Ninja


Description

NINJA Logo Ninja is a smart network noise injector for quickly exposing unindended MPI message races. Ninja uses innovative newtork noise injection techniques to increase the chance for a racy, incorrect MPI message matching within the target MPI application. Ninja has been shown to reproduce unsafe message races consistently within large production applications and can do this up to two orders of magnitude faster than the traditional testing approach (i.e., random noise injection).


Software

Ninja is open-source software and can be obtained on GitHub .


Quick Start

Ninja maintains an up-to-date package in the Spack develop branch, which builds all dependencies and Ninja itself from the current head of the master branch:

$ git clone https://github.com/LLNL/spack
$ spack/bin/spack install pruners-ninja

If you already have Spack, you can omit the first line.

Please refer to the instructions in README.md.
