Definition of Computational Science
Computational science is
a rapidly growing multidisciplinary field that
uses advanced computing capabilities to
understand and solve complex problems.
•Three distinct elements:
– Driven by the underlying
science/engineering/humanities problems;
– Solve the problems through simulations;
– Using advanced computing technologies
systems and infrastructure;

Hey, I am a CS guy
Something Interesting
HPC (solve a large scale problem in a
second?)
Information sharing (Everyone in the world
should see my results !!!)
Information analysis (now I am sure I will not
run into a black bear if I camp here!)
