OSC Overview Alan Chalker Ph.D. Program Director Ohio Supercomputer Center August 13, 2009

2 The Ohio Supercomputer Center Supercomputing. Computation, software, storage, and support services empower Ohio’s scientists, engineers, faculty, students, businesses and other clients. Networking. Ohio’s universities, colleges, K-12 and state government connect to the network. OSC also provides engineering services, video conferencing, and support through a 24x7 service desk. Research. Lead science and engineering projects, assist researchers with custom needs, partner with regional, national, and international researchers in groundbreaking initiatives, and develop new tools. Education. The Ralph Regula School of Computational Science delivers computational science training to students and companies across Ohio.

3 Supercomputing: Computational Infrastructure IBM expansion Opteron dual-core w/IBM Cell 9,500+ cores 24 TBytes memory 75+ teraflops Blend of 4, 8 & 16 core nodes –Large processor count –Large memory SMP jobs “Glenn” HPC System, expanded Summer 2009 Mass Storage 470 TBytes disk 80 TBytes tape NFS, PVFS, iSCSI

4 Networking: Ohio’s High-speed Backbone Consists of more than 1,850 miles of fiber-optic backbone Provides connectivity for Ohio’s colleges and universities, K-12 schools, public broadcasting and state government

5 Research: Designing land-speed race vehicle aerodynamics World's first hydrogen fuel cell- powered land speed race research vehicle Designed to beat Bullet 1 (electric battery) records –U.S. record clocked 314mph; world record is 272 mph Aerodynamics designed at OSC by OSU undergraduate student OSC staff assisted with meshing, batch processing and fluid-solid modeling of parachute deployment.

6 Research: Diagnosing fragile newborns in high-definition OSC, Nationwide Children’s Hospital (Columbus) and Adena Regional Medical Center (Chillicothe) are improving remote medical consultation. Through high-definition videoconferencing, specialists can now: –view distressed newborns with great clarity –examine detailed X-rays –take online electronic stethoscope readings –consult with attending physicians –also provides high-definition tele- visits to help reassure working families whose newborns have been transferred to Columbus for extended periods.

7 Education: Ralph Regula School of Computational Science The Ralph Regula School helps to ensure that Ohio has a workforce skilled in Computational Science –Computational Science: the use of computer modeling and simulation to solve complex business, technical, and academic research problems –Winner of national Krell Institute Undergraduate Computational Engineering and Science Award –Expanding undergraduate minor program to 14 colleges and universities –Associates of Science Degree program begins Autumn 2009 –Participating in development of Great Lakes Consortium virtual graduate school and national HPC University –Provides training to Ohio and national audiences

8 Education: Reaching more students at the K-12 level 2008 Summer STEM Engineering Academy funded by the Ohio Board of Regents –40 students and 10 teachers at OSU and Akron Summer Institute program for gifted high school students –~300 students over 19 years Young Women’s Summer Institute to encourage middle school girls to pursue science and math careers –~275 students over 8 years

SI: Twenty Years of Results Since starting in 1989, almost 300 students have participated Projects change as computing evolves An annual two-week residential program for gifted students (9 th -10 th grade) Hands-on project based learning using supercomputers, high-end workstations, and other resources Learn programming languages, parallel processing and visualization

SI: Example Projects Comet Project - Used MATLAB to process astronomical images to find comets using knowledge of how comets show up in the images and image processing techniques Molecular Dynamics - Studied protein structure and functions in the bird flu virus and simulated the interaction of bird flu fusion peptide with cell membrane using VMD and NAMD Gaming Project - Created multi-player game using internet protocols, Python programming language and Panda3D, a game engine

SI: Example Projects Network Forensics - Used Perl, Mysql, and Snort intrusion detection system to detect, analyze, and visualize cyber- attacks Thermodynamics - Learned to use statistical mechanics of a large number of atoms to study gases and used MATLAB to simulate an ideal gas in a container and create a visualization Parallel Processing - Made a program that can play a game of Risk and learn throughout the game which strategy works best via artificial intelligence algorithms

YWSI: Ten Years of Results 155 girls have participated Longitudinal study preliminary results –44 responses so far –80% reported greater interest in science since YWSI and agreed YWSI encouraged STEM careers –70% took additional science and math classes –75% more confident in math and science Two of the year 2000 girls are pursuing PhD’s in science and engineering Inquiry based –Allow for exploration and discovery –Focus on learning theory, terminology, and techniques as needed –Active participation in the learning process

Major questions –How do we measure watershed quality? –What impacts do people have on water quality? –Visit to Big Darby Creek to see how measurements are taken Watershed detectives – what is wrong in this watershed? Study of an Ohio watershed based on data from a research project for U.S. EPA YWSI: Studying a Watershed

ROCKY RIVER WATERSHED Is this watershed healthy or unhealthy? If it is unhealthy, what are the main impairments? By: Laura Hagy, Lydia Gray, and Elizabeth Chiu

ROCKY RIVER FACTS  Lorain, Medina, Summit, and Cuyahoga counties (near Cleveland)  Primary Uses  Cleveland-Hopkins International Airport  Golf Courses  Urban/Farming/Forest  Main impairment: Nutrient Enrichment

LAURA’S HYPOTHESIS When the health of the substrate increases the ICI or macroinvertebrate community increases in numbers also.

LAURA’S DATA ANALYSIS

LAURA’S CONCLUSION  Data supports hypothesis  Substrate increases, macroinvertebrates increase  Substrate helps macroinvertebrates  Sediments and silt reduce health of substrate
