Much of the software developed by CSM is available for free download from Netlib. Netlib, a collection of mathematical software, papers, and databases, is operated by ORNL and the University of Tennessee, Knoxville.


ATLAS (Automatically Tuned Linear Algebra Software) is an approach for the automatic generation and optimization of numerical software.


CUMULVS (Collaborative User Migration, User Library for Visualization and Steering) is a software infrastructure for the development of collaborative environments.

Electronic notebook

The electronic notebook is an important tool for scientists and engineers doing remote experimentation and collaboration.


OSCAR (Open Source Cluster Application Resources) is a snapshot of the best-known methods for building, programming, and using clusters. It consists of a fully integrated and easy-to-install software bundle designed for high-performance cluster computing. Everything needed to install, build, maintain, and use a modestly sized Linux cluster is included in the suite, making it unnecessary to download or even install any individual software packages on your cluster.


PVM (Parallel Virtual Machine) is a software package that permits a heterogeneous collection of Unix computers hooked together by a network to be used as a single large parallel computer. The software is very portable. The source, which is available free through netlib, has been compiled on everything from laptops to Crays.


The ScaLAPACK project is a collaborative effort involving several institutions and comprises four components: dense and band matrix software, large sparse eigenvalue software, sparse direct systems software, and preconditioners for large sparse iterative solvers.
