Free parallels workstation software for linux

QCad is an application for computer aided drafting in two dimensions. With QCad you can create technical drawings such as plans for buildings, interiors or mechanical parts. QCad works under Linux, Unix Systems, Mac OS X and Windows. The source code of QCad is released under the GPL (Open Source).
QCad was designed with modularity, extensibility and portability in mind. But what people notice most often about QCad is its intuitive user interface. QCad is a simple 2D CAD system for everyone. You dont need any CAD experience to get started with QCad immediately.
Main features:
- Various modes for creating lines, arcs, circles, ellipses, parallels, angle bisectors, ...
- DXF Format (DXF 2004, R12)
- Texts in many different CAD fonts
- Dimensioning of distances, angles, diameters, tolerances, ...
- Hatches and solid fills
- Splines
- Full support of Layers and Blocks (Inserts)
- Powerful selection and modification tools (move, rotate, mirror, trim, stretch, ...)
- Snapping to objects (endpoints, centers, intersections, ...)
- Console for co-ordinate positioning and launching commands
- Multiple undo / redo levels
- Support for various units including metric, imperial, degrees, grad, rad, ...
- Import and Export of Bitmaps (JPEG, PNG, ...)
- Creation of PS files which can be easily converted to PDF
- Translations of the user interface: Czech, Danish, Dutch, English, Estonian, French, German, Greek, Hungarian, Italian, Polish, Russian, Slovak, Spanish, Turkish
- Scripting interface
Enhancements:
- This update features improved DXF compatibility, improved support for ellipses, and some fixes for OS X.

Parallel::Workers::Shared is a simple Perl module.

Parallel::Workers::Shared requires no configuration files or environment variables.

GWCC allows users to execute network utilities (ping, nslookup, traceroute) and workstation commands (netstat, df, process grep) from a single tabbed window.
Welcome to GWCC.This program is designed to provide an easy to use interface to your Unix system. I dont know about you, but perform the same operations over-and-over day-after-day, and the command line provided via a terminal window ceases to be very useful once you want to start doing something with the information - like saving or printing it.
In addition to having to know all the flags for all the commands you want to use, you also have to scroll up-and-down the terminal window to retrace your steps and to cut-and-paste (what was that IP address again?).
So, i hope you will find my GTK/GNOME-based point-and-click application of some use in your daily computing activities. Please feel free to write to me with any suggestions you may have (see Contacting The Author below).
Main features:
- Complete preferences system (no need to edit any config files, or know flags)
- GNOME support (session management, dialogs, menus, etc.)
- LibGLADE support
- Saving and Printing of all output!
- Highly configurable command flags and program behaviour.

Parallel::Pvm is a Perl extension for the Parallel Virtual Machine (PVM) Message Passing System.

SYNOPSIS

use Parallel::Pvm;

The PVM message passing system enables a programmer to configure a group of (possibly heterogenous) computers connected by a network into a parallel virtual machine. The system was developed by the University of Tennessee, Oak Ridge National Laboratory and Emory University.

Using PVM, applications can be developed which spawns parallel processes onto nodes in the virtual machine to perform specific tasks. These parallel tasks can also periodically exchange information using a set of message passing functions developed for the system.

PVM applications have mostly been developed in the scientific and engineering fields. However applications for real-time and client/server systems can also be developed. PVM simply provides a convenient way for managing parallel tasks and communications without need for rexec or socket level programming.

As a utility, PVM enables an organisation to leverage on the computers already available for parallel processing. Parallel applications can be started during non-peak hours to utilise idle CPU cycles. Or dedicated workstation clusters connected via a high performance network like ATM can be used for high performance computing.

It is recommended that you read the PVM manual pages and the book "PVM: Parallel Virtual Machine, A userss guide and tutorial for networked parallel computing". Both the PVM system and the book can be obtained from the HTTP address http://www.epm.ornl.gov/pvm.

For the rest of this document we will provide a tutorial introduction to developing PVM applications using perl. The interface for some of the PVM functions have been changed of course to give it a more perl-like feel.
Remember think perl think parallel! Good Luck!

kparalleleport is a program for programmers who wish to use the parallel port.

The project makes it possible to view the values registered or read on the parallel port.

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";
$a->move( 1 => 0);
print "my rank is $rank and $a is $an";
MPI_Finalize();

MPI STANDARD CALLS

Most of the functions from the MPI standard may be used from this module on regular perl data. This is functionallity inherited from the Parallel::MPI module. Read the documentation for Parallel::MPI to see how to use.

One may mix mpi calls on perl built-in-datatypes and mpi calls on piddles.

use PDL;
use PDL::Parallel::MPI;
mpirun(2);

MPI_Init();
$rank = get_rank();
$pi = 3.1;
if ($rank == 0) {
MPI_Send($pi,1,MPI_DOUBLE,1,0,MPI_COMM_WORLD);
} else {
$message = zeroes(1);
$message->receive(0);
print "pi is $messagen";
}
MPI_Finalize();

Frocor stands for F Resonating Objects Correlator and is a sound- graphics installation.
Changes of properties of a Frocor object will result in changes of both the graphics and the sound output.
Main features:
It is based on some parallels between sounds and geometric objects:
Geometry
- Shape (Circle / Triangle / ...)
- Size
- Color
- Animation (Spinning)
Acoustics
- Sound Shape (Sine / Triangular / ...)
- Volume
- Frequency
- Sweep
Enhancements:
- 10/05/2005: first public frocor release: 0.1!

Parallel::ForkManager is a simple parallel processing fork manager.

SYNOPSIS

use Parallel::ForkManager;

$pm = new Parallel::ForkManager($MAX_PROCESSES);

foreach $data (@all_data) {
# Forks and returns the pid for the child:
my $pid = $pm->start and next;

... do some work with $data in the child process ...

$pm->finish; # Terminates the child process
}

This module is intended for use in operations that can be done in parallel where the number of processes to be forked off should be limited. Typical use is a downloader which will be retrieving hundreds/thousands of files.
