The Tesla Bio Workbench consists of:
- A range of GPU-optimized bioscience applications for molecular dynamics- and quantum chemistry-based research, including: AMBER, GROMACS, LAMMPS, NAMD, TeraChem, VMD, and bioinformatics applications like CUDASW++ (Smith-Waterman), GPU-HMMER, and MUMmerGPU.
- A community site for downloading the applications, checking out the latest benchmarks, reading academic papers and tutorials, joining discussion forums with the application developers themselves and more.
- Details on the Tesla GPU-based workstations and clusters available worldwide for easy deployment of these applications.
Scientists have traditionally performed experiments in laboratories, where chemicals are combined, their interactions studied and their effectiveness measured. Advances in computational science have now enabled these experiments to be carried out using molecular dynamics and quantum chemistry simulation models, however these have typically required very large supercomputers with thousands of central processing units (CPUs).
By using the massively parallel CUDA architecture of NVIDIA GPUs, these applications can now be run 10-20 times faster, which means even a PC with Tesla GPUs can outperform a supercomputer.
"We are working on a new GPU-based technique in the VMD molecular dynamics visualization software that investigates how small molecules like oxygen and CO2 migrate inside proteins. This research is critical in the study of enzymatic reaction mechanisms", stated John Stone, senior research programmer, University of Illinois at Urbana-Champaign. "A simulation that takes 1 day to run on a GPU-based workstation would have taken 30 days to run on a CPU-based machine, rendering it impractical for real research."
"TeraChem is a powerful molecular modelling package whose calculations can guide the design of new drugs while avoiding wasted time synthesizing unpromising candidates", stated Todd Martinez, professor of physical and theoretical chemistry at Stanford University. "With TeraChem, calculations that would have taken days or weeks on a computer cluster can now be performed routinely on NVIDIA GPU-enabled workstations. This allows high-throughput computational screening and can accelerate the drug design process."
"Using AMBER to carry out simulations of a cellulose hydrolyzing enzyme called Cellobiohydrolaze-I, which is a key component in improving the efficiency of bio-ethanol production, we're seeing performance from a single NVIDIA GPU thats equivalent to a 10 node cluster", stated Ross Walker, Research Professor at the San Diego Supercomputer Center, UC San Diego.
"Researchers here are using the GPU-based NAMD molecular dynamics software to study how virus cells react to different drugs, including studying the effectiveness of drugs on the H1N1 virus", stated Klaus Schulten, Swanlund Professor of Physics, Director of the NIH Resource for Macromolecular Modelling and Bioinformatics and Co-director of the NSF Center for the Physics of Living Cells at University of Illinois at Urbana-Champaign. "NAMD running on 4 GPUs in a workstation can outperform 16 CPUs in a server farm."
"One of the future challenges of molecular simulation is to enable automated drug screening. We have traditionally used GROMACS to calculate the binding of drugs to membrane proteins by using large clusters, but this is both a costly and complex process", stated Erik Lindahl, associate professor at the Center for Biomembrane Research at Stockholm University. "We are now adding GPU support because a single GPU can be up to 4-5X faster than a CPU for most normal simulations. Within a few years, we expect workstations equipped with a handful of compute cards to have taken a huge part of the market and because of this we see NVIDIA as a critically important partner."
