CRI Poster Winner
April 14, 2009

The Computing Research Institute is pleased to announce that Rebecca Owston was selected as the CRI Poster award winner from the SIAM@Purdue Student Conference 2009 Poster Session. All poster presenters did a wonderful job and we appreciate all of the hard work that went into preparing/presenting for this event.

The title: Modeling of Forced Ignition and Combustion in Stratified Hydrogen Mixtures

Abstract:
In hydrogen direct-injection spark-ignition (DISI) engines the spatial and temporal ignition event is fixed by the spark plug placement and timing. In order to provide stable combustion the fuel-air mixture at the spark location has to be controlled in order to prevent misfire. Two-dimensional direct numerical simulations of a forced-ignition event in an initially quiescent mixing layer of hydrogen and air have been carried out at atmospheric pressure using detailed chemistry and mixture-averaged diffusion coefficients. Overall, this study primarily investigates the effect of initial spark placement within the flammability limits of hydrogen-air. Displacement and stabilization speeds of the propagating flame fronts have been computed along isocontours of water vapor representing 10% and 25% of the downstream equilibrium concentration.

Following the period of spark energy-addition the flame kernel is observed to bifurcate into twin triple flame structures that subsequently propagate towards opposite sides of the domain along the stoichiometric line. For all cases of successful ignition, transient spark effects are observed to dissipate within 0.2 milliseconds.

Please congratulate Rebecca on a job well done!

Purdue acquires power efficient supercomputer
June 10, 2008

Purdue University has acquired a SiCortex computer that can deliver high compute power to applications, with greater power efficiency. Purdue's SiCortex has 3240 computational cores, with 6 cores per chip running at 500 MHz, and an aggregate peak performance of 3.2 Teraflops/sec.

The total system memory is 4.3 TB (8 GB per node).

The SiCortex computer acquisition was initiated jointly by CRI and ITaP, with support by a large number of faculty. It was made possible through an award from Purdue's Provost with matching funds from a number of units on campus.

The SiCortex machine has a different system balance from traditional clusters in that it has slower processors and a fast interconnect, which is designed to enable high scalability. The system is currently being tested by early adopters who are interested in scaling their codes to large numbers of processors.

Purdue Team wins DoE PSAAP award
Purdue University has been selected by the Department of Energy as one of five Centers of Excellence whose primary focus will be on the emerging field of predictive science.

The new Center for Prediction of Reliability, Integrity and Survivability of Microsystems, or PRISM, will be led by Prof. Jayathi Murthy from Purdue's School of Mechanical Engineering. The Center will receive $17 million each over a five-year period under the Predictive Science Academic Alliance Program (PSAAP). PSAAP is managed by the DoE's NNSA.

Predictive science is the application of verified and validated computational simulations to predict the behavior of complex systems where routine experiments are not feasible.

In addition to developing models and software for large-scale simulations of micro-electromechanical systems (MEMS), Purdue's PRISM project will also develop methods associated with the emerging disciplines of verification and validation (V&V) and uncertainty quantification. The goal of these emerging disciplines is to enable scientists to make precise statements about the degree of confidence they have in their simulation-based predictions.

The other universities funded under this program are the California Institute of Technology, the University of Michigan, Stanford University, and the University of Texas at Austin.

The lead P.I. of the PRISM project, Prof Jayathi Murthy, and project team member, Prof Alexandro Strachan (MatSE) are both on CRI's Steering Committee. Faisal Saied from CRI and the Rosen Center for Advanced Computing is also part of the project team.

IWOMP 2008 Registration now open
The 2008 International Workshop on OpenMP (IWOMP 2008) will be held on the campus of Purdue University in West Lafayette, Indiana.

IWOMP is the premier opportunity to learn more about parallel programming with OpenMP, and to interact with OpenMP users and developers. The workshop also serves as a forum to present the latest research ideas and results related to OpenMP.

IWOMP 2008 will be a three-day event. The first day will consist of tutorials focusing on topics of interest to current and prospective OpenMP developers, suitable for both beginners as well as those interested in learning of recent developments in the evolving OpenMP standard. The second and third days will consist of technical papers and panel session(s) during which research ideas and results will be presented and discussed.

Purdue team wins NSF PetaApps award
Gerhard Klimeck from Purdue's School of Electrical and Computer Engineering and the Network for Computational Nanotechnology received a $1.6 million dollar NSF PetaApps award. This NSF program "seeks proposals to develop the future simulation, optimization and analysis tools that can use petascale computing to advance the frontiers of scientific and engineering research". The proposal entitled "Accelerating Nano-scale Transistor Innovation though Petascale Simulation" will add new capabilities to existing codes for modeling nano-electronic devices such as quantum dots and nanowires for the next generation of petascale computers. The use of the atomistic, quantum mechanical (QM) models like the Non-Equilibrium Green's Function (NEGF) leads to very large scale computations. The principal investigator developed NEMO1D, the first NEGF-based commercial-grade device simulator, and NEMO3D, which calculates electronic structure (no NEGF) for systems larger than 52 million atoms. The codes have been shown to scale to more than 16,000 and 8,000 cores, respectively. The project expects to extend the NEGF capabilities of NEMO1D with the NEMO3D electronic structure description to form the next generation engineering toolkit, OMEN.

Thomas Hacker from the College of Technology and Dongyan Xu from Computer Science are co-PI's on this award. Faisal Saied from CRI and RCAC is also part of the project team.

Purdue CFD code scales to over 16,000 processors
Steven H. Frankel, Professor of Mechanical Engineering has successfully run a computational simulation code his research group developed on 16,384 processors of an IBM Blue Gene/L computer. The code simulates turbulent flows with an emphasis on the development and application of "Large Eddy Simulation" to turbulent reacting flows, aeroacoustics, multiphase, and biological flows. "We were not yet able to run the largest job we set as our ambitious goal (8192^3 mesh) due to memory", Frankel said. However, running on up to 40,000 processors is now a next milestone, his group is working towards. For more information on Professor Frankel's research, see http://ristretto.ecn.purdue.edu/.
