The following files were used:

• blast_speedup1.png, a plot of the speedup of the BLAST program for a single sequence.
• blast_speedup5.png, a plot of the speedup of the BLAST program for sequences of increasing size.
• clockspeeds.png, a plot of computer clockspeeds, showing the "ceiling" at 4 GigaHertz reached around 2003.
• fsu_logo.pdf, a logo.
• gpu_memory.png, a diagram of the layout of memory in a Graphical Processor Unit (GPU).
• gpu_speed.png, a chart showing the increase in computational rate for Graphical Processor Units (GPU's).
• lightcone.png, a diagram of a lightcone, a concept from physics showing how an event divides spacetime into the past (things that MUST have already happened), space (things that may be going on simultaneously) and the future (things that this event can affect). An analogous situation governs the data used in a numerical computation.
• linpack_mflops.png, a chart showing the computational speed for the Linpack benchmark over a range of problem sizes.
• mandelbrot_part.f90, part of a FORTRAN90 program to compute the Mandelbrot set.
• mandelbrot.png, an image of the Mandelbrot set.
• mflops2.png, a chart showing the speedup when using two processors.
• mflops4.png, a chart showing the time required for a task, over a range of problem sizes.
• parallel_matlab.png, an image suggesting the operation of parallel MATLAB.
• predator_prey.png, a plot of predator and prey populations, as computed by a simple finite difference model.
• predator_prey_part.m, part of a MATLAB program for the predator-prey problem.
• protein.png, an image of a protein. A sequence alignment treats a protein as a string of symbols. A pairwise alignment considers all the possible ways of matching successive symbols in two such strings.
• quad_core.png, a diagram of the arrangement of cores and memory in a quad core processor.
• riemann_sum.png, a plot of the Riemann sum method of estimating an integral.
• riemann_sum_part.f90, part of a FORTRAN90 program for the Riemann sum.
• server_rack.png, a rack of servers, a typical way of stacking stripped down computers in a cluster.
• tasks_beerli.png, a plot of the logical dependence of tasks in Peter Beerli's MIGRATE calculations.
• tasks_gauss.png, a plot of the logical dependence of tasks in Gauss elimination.
• tasks_parallel.png, a plot of how a set of sequential tasks might actually be logically arranged.
• tasks_sequential.png, a plot of how a sequential computer sees a series of tasks.
• time_ratio.png, a ratio of two execution times.
