Cambridge Structural Database


The Cambridge Structural Database (CSD) contains complete structure information on hundreds of thousands of small molecule crystals. The Cambridge Crystallographic Data Centre (CCDC) is a suite of programs for CSD search and analysis. The Cambridge Crystallographic Data Centre Home Page has additional information.


Several versions of the software package are available at OSC. Search for csd in this list:

TURBOMOLE is an ab initio computational chemistry program that implements various quantum chemistry algorithms. It is developed at the group of Prof. Reinhart Ahlrichs at the University of Karlsruhe.


GLPK (GNU Linear Programming Kit) is a set of open source LP (linear programming) and MIP (mixed integer problem) routines written in ANSI C, which can be called from within C programs. 

Availability & Restrictions

GLPK is available to all OSC users without restriction. 

The following versions are available on OSC systems:

Managing Your Project

Principal Investigators of OSC projects are responsible for updating their authorized user list, their outside funding sources, and their publications and presentations that acknowledge OSC. All of these tasks can be accomplished through the ARMSTRONG portal (https://armstrong.osc.edu). PIs are also responsible for monitoring their project's Resource Unit balance and for submitting a proposal to the Allocations Committee of the Statewide Users Group before the balance goes negative.


CFX is a computational fluid dynamics (CFD) program for modeling fluid flow and heat transfer in a variety of applications.

Availability and Restrictions

CFX is available on Oakley and Glenn Clusters. The versions currently available at OSC are:

Quantum Espresso

Quantum ESPRESSO is a program package for ab-initio molecular dynamics (MD) simulations and electronic structure calculations.  It is based on density-functional theory, plane waves, and pseudopotentials.
