Sun Workshop
We have an excellent environment for exploring, debugging and optimizing
codes on rohan - workshop
Purpose: Introduce Linear System solving A x = b
Our computational experiments for this course involve both synthesis and
analysis. I would like you to begin the synthesis portion by
reading through the following materials. Later you will be asked to
devise a specific experiment to produce values that you will analyze,
comprising the analysis portion of the assignment. Since we do
not have Math 542 or Math 693b as a prerequisite, many of you will be
unfamiliar with the discretization of a region to allow the
approximation of the solution to a partial differential equation.
Therefore the materials below provide this background in a manner focused
on our needs in CS 575 Supercomputing.
On Monday, March 5, I will distribute the next assignment, which will involve a
computational experiment (using basic codes that will be available then),
examining the output from these codes and writing a report discussing
your discoveries (report template and specific will be available then).
