matlab_parallel_2011_ajou, "Parallel Programming with MATLAB", a presentation to the Department of Mathematics, Ajou University, Suwon, Korea, given on 22 September 2011. I was hosted by Professor Hyung-Chun Lee.

An abstract for the talk is available in matlab_parallel_2011_ajou.txt.

The following files were used:

• compute.m, a MATLAB function, part of the MD program, which computes interparticle forces.
• fsu_logo.pdf, a logo.
• heat_equation.png, illustrates how the grid for the 2D heat equation might be divided into strips, meaning that the 5 point stencil might need information from another strip.
• local_matlab.png, an image that suggests the system of local workers available on a desktop machine.
• map.png, an image of an intercity highway system, with distances.
• md.png, an image that suggests the molecular dynamics simulation computation.
• md_profile.pdf, the performance report returned by MATLAB's profile command for the MD program.
• md_speedup.png, a plot of the speedup in execution time for a parallel version of the MD program.
• ode_maximum.png, an image that suggests how the ODE parameters define a solution, which in turn achieves a maximum value we want to track.
• ode_sweep_parfor.png, an image of a plot of the maximum solution values over a range of two parameters.
• parallel_matlab.png, an image that suggests the system of local and remote workers available to a user via the Distributed Compute Server.
• prime.m, a MATLAB function to count the number of primes less than or equal to N.
• prime.png, an image that suggests the prime number sieve.
• prime_script.m, a version of the prime number function rewritten as a script.
• quad.png, an image that suggests the quadrature problem.
• quad_fun_SPMD.m, a MATLAB function to estimate an integral using SPMD.
• spring_mass.png, an image of a spring-mass system.
• step000.png, the initial data for the heat equation.
• step010.png, the data for the heat equation after 10 steps.
• step020.png, the data for the heat equation after 20 steps.
• step040.png, the data for the heat equation after 40 steps.
• step080.png, the data for the heat equation after 80 steps.
• surfsup.m, a MATLAB function to filter the surfsup image.
• surfsup.png, an image to be filtered.
• surfsup2_summary.png, compares filtering on the client and in parallel, after messages were used.
• surfsup_filters_spmd.png, an image filtered in parallel, but without messaging.
• surfsup_summary.png, compares filtering on the client and in parallel, with no messages allowed between parallel workers.
• trapezoid_rule.png, an image that suggests the trapezoid rule approach to quadrature.
