Parallel Network Scanner 1.11

Parallel Network Scanner 1.11


Parallel Network Scanner provides a fast network services scanner. more>>
Parallel Network Scanner provides a fast network services scanner.
pnscan is a scanner for TCP network services. It uses multithreading to increase its speed.
pnscan tries to be smart as to how many threads to start - it will dynamically start only as many as is needed to make progress in the scan - up to a maximum either as specified with the "-n" command line option, or 8 minus the maximum number of available file descriptors (pnscan tries to increase
it to the max limit automatically) - or any internal limit on the system (Linux normally only allows 256 threads).
Host ranges can be specified both as a CIDR - network name or IP address / mask bit length and as a range. When using CIDR notation - the first and last address is ignored (normally used for broadcasts)
Some examples:
192.168.0.0/24
192.160.0.1:192.160.0.254
arpanet/8
USAGE - EXAMPLES
# Scan network 192.168.0.0/24 for SSH daemons on port 22
pnscan 192.168.0.0/24 22
pnscan 192.168.0.1:192.168.0.254 ssh
# Scan hosts 192.168.10.34 ... 98 for IDENT servers, max 8 threads
pnscan -n8 -w"VERSION" 192.168.10.34:192.168.10.98 113
# Scan host 127.0.0.1 for WWW servers on all ports
pnscan -w"HEAD / HTTP/1.0rnrn" -r"Server:" 192.168.0.32 1:65525
pnscan -w"HEAD / HTTP/1.0rnrn" -r"Server:" localhost 1:65525
# Send binary data and expect the binary sequence FF 00 FF on port 145.
pnscan -W"05 5A 37" -R"FF 00 FF" 192.168.0.32 145
# Scan for Roxen servers and print the whole Server-line
pnscan -l -w"HEAD / HTTP/1.0rnrn" -r"Roxen" localhost 1:65525
# Scan for pidentd servers and try to locate the version
pnscan -w"VERSION" 192.160.0.0/24 113
# Scan network arpanet/24 for daytime servers and sort them IP-numerically
pnscan arpanet/10 daytime | ipsort
# Read host (&port) lines from stdin and scan the selected hosts for SSH
echo 192.160.10.11 ssh | pnscan -v
echo 192.160.10.12 | pnscan 22
Enhancements:
- pnscan.sgml Added the other options implemented in pnscan.c.
- pnscan.c: Modified the threads startup code to dynamically only start as many threads as is needed.

Parallel Bladeenc 0.92.1b5

Parallel Bladeenc 0.92.1b5


Parallel Bladeenc is a true parallel version of the Bladeenc MP3 encoder. more>>
Parallel Bladeenc is a true parallel version of the Bladeenc MP3 encoder; it distributes work across CPUs to speed up MP3 encoding. It uses the Message Passing Interface (MPI) for parallelization across SMPs and/or multiple machines. Hence, if you have a 4-way SMP, you can encode your MP3s about 4 times as fast as the regular Bladeenc; if you have two 4-way SMPs, you can encode about 8 times as fast.
The difficult part about parallelization is typically about how to split the problem up into independent (or nearly independent) parts. The structure shown above - assuming that the encode() function was independent of previous calls to encode() - is trivial to parallelize.
For example, if we want to run on four machines, we can split the input file into four parts, give 1/4 of the file to each machine, and let each machine loop over encode() for their portion of the file. Then take the output from each machine, put it in the right order, and write it out to a single output file. Done.
With such a scheme, the more work that you throw at it, the more efficient it will become.
Hence, trying this scheme with small MP3 files will probably not result in any noticeable speedup (in fact, it may be slower than running in serial, because of the added overhead for working in parallel). It is necessary to give the parallel engine enough work to offset the overhead added by the parallel framework. Generally, this is not very much overhead (read on to find out why), but parallel is not free.
Enhancements:
- Fixed minor error that caused an error message from MPICH when shutting down. Thanks to Gary Smith for pointing this out.

CarWorld is a small driving simulator/demo I use to test various things of interest. It was mostly developed when I was a student. Car World is released with the full source code under the GNU General Public License.

