SUPERCOMPUTING CHALLENGE KICKOFF 2015 A Model for Computational Science Investigations Oct 2015 © challenge.org Supercomputing Around Us: Sensors and Data1

Computational Science is the use of mathematics and computers to model “real world” problems in science, and conduct simulation experiments. Oct 2015 © challenge.org Supercomputing Around Us: Sensors and Data2 Computational Science?

Computational Science (CS) complements, but does not replace, field experimentation in scientific research. Each approach is appropriate in certain situations. CS is ideally suited to exploration of problems which are too expensive, too dangerous, too difficult to control, too fast, too slow, too… etc. for extensive experimentation in the field. CS allows us to perform large numbers of experiments, using alternative scenarios with different inputs. This can be used for “what if” analyses, as well as output- driven solutions to complex problems. Oct 2015 © challenge.org Supercomputing Around Us: Sensors and Data3 Computational Science
