Cyberinfrastructure – A Unifying Concept
Cyberinfrastructure =
resources
(computers, data storage,
networks, scientific
instruments, experts, etc.)
+ “glue”
(integrating software, systems,
and organizations).
NSF’s “Atkins Report”
provided a compelling
vision for integrated
Cyberinfrastructure

A Deluge of Data
•
Today data comes from everywhere
•
•
•
•
•
•
•
And is used by everyone
•
•
•
•
•
“Volunteer” data
Scientific instruments
Experiments
Sensors and sensornets
Computer simulations
New devices (personal digital devices,
computer-enabled clothing, cars, …)
Data from
sensors
Data
from
instruments
Data from
simulations
Researchers, educators
Consumers
Practitioners
General public
Turning the deluge of data into
usable information for the research
and education community requires
an unprecedented level of integration,
globalization, scale, and access

Impact on Technology: Data and Storage are
Integral to Today’s Information Infrastructure
• Today’s “computer” is a
coordinated set of
hardware, software, and
services providing an
“end-to-end” resource.
• Cyberinfrastructure
captures how the
research and education
community has
redefined “computer”

Better Neurosurgery Through
Cyberinfrastructure
Radiologists and neurosurgeons at
Brigham and Women’s Hospital,
Harvard Medical School exploring
transmission of 30/40 MB brain
images (generated during surgery)
to SDSC for analysis and alignment
•
•
•
PROBLEM: Neuro-surgeons
seek to remove as much tumor
tissue as possible while
minimizing removal of healthy
brain tissue
Brain deforms during surgery
Surgeons must align preoperative
brain image with intra-operative
images to provide surgeons the
best opportunity for intra-surgical
navigation
Transmission repeated
every hour during 6-8
hour surgery.
Transmission and
output must take on
the order of minutes
Finite element simulation on
biomechanical model for
volumetric deformation
performed at SDSC; output
results are sent to BWH where
updated images are shown to
surgeons

Preserving Data over the Long-Term
SAN DIEGO SUPERCOMPUTER CENTER
UCSD
Data Preservation
•
Many Science, Cultural, and Official
Collections must be sustained for the
foreseeable future
•
Critical collections must be
preserved:
•
•
community reference data
collections (e.g. Protein Data Bank)
•
irreplaceable collections
(e.g. field data – tsunami recon)
•
longitudinal data
(e.g. PSID – Panel Study of
Income Dynamics)
No plan for preservation often
means that data is lost or damaged
“….the progress of science and useful arts …
depends on the reliable preservation of
knowledge and information for
generations to come.”

Key Challenges for Digital Preservation
• What should we preserve?
•
•
What materials must be “rescued”?
How to plan for preservation of materials by
design?
• How should we preserve it?
•
•
•
Formats
Storage media
Stewardship – who is responsible?
Print media provides easy
access for long periods of time
but is hard to data-mine
• Who should pay for preservation?
•
•
•
The content generators?
The government?
The users?
• Who should have access?
Digital media is easier to data-mine but
requires management of evolution of media
and resource planning over time
