PHYSICS 141/241


Laboratory Session I: OS X Unix and Visualization

1. The Computational Physics Laboratory

As an important part of the new Computational Physics Program, in a collaborative effort with UCSD Academic Computing Services, we built a computational physics laboratory which is located at 4623 Mayer Hall. The laboratory has a farm of modern workstations with scientific visualization and multimedia capabilities, access to a server of sufficient computational power and disk storage to implement the software gracefully, and auxillary equipment. The configuration of the workstation platform was designed to be flexible with fast ethernet connection providing access to the campus and the Internet.

  • 6. Industry Strength Data Visualization: IBM Data Explorer  (OpenDX)

    This professional grade visualization platform is in the public domain now. We will adapt this package as our data visualization package. The introductory manual (Quickstart Guide) is available now for a first look. You can read the manual in HTML format using your Netscape browser. You can also download the manual in postscript and PDF format.
    The IBM Documentation for Data Explorer exists in different formats.

    Quickstart Guide: This guide presents a "hands on" introduction to Data Explorer and is designed to help you start working with it immediately.
