Physics 555B: Advanced Computational Physics: Course News 
This document will be updated throughout the course; entries are in reverse chronological order. 
1)
CLASS ON THURSDAY, APRIL 5 IS CANCELLED 2) THE TERM PROJECT PRESENTATION IS AS FOLLOWS TUESDAY APRIL 10
3) NOTES/GUIDELINES FOR PRESENTATIONS

An
updated version of the second homework that. modulo typos, is now
complete and final is available HERE. This version differs
from the last in that problem 2a) has now been specified. 
An
updated version of the second homework that now contains the third
question (in its entirety) is available HERE. The second question
is still incomplete vis a vis the specific numerical experiment that is
to be perfomed. 
As
per my earlier email, Robert has pointed out another, more significant
error in the Homework 2 handout. Specifically, the expression for
the exact solution for a "particle in a box" (currently, equation
(32)), had a sign error in the "complex exponential", i.e. exp( i (m pi)^2 t ) ... should have (and now does) read exp( i (m pi)i^2 t ) ... Also, in light of what I heard Robert mention to his classmates, please note that the "bare" expressions for the initial data/exact solution are unnormalized, so if you do use the exact solution (32), that solution will subsequently have to be norrmalized, using, for example, the instructorsupplied routine psi_normalize. . An updated version of the homework is available HERE. 
Dominic
has pointed out a typo in the first question of the second homework, on
the second page of the handout. Specifically, the phrase ... and for 0 <= t <= 0.5, will return ... should be replaced with .... and for 0 <= t <= 0.25, will return ... An updated version of the homework is available HERE. 
An
updated version of Homework 2 is now available for download HERE.
This version is still incomplete, but will allow you to get working on
the second of the three problems in the assignment. 
A
preliminary version of Homework 2 is now available for download HERE.
Note that this version contains only the first of the three problems
that will eventually constitute the assignment. Updated versions
containing the other questions will be posted as they become available. 
It
has been pointed out that in the first question on Homework 1, I did
not explicitly state that all of the finite difference approximations,
including the O(h^4) approximations to the first and second derivatives
are to be CENTRED. My
apologies for the omission, and for the confusion and/or extra work it
has caused. The homework handout has been updated accordingly. 
Regular
emacs as opposed to xemacs has been installed on the lnx machines. Additionally links to both the LAPACK and BLAS (Basic Linear Algebra Subprograms) source code directoies have been added to the course Notes page. Also note that lnx[123] is "unixese" for the three distinct lnx machines
I apologize for any confusion this notation may have caused, but, on the other hand, I suspect that lack of confusion on this issue is highly correlated with the degree to which the Unix Notes have been studied :) 
The
following accounts have now been created on the lnx[123].physics.ubc.ca machines: nahid, kehoe, marchand, mazur, petermc, rpatters, raiser With one exception (kehoe) the passwords for these accounts should be identical to the corresponding accounts on physics.ubc.ca. Mr Kehoe, your account on physics has expired, so you should visit Mary Ann Potts to have it reinstated, and then send me mail when you have done so. All students who have registered for the course should now have accounts on lnx[123]. Let me know if you have any problems logging in to those machines, either at the console, or via ssh. Also note that on your lnx accounts I have created a directory public_html. If you create the HTML file index.html, within that directory, you will be able to access said file via the STUDENT PAGES link from the course home page. I recommend that you use Composer (part of the Mozilla Web browser) or some other WYSIWYG HTMLeditor to create and maintain your Web page(s). 
Our
first class is scheduled for 9:30
AM, TUESDAY, JANUARY 9, 2007 in HENNINGS
309B. (NOTE THE ROOM!!)
You should be able to register for the course online, selecting PHYS 555B, section 206.
