objectives
in this talk, I would like to:
1) Tell you who we are, what we do, and why we needed
cyberinfrastructure.
2) Describe nanoHUB.org - explain what is it is and how we
are using it.
3) Identify a few challenges and opportunities.

Network for Computational Nanotechnology
Mission:
NCN@Norfolk State
NCN@UTEP
NCN
NCN@Berkeley
connect those who develop
simulations with those who use
them in research
bridge disciplines
NCN@NU
NCN@Purdue
NCN@UIUC
enable new modes of
research, education, and
collaboration
Key strategy:
“cyberinfrastructure”
an
‘infrastructure and
research network’

computational science and engineering
Three reasons to simulate:
1) to explore
uncharted
Two
kinds ofterritory
results:
2) to resolve
well-posed
questions
1) answers
and
Twounderstanding
types of scientists/engineers:
3) to make
design choices
2) good

outcomes
1) promote the diffusion of knowledge
2) give a researcher impact
3) provide a new avenue for “publication”
4) facilitate the use of simulation in the classroom
5) promote collaboration across disciplines

issues and challenges
1) finding content in a growing collection
2) permanence of content
3) quality of content
4) handling data (in addition to simulation tools and
educational / training resources)
5) intellectual property
6) financial model for sustainability
7) people issues
