Molecular Science Computing

Environmental molecular research is accelerated when combined with leading-edge hardware, efficient parallel software, accurate and predictive theories and visualization capabilities. Users are encouraged to combine computation with EMSL's state-of-the-art experimental tools that make an integrated platform for scientific discovery. See a complete list of Molecular Science Computing instruments.

The Molecular Science Computing (MSC) capability supports EMSL's flagship computing resources including:

  • Cascade, a supercomputer with theoretical peak performance of 3.4 petaflops, that came online in December 2013. See announcements about the current status of Cascade
  • NWChem, a molecular modeling software developed to take full advantage of the advanced computing systems installed. NWChem provides many methods to compute the properties of molecular and periodic systems by using standard quantum-mechanical descriptions of the electronic wavefunction or density.
  • GA Tools (Global Arrays Programming Models)
  • Ecce, a domain encompassing problem-solving environment for molecular modeling, analysis, and simulations, and
  • Aurora, a 15.8 Petabyte HPSS data storage system

EMSL employs a forward-looking strategy to maintain leading-edge supercomputing capabilities and encourages users to combine computational and state-of-the-art experimental tools, providing a cross-disciplinary environment to further research.
