"Parallel MATLAB: Single Program Multiple Data",
a lecture on parallel MATLAB and the SPMD command
for running programs on Virginia Tech's Ithaca cluster,
given 25 June 2010.
Some information for those interested in attending the lecture
is included in matlab_spmd_2010_vt.txt.
The files used for this presentation include
-
cg_it.m,
carries out the conjugate gradient iteration;
-
cg_spmd.m,
uses CG_IT to seek a solution of an eigenvalue problem;
-
channel.png,
an image of a 1x1x3 channel, divided into tetrahedral elements.
-
configuration.png,
a menu that displays some properties of a configuration.
-
fem2d_heat_steady.png,
a surface plot of the solution to a steady heat equation in 2D.
-
fem2d_heat_steady_grid.png,
a schematic of a very small finite element grid divided
among parallel workers.
