Quantum Chemistry on GPUS

TeraChem is a powerful general-purpose quantum chemistry package developed in our group. By exploiting graphical processing units and designing the code from the ground up to expose parallel concurrency, we are able to accelerate Hartree-Fock and DFT calculations by several orders of magnitude over CPU based programs. This allows ab initio quantum mechanical calculations to be routinely performed on extremely large systems.
