Engineering and Computing

• Engineering has a deep and long-standing connection with computing– Computational modeling, data, simulation, optimization

pervasive in all fields of engineering– Sensors, networks and computation deeply integrated

into engineered systems, manufacturing, and services– Engineering Directorate also supports research to

enable advances in computing

HPC and Bio-Engineering• First principles modeling of biomolecular systems

– Protein folding, complexes, ion channels, reaction kinetics• From genome annotation to reverse engineering of biological systems

– Metabolic network reconstruction– Regulatory network analysis and reconstruction– Populations and ecosystems

• From computational molecular biology to computational cell biology– Whole cell modeling– Tissue and organ modeling– Virtual organisms

• Bioengineering– Structural, electrical, and physiological modeling

HPC in Power Systems and Smart Grid• HPC is primarily for dynamic simulation/operations studies

of the power grid Ø Off-line – simulation environment for large scale systems to evaluate designs and proposed controls

under different conditionsØ On-line –

• faster than real-time simulation to investigate large number of contingencies (outages, events);• fast control calculation in case of imminent risk to the grid

• ChallengesØ Extreme scale (potentially millions of components)Ø Large geographic reachØ Modeling and data validityØ Integrating real-time measurements with simulation

ENG & HPC: Turbulence“Turbulence occurs over a wide range of scales. The two most resource-intensive approaches are direct numerical simulation (DNS) which resolves all scales, and large eddy simulation (LES) which resolves only the large scales but models the small scales. The largest DNS performed on Blue Waters at UIUC uses over half a trillion grid points and over 200,000 CPU cores.”

“A realistic simulation of rain formation, involving atmospheric thermodynamics, phase change, particle inertia, humidity, and radiative heat transfer, would be a worthy Exascale problem that has very significant impact. It is clear that fluid dynamics has a leading role in this endeavor.”

ENG & HPC: Integrated Systems Advanced Computing Challenges*

1. Optimum process synthesis and design of systems that span multiple temporal and spatial scales2. Optimum product/molecular design3. How energy and healthcare systems, both of which are complex systems with multiple stakeholders, will evolve at the product, process and supply chain levels as we try to address the national grand challenges: 4. Impact of uncertainty on all of the above mentioned open challenges

Some HPC issues in Engineering Research• Need for development of dedicated software with capabilities beyond those

available in commercial packages. Development and utilization of the next generation software should involve partnerships between computer scientists, domain scientists, and hardware experts.

• Multiscale/multiphysics computational resources are relevant to several programs and are not broadly available (mostly research level codes that are not ready nor available for distribution and broad adoption)

• Data transfer and visualization from supercomputing facilities to local resources (desktop) is often a challenge and a bottleneck in research

• HPC in real-time is still a challenge, given limitation in data transfer. If available, how would that affect how engineering research is performed?

• If more real-time large-scale simulation using cloud resources were conducted, could we have more environmentally friendly critical infrastructure?
