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.

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.

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

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 15
-
20 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 CONCLUSION


Data supports hypothesis


Substrate increases,
macroinvertebrates increase


Substrate helps macroinvertebrates


Sediments and silt reduce health of
substrate
