CUDA Spotlight
GPU-Accelerated Multi-Phase Flow Simulations
This week’s spotlight is on Dr. Mehdi Raessi, Assistant Professor in the Department of Mechanical Engineering at University of Massachusetts-Dartmouth.
NVIDIA: Mehdi, tell us about your research.
Dr. Mehdi RaessiMehdi: The focus of my research is primarily on multi-phase flows and free-surface flows with phase change. We develop computational algorithms and flow solvers, and use them to study industrial and research applications that involve multi-phase flows.

Examples include materials processing (thermal spray coating and casting), energy systems (both renewable and conventional), and environmentally friendly or "green" refrigeration systems.
NVIDIA: What role does GPU computing play in your work?
Mehdi: Our numerical algorithm for solving the fluid flow equations involves a step in which we solve a large system of linear equations to compute the pressure field. That single step can take from 50 to 99.9 percent of the total simulation time! As we increase the number of grid points in our simulations, the pressure solution step takes a larger percentage of the total simulation time.

To speed up this task, my graduate student, Stephen Codyer, ported the pressure calculations to the GPU. His tests show that the GPU-accelerated solver can run a 3D simulation with over 28 million grid points 15 times faster (compared to performing the same calculation on the CPU). My colleague, Prof. Gaurav Khanna, from our Physics Department, helped us a lot in this project and shared his extensive experience in GPU computing.
NVIDIA: What future applications can you envision in your research area?
Mehdi: As we all know, energy and the environment have become the most pressing issues in the world. Addressing these issues requires new technology and drastic changes in the ways that we use our energy resources. After events like the oil spill in the Gulf of Mexico and the Fukushima Daiichi nuclear disaster, I think everyone agrees that we should plan to use energy resources that have low potential to cause catastrophic events.

We have begun projects that are targeting these issues. With GPU-accelerated computational tools, we are now able to study much larger problems at a level of detail that was not feasible before. These simulations can lead to new energy devices that are more efficient and have less environmental impact. I believe the capability to run faster and faster simulations with GPUs will one day enable us to predict, respond to and mitigate catastrophic events.

Test Drive the Tesla MD SimCluster back to the top
Want to test drive a GPU? Try the new Tesla Molecular Dynamics SimCluster, which is preconfigured to accelerate AMBER or NAMD. All you need to do to start a simulation is load your models. To test drive, visit www.nvidia.com/simcluster or email mdsimcluster (at) nvidia.com.
New CUDA Centers Announced
Congrats to all the new CUDA Research Centers and CUDA Teaching Centers, including Carnegie Mellon/Silicon Valley and the University of Edinburgh. For the complete list of newcomers, see this recent blog post: http://blogs.nvidia.com/2011/09/new-cuda-research-and-teaching-centers-announced/

MATLAB Acceleration on GPUs
Using MATLAB for GPU computing is ideal for engineers and scientists who want to take advantage of GPUs without low-level C or Fortran programming. Register for a free webinar on October 27 to learn how CUDA-enabled GPUs can help accelerate MATLAB computations: http://bit.ly/ondzzC.
For more info about GPU computing in MATLAB, see this recent MATLAB Digest article: http://bit.ly/pOiZg6.

Mini-Supercomputer from HP
The new GPU Starter Kit from HP provides a ready-to-use GPU computing cluster, straight out of the box. It combines eight HP ProLiant SL390 G7 servers (based on 24 Tesla M2070 GPUs) with 16 CPUs. For info, visit www.nvidia.com/docs/IO/43399/NV-Tesla-Starter-Kit.pdf or email Hpc-sales (at) hp.com.

Running CUDA on x86
In Dr. Dobb’s newsletter, Rob Farber writes: "Recent developments allow CUDA programs to transparently compile and run at full speed on x86 architectures. This advance makes CUDA a viable programming model for all application development, just like OpenMP. The PGI CUDA C/C++ compiler for x86 (from the Portland Group Inc.) is the reason for this recent change in mindset."
