We are heavy users of two supercomputing facilities: SDSC and NCSA's Origin2000.
Currently, there are two national networks of supercomputing
groups studying the future of the Internet and remote high performance
research. One group is the Alliance and the other is the
National Partnership for Advanced
Computational Infrastructure (NPACI). The Alliance has an on-line magazine
"Access" which is a window to the work done
in the group.
Our group works closely with Professor Tomas
Arias of Cornell, a former student of Professor Joannopoulos'.
The main electronic density functional code we use is the DFT++ package.
