TeraChem is the first computational chemistry software program written completely from scratch to benefit from the new streaming processors such as Graphics Processing Units (GPUs). The computational algorithms have been completely redesigned to exploit massive parallelism of CUDA-enabled NVIDIA GPUs. The original development started at the University of Illinois at Urbana-Champaign. Due to the great potential of the developed technology, this GPU-accelerated software was subsequently commercialized. Now it is distributed by PetaChem, LLC located in the Silicon Valley.[1] The software package is under active development and new features are released frequently.

Core features

Very fast ab initio molecular dynamics and density functional theory (DFT) methods for nanoscale biomolecular systems with hundreds of atoms are arguably the most attractive features of TeraChem. Its affinity to extreme performance is also exemplified in the TeraChem motto "Chemistry at the Speed of Graphics".[2] All the methods used are based on Gaussian orbitals, a choice made to improve performance on the limited computing capacities of modern computer hardware. More comprehensive list of features can be found on the company's website or in the userguide.

Press coverage

Media

The software is featured in a series of clips on its own YouTube channel under "GPUChem" user.

Major release history

2012

Full support of polarization functions: energy, gradients, ab initio dynamics and range-corrected DFT functionals (CAMB3LYP, wPBE, wB97x)

2011

Alpha version with the full support of d-functions: energy, gradients, ab initio dynamics
Beta version with polarization functions for energy calculation (HF/DFT levels) as well as other improvements.
This version was first deployed at NCSA's Lincoln supercomputer for NSF TeraGrid users as announced in NCSA press release.

2010

The very first initial beta release was reportedly downloaded more than 4,000 times.
