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 often.

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 user guide.[3]

Press coverage

  • Chemical and Engineering News (C&EN) magazine of the American Chemical Society first mentioned the development of TeraChem in one of its Fall 2008 issues. Then, GPU-accelerated computing was at the level of a very extravagant science.[4]
  • Recently, C&EN magazine has a feature article covering molecular modeling on GPU and TeraChem.[5]
  • According to the recent post at the Nvidia blog, TeraChem has been tested to deliver 8-50 times better performance than General Atomic and Molecular Structure System (GAMESS). In that benchmark, TeraChem was executed on a desktop machine with four (4) Tesla GPUs and GAMESS was running on a cluster of 256 quad core CPUs.[6]
  • TeraChem is available for free via GPU Test Drive.

Media

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