Computational Physics Dr. Guy Tel-Zur Version :40

Agenda Administration MHJ Chapter 10: MC methods in Statistical Physics More on VisIt: – The Silo file format – A demo program – Creating a movie More HPC stuff DLA Demo: AWS – HPC Instance for Parallel Computing and Cellular Automata / NKS demo on the cloud Home assignment #3

Final Projects Please hurry to choose a topic

Visualization: The Silo file format References: – Download: (BSD License) – – science.le.ac.uk/format/silocode.shtml science.le.ac.uk/format/silocode.shtml

Visualization: A demo program Use VirtualBox  Ubuntu  Install Silo and VisIt Installation was not smooth on Ubuntu 10.4, I had to install libstdc++5 manually (an older version) Let’s look at “wave.c” – Open DevC++ with: C:\Users\telzur\Documents\My Talks\MIL_OSS\silo\silo-4.8-bsd\tests\wave.c

Silo Discuss in class the wave.c program Run the program on the Virtual Machine Make plot using VisIt Make a mpeg movie!
