1 1 AMS 200 Week 3 Computing Resources and Electronic Resources Hongyun Wang

2 2 SOE Computing Resources  Unix/Linux Servers Compute cluster Interactive servers Compute servers  Workstation Labs BE 308 and BE 316 E2 205  Wireless Network SOE-NAT (retiring soon) SOE-WPA  Printing Where can I print? How can I set up my laptop to print?

3 3 SOE Computing Resources (continued)  Policies Campus-wide policies for use of UCSC computing facilities SOE computing policies Penalties for violation  Requesting Support IT request BSOE helpdesk ITS support center

4 4 AMS Computing Resources  It is housed in BE 250.  IP address:grape.cse.ucsc.edu  It has 48 core processors.  Each processor is 2.33GHz with 2GB RAM.  It has Fortran compiler, C compiler and MPI (Message Passing Interface).  It has Matlab, IDL (Interactive Data Language), LApack … AMS Cluster: grape

5 5 More Computing Resources  SOE Webmail  UCSC Webmail  Setting up a vacation message  Setting up forwarding  Poster printing

6 6 Computing Software Matlab: a programming language for matrix-vector operations, with good graphics and visualization capabilities Maple: a programming language for symbolic computation Mathematica: not licensed by SOE

7 7 Examples of Matlab Plotting curves and surfaces Run “plot_fx.m” to see how to plot curves. Run “plot_fxy.m” to see how to plot a surface. Run “plot_Cities_pop.m” to see how to read in data, plot populations of 6 cities vs time, and use legend to label curves. Online Matlab manuals

8 8 Examples of Matlab (continued) Visualization of motion GUI (Graphical User Interface) First run “calc_2body.m” to generate the numerical solution. Then run “visualize_1.m” to visualize the motion. Run “ODE_4.m” to use the GUI. Run “demo_color.m” and / or run “demo_grayscale.m” to see the effect of image compression.

9 9 More Programming Languages HTML (Hyper Text Markup Language): -- learn it by reading other webpages R: -- Professor Kottas will talk about it Example: Professor Draper’s webpage IDL (Interactive Data Language): -- you will learn it later from Professors Brummell and Garaud if …

10 10 Electronic Resources  Online journals  Off-campus access  Book catalogs (cruzcat & Melvyl)  Articles & databases Library: SOE Courses: UCSC Searchable Schedule of Classes: https://pisa.ucsc.edu/prd/sr0060/ Online Campus Maps:
