  1. CS4414 Issues in Scientific Computing Alexey Onufriev Departments of CS and Physics VT

  2. Computational Science now: a paradigm shift Experiment From the Greeks to the recent past, e.g. figuring out Earth’s radius theory Now Computation

  3. How it works Image credit: http://www.physics.orst.edu/~rubin/INSTANCES/index.html

  4. Computational Science/Scientific Computing in the grand scheme of things. Natural Science Computer Science Computational Science Math Applied math Computational Science: solving science problems with computers Pure CS: software and hardware, Stand-alone algorithms (just like math)

  5. Examples • Human Genome • Stealth Fighter • MRI • LHS • Weather Forecasts • Protein Folding • ??? (input from class)

  6. What can computational science accomplish? • Speed up finding a solution • Find additional solutions • Find solutions otherwise impossible to find • Discover new fundamental laws???

  7. What is this class about? • Gives you a taste of what scientific computing is, via realistic hands-on project (and homeworks). • Shows you how scientific computing is different from programming or math. • Introduces a number of useful tools and concepts • Teaches you how to work as part of a team • Will give you a glimpse of what computation can do for biology and modern medicine

  8. What this class is not: • In-depth parallel computation course (e.g. CS5234) • In-depth numerical methods, where you learn everything there is to know about one or two common methods (e.g. finite elements, CS5484). • Focused on high performance libraries (e.g. LINPACK), you will get a good idea of what these are.

  9. Specifics. Course structure. • Class websitehttp://courses.cs.vt.edu/cs4414/S13/

  10. The nitty-gritty • By next class: • Access to a unix machine • Install Mathematica 9 (VT network software) • Pre-reqs, force adds

  11. Enjoy!