The rendering

The two top pictures represent an slightly older version (v0.072) but graphically similar of CarWorld as it was presented for my project. v0.072 includes an OpenGL based renderer allowing
file input and displaying of texture mapped models with interpolated surface normals, real time projected shadows (as seen in the dino lights example).
background object
on screen command line to modify visual and simulation parameters

The mechanics

based on classical mechanics
uses standard metrics (Newtons, meters, seconds...)
there are no constraints on the environment surface
variable length time increments and variable increment number means "CarWorld time" is not dependent on frame rate.
adjustable simulation specs include: metrics, mass, moment of inertia around rotation axis, suspension pre load, compression damping, rebound damping, engine torque output, air friction, surface friction.

Parallel::Pvm 1.4.0

Parallel::Pvm 1.4.0


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

Tile World 1.2.2

Tile World 1.2.2


Tile World is an emulator of Chips Challenge. more>>
Tile World is an emulation of the game "Chips Challenge". "Chips Challenge" was originally written for the Atari Lynx by Chuck Sommerville, and was later ported to MS Windows by Microsoft (among other ports).

Please note: Tile World is an emulation of the game engine(s) only. It does not come with the chips.dat file that contains the original level set. This file is copyrighted and cannot be freely distributed. The chips.dat file was originally part of the MS version of "Chips Challenge". If you have a copy of this version of the game, you can use that file to play the game in Tile World. If you do not have a copy of this file, however, you can still play Tile World with the many freely available level sets created by fans of the original game, including CCLP2.

"Chips Challenge" is a game made up of both intellectually engaging puzzles and situations demanding fast reflexes. As you might have guessed, it is a tile-based game. The object of each level is simply to get out -- i.e., to find and achieve the exit tile. This simple task, however, can sometimes be extremely challenging.

Hell World 0.1.5


Hell World is a thrilling FPS adventure game which features excellent graphics. more>>
Hell World is a thrilling FPS adventure game which features excellent graphics, a dark atmosphere and an excellent scenario. Hell World game is designed to be a port of the Windows-only version of Hell World.
It is written using the openGL and SDL library and is developing for the last months by ironhell3.
The game starts from main.c There we call first two functions, sdl_init() and game_init() to initialise the sdl and game part of the game.After the succesfull initialisation of Hell World we loop in a while() function.Each frame we check the keyboard and mouse for events through keyhandler() and then render the game frames through loop().When we catch a done=true signal we quit the game.
Important:
1)We are in need of developers,musicians,artists etc to help develop this game
2)This game is released under the GPL license.Please READ the COPYING file for more info
Enhancements:
- Fixed movement
- Added fog
- Added crates
- Redesign of level 1 including texture changes

Parallel::Queue 1.00

Parallel::Queue 1.00


Parallel::Queue is a Perl module to fork or thread a list of closures N-way parallel. more>>
Parallel::Queue is a Perl module to fork or thread a list of closures N-way parallel.

SYNOPSIS

# example queue:
# only squish files larger than 8KB in size. figure
# that the system can handle four copies of squish
# running at the same time without them interfering
# with one another.

my @queue = map { -s > 8192 ? sub{ squish $_ } : () } @filz;

# functional: pass in the count and list of coderefs.
#
# adding runqueue exports the subroutine into
# the current package. useful for non-OO situations.
#
# run the queue 4 way parallel.

use Parallel::Queue qw( runqueue verbose fork );

my @remaining = runqueue 4, @queue;

die "Incomplete jobs" if @remaining;

# OO: generate queue manager and use without the
# runqueue arguments, construct a queue manager,
# and use it to run the jobs

use Parallel::Queue;

my $quemgr = Parallel::Queue->construct( thread );

$quemgr->runqueue( 4, @queue );

die "Incomplete jobs" if @queue;

# call Parallel::Queue with the default configuration
# (fork quietly).

require Parallel::Queue;

Parallel::Queue->runqueue( 4, @queue );

# pre-define defaults for the objects: leave
# out runqueue, set the rest, and construct
# an object. the one here gets verbose, thread,
# and debug all set to true.

use Parallel::Queue qw( verbose thread );

my $quemgr = Parallel::Queue->construct( debug );

my @remaining = $quemgr->runqueue( 4, @queue );

Given a count and an array of coderefs (most likely closures), runqueue will run the jobs in parallel. The jobs can be run via fork or detached threads [see known issues for threading]. Jobs on the queue are executed until one of them exits non-zero, the fork/thread operation fails, or all of them are dispatched (i.e., the queue is empty).
