MapReduce-MPI Library

MapReduce-MPI Library

MapReduce-MPI (MR-MPI) library is an open-source implementation of MapReduce written for distributed-memory parallel machines on top of standard MPI message passing.

The MR-MPI library was developed at Sandia National Laboratories, a US Department of Energy facility, for use on informatics problems. It includes C++ and C interfaces callable from most hi-level languages, and also a Python wrapper and our own OINK scripting wrapper, which can be used to develop and chain MapReduce operations together. MR-MPI and OINK are open-source codes, distributed freely under the terms of the modified Berkeley Software Distribution (BSD) License. See this page for more details.

The authors of the library are Steve Plimpton and Karen Devine, who can be contacted at sjplimp at sandia.gov and kddevin at sandia.gov.

The MR-MPI WWW site is hosted by Sandia, which has this Privacy and Security statement.
