Owens, Pitzer

The Owens and Pitzer clusters have access to the DDN Infinite Memory Engine (IME), a fast data tier between the compute nodes and the /fs/scratch file system. IME is a Solid State Disk (SSD) that can act as a cache and burst buffer to improve the performance of the scratch file system.


Transmission3d is a 3-dimensional, multi-body gear contact analysis software capable of modeling complex gear systems developed by Ansol (Advanced Numeric Solutions). Multiple gear types, including: Helical, Straight Bevel, Spiral Bevel, Hypoids, Beveloids and Worms can be modeled. Multiple bearing types, as well as complex shafts, carriers and housings can also be modeled with the software. A variety of output data options including tooth bending stress, contact patterns, and displacement are also available.



The Natural Bond Orbital (NBO) program is a discovery tool for chemical insights from complex wavefunctions. NBO 6.0 is the current version of the broad suite of 'natural' algorithms for optimally expressing numerical solutions of Schrödinger's wave equation in the chemically intuitive language of Lewis-like bonding patterns and associated resonance-type 'donor-acceptor' interactions.


Rosetta is a software suite that includes algorithms for computational modeling and analysis of protein structures. It has enabled notable scientific advances in computational biology, including de novo protein design, enzyme design, ligand docking, and structure prediction of biological macromolecules and macromolecular complexes.



Desmond is a software package that perform high-speed molecular dynamics simulations of biological systems on conventional commodity clusters, general-purpose supercomputers, and GPUs. The code uses novel parallel algorithms and numerical techniques to achieve high performance and accuracy on platforms containing a large number of processors, but may also be executed on a single computer. Desmond includes code optimized for machines with an NVIDIA GPU.
