repository has always been up to date.) An important
one to study is
CUDA Demo 4: All-to-All Memory Access Patterns
The code includes comments that explain thread assignment and
array element access. That must be understood to answer
questions about amount of memory accessed.

Deadline for Homework 2 changed to evening of 10 October
(technically, the wee hours of 11 October).
For Homework 2 pay attention to the following: (1) The code
instantiates three Cone objects, one for the big brown thing, one for
the chain links, and one for debugging. Any variables declared in the
global scope will apply to all instances of Cone, which probably isn't
want you want. (The cones have different geometries and so they cannot
share buffer objects.)
(2) When glDrawArrays is used, element i of the
normal array is used for element i of the vertex array. The
code in render_proba does not use glDrawArrays, it
uses glBegin instead and so it takes advantage of the fact
that you can specify a normal once and use it for multiple vertices.
8 October 2013, 16:23:30 CDT
Additional info about Homework 2
The solution to Problem 2 should be put in
. That routine has some code to demonstrate
the use of automatically sized arrays. The demo code should
be deleted before you put your solution in.
To switch between the render code for part (a) and (b) press
the 'v' key. To change the level of detail (opt_lod
press the 'TAB' key until "Level of Detail" appears near the
upper-left. The press the '+' and '-' keys to change the value.

Here is a possible cause of the login problems: Once a small
number of login attempts fail the account will be locked,
and further attempts to log in will fail without explaining why.
The login attempt limit has been increased to ten, and the lockout
time is ten minutes (I do not know what it was before). I apologize
for the tedium and frustration this must be causing. I agree
that there is no reason to force a random mixed-case/digits/characters
password for a system with a secret hash and a small login attempt limit.
work with our sysadmin so that next semester passwords will
be easier to type.
6 September 2013, 12:27:57 CDT
Many students have been experiencing login problems. I will
try to investigate the cause. In the mean time make sure
that you are logging into on of the listed machines (see previous
what's new entry), make sure Caps Lock is not pressed,
and be sure to distinguish a lower-case ell from the digit 1,

Updated list of machines that can be used for assignments, the
