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.

an ‘infrastructure and research network’

Mission:

connect those who develop simulations with those who use them in research

bridge disciplines

enable new modes of research, education, and collaboration

Key strategy:

“cyberinfrastructure”

computational science and engineering

Three reasons to simulate:

1) to explore uncharted territory

2) to resolve well-posed questions

3) to make good design choices

Two kinds of results:

1) answers and understanding

2) software

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

21

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
