Pdl Viewer

Pipe Viewer is a terminal-based tool for monitoring the progress of data through a pipeline. It can be inserted into any normal pipeline between two processes to give a visual indication of data transfer speed, ETA, that sort of thing.

PDL::Parallel::MPI Perl module contains routines to allow PDL objects to be moved around on parallel systems using the MPI library. SYNOPSIS use PDL; use PDL::Parallel::MPI; mpirun(2); MPI_Init(); $rank = get_rank(); $a=$rank * ones(2); print "my rank is $rank and $a is $an";...

frob 3D viewer project is a 3D object point/wireframe/polygon viewer - called frob3dv for lack of a better name. I wrote this version mainly to learn c++. Also it was the first program I wrote after I got a PC (and put linux on it), but it has a long history. Many years ago I wrote a few stacks...
