Also provided at this site are some descriptions of the planned multiscale methodology. The effort is currently being aimed at polymeric systems. This code is still very early in the design phase. At present it can be considered an interesting PDB file viewing tool and fullerene editor, but in the long run it is planned to be a nanocad utility. The code is distributed under GNU public license and is freely downloadable from the Web site.
Some documentation is available online, including some nicely illustrated tutorials.
Lots of methodological detail is provided. The site contains some nice overviews and a selection of papers on the topic downloadable in postscript. Sample inputs and outputs are also provided. It is currently available on SGI, IBM and Linux platforms, exhibiting fairly impressive scalability at the Hartree Fock level, and with a special new implementation of MP2 theory. The code is available for free download, as are some validation test cases.
