Free grid 1.2 software for linux

wxPropertyGrid is a property sheet control for wxWidgets.

wxPropertyGrid is a specialized two-column grid for editing properties such as strings, numbers, flagsets, string arrays, and colours.

GridMPI is a new open-source free-software implementation of the standard MPI (Message Passing Interface) library designed for the Grid. GridMPI project enables unmodified applications to run on cluster computers distributed across the Grid environment.
GridMPI team found that it is feasible to connect cluster computers and to run ordinary scientific applications in distance upto 500 miles. Simple experiment has shown that most MPI benchmarks scale fine upto 20 millisecond round-trip latency which corresponds to about 500 miles in distance, when the clusters are connected by fast 1 to 10 Gbps networks. 500 miles covers the major cities between Tokyo--Osaka in Japan.
Thus, applications which are too large to run on a local cluster should run on multiple clusters in the Grid environment with acceptable performance. However, it is only feasible when using an efficient MPI implementation [1]. Existing implementations are not efficient enough mainly because of the two reasons: their focus on security features and TCP performance problems.
GridMPI skips security layers assuming dedicated secure links. The institutes housing large clusters tend to have their own networks to connect to other institutes in most cases. GridMPI so focuses on the performance on TCP. Since existing implementations are in most cases designed for MPP machines and recently clusters with special hardware, their performance on TCP with Ethernet is not optimal.
Also TCP performance itself is not optimal for the work load of the MPI traffic. In addition, support for heterogeneous combinations of computers of the existing MPI implementations is not satisfactory. Thus, GridMPI is designed and implemented from the scratch. GridMPI is carefully coded and tested with heterogeneity in mind.
Main features:
- Full conformance to the standard: GridMPI passes 100% of the functional tests of the large test suites from ANL and Intel (MPI-1.2 level).
- Full heterogeneity support: GridMPI is fully tested with combinations of processors of 32bit/64bit and big/little-endian.
- Primary support of TCP/IP and sockets: GridMPI is written from scratch and it is new and clean. It is efficient with sockets, and thus suitable for the Grid as well as ordinary Ethernet-based clusters.
- Cooperation with Grid job submission: GridMPI can be used with Globus, Unicore, tool from NAREGI project, etc.
- Checkpointing support: GridMPI supports checkpointing on Linux/IA32 platforms to restart long-running applications from failure.
- Vendor MPI support: GridMPI supports IBM-MPI, Fujitsu-Solaris-MPI, Intel-MPI, and any MPICH-based MPI for clusters with special communication hardware.
Enhancements:
- Minor bugfixes were made.

Grid-Split plugin splits an image into several images.

You specify number of rows and columns and the files are saved to jpeg, gif or png.

Greed project is a strategy game.
Try to eat as much as possible of the board before munching yourself into a corner.
The object of Greed is to erase as much of the screen as possible by moving around in a grid of numbers. To move your cursor, simply use your arrow keys or the the hjklyubn keys or your numberic Your location is signified by the @ symbol.
When you move in a direction, you erase N number of grid squares in that direction, N being the first number in that direction. Your score reflects the total number of squares eaten.
Greed will not let you make a move that would have placed you off the grid or over a previously eaten square. If no valid moves exist, your game ends.
Other Greed commands are Ctrl-L to redraw the screen, p to toggle the highlighting of the possible moves, and q to quit.
The only ommand line option to Greed is -s to output the high score file.
Enhancements:
- better interrupt handling and the `p suffix to GREEDOPTS

Biniax is an unique arcade logic game. Simple and addictive, you can learn in a minute and play for hours.
The gaming field is a 5x7 grid filled partially with pairs of elements. Every pair consists of two different elements combined of four possible.
You control the box with an element inside and can move around the field on empty spaces. You can also remove pairs of elements if you have the same element as the one of the pair.
When you remove the pair, your element becomes the other one element of the pair and the score is increased. The gaming field scrolls down slowly and your goal is to stay on the field for as long as possible.
Enhancements:
- After months of playing, this release introduces the new time balance.
- This is an important change in the gameplay.

Grid::Transform is a Perl module with fast grid transformations.

SYNOPSIS

use Grid::Transform;

$g = Grid::Transform->new([a..o], rows=>5);
$g->rotate_270->flip_vertical;
print join( , $g->grid), "n";

The Grid::Transform module provides fast methods to transform a grid of arbitrary data types.

METHODS

$g = Grid::Transform->new( @grid, rows=>num, columns=>num )

Creates a new Grid::Transform object. The first argument is a reference to a 1-dimensional array representing a 2-dimensional "row major" (row by row) grid. (A column major grid is simply the counter transpose of a row major one.) The grid may be composed of arbitrary data types. The original array is never modified- all transformations operate on a copy.

At least one dimension must be specified. If the grid and dimensions do not produce a rectangular grid extra empty elements ("") will be added to the grid.

$g2 = $g->copy

Returns a copy of the original Grid::Transform object.

These methods get or set the grid attributes:

@grid = $g->grid
$grid = $g->grid
@grid = $g->grid( @grid )

In list context, returns an array representing the current grid. In scalar context, returns a reference to the array. Accepts an array reference representing a new grid. The new grid will be resized if the dimensions of the previous grid do not match.

$g->rows
$g->rows( $num )

Returns the current number of rows.

$g->columns
$g->cols
$g->columns( $num )

Returns the current number of columns.

All transform methods return the Grid::Transform object, so transforms can be chained.

$g->rotate_90

GRIDportal is a Web-based application portal that acts as a frontend to GRID computing. GRIDportals aim is to make common GRID applications like Abaqus, Matlab, or BLAST more accessible to the user.

Use of GRIDportal does not require any knowledge of Unix nor GRID computing whatsoever. All the user needs to know is how to use the given application, so the step from desktop computing to GRID computing should thus become a much smaller one than it otherwise would be.

GRIDportal, written in Python and based on Webware for Python, is meant to be modular, which allows quick development of plugins for new applications.

GRIDportal is built on top of NorduGrid/ARC middleware and depends on the middleware to function. This relationship between GRIDportal and NorduGrid/ARC also allows a user to access the entire NorduGrid network through GRIDportal (provided the user has the necessary credentials), thus making GRIDportal a gateway to a whole range of different GRID sites.

GRIDportal was born from Jonas Lindemanns LUNARC Application Portal and is distributed under the GPL licence.
