Multiprocessor Computation

Computation Job Management (jobman in short) is a program that calls executables according to a given program flow. Each executable is run in a separate process. It is useful when a project needs to carry out a series of calculations that are performed by software written in different languages...

Tachyon is a multiprocessor ray tracing system which can be used as a standalone program, or as a library within other programs. The project is written in C, uses POSIX Threads and/or MPI for using multiple processors, and can also run on uniprocessor machines. It supports almost any Unix-like...

CARDboard Illustrative Aid to Computation, or Cardiac, for short was designed as a learning aid in order to teach high school students how computers work. The kit consisted of an instruction manual and a die-cut cardboard "computer". The computer "operated" by means of pencil and sliding...

Interactive Evolutionary Computation (IEC) can handle such optimization problems where the objectives are non-commensurable or explicitly/mathematically not available.IEC is a technique from the class of evolutionary algorithms (EAs), whose fitness function is replaced by a human. The human user...

This example is a proof-of-concept to show that handle objects can be used to model dependencies between different steps of a set of computations. It shows that objects can be used to hide the complexity of arranging the order of computations that partially depend on each other. The computation...

Occasionally I see a request for computation of a running, windowed standard deviation. This is easily accomplished using filter and the alternative formula for the standard deviation:std = sqrt((sum(x.^2) - n*xbar.^2)/(n-1)).Movingstd allows you to specify forward, backward or central windows of...
