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

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

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.

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.

Parallel::Workers::Backend - The backend is a plugins mechanism to run the worker tasks. Default plugins are implemented for Eval (CODE), SSH and XMLRPC tasks. You can add your own plugin with module name Parallel::Backend::YourTaskModule

SYNOPSIS

use Parallel::Workers::Backend;

my $worker=Parallel::Workers->new(backend=>"Eval");
my $worker=Parallel::Workers->new(backend=>"SSH");
my $worker=Parallel::Workers->new(backend=>"XMLRPC");
my $worker=Parallel::Workers->new(backend=>"YourTaskModule");

Parallel MPI BZIP2 is a parallel implementation of the bzip2 block-sorting file compressor that uses MPI and achieves significant speedup on cluster machines.

The output of this version is fully compatible with bzip2 v1.0.2 or newer (ie: anything compressed with mpibzip2 can be decompressed with bzip2). MPIBZIP2 should work on any system that has a pthreads compatible C++ compiler (such as gcc). It has been tested on: Linux and Solaris.

NOTE: If you are looking for a parallel BZIP2 that works on multi-processor/muti-core/SMP machines, you should check out PBZIP2 which was designed for a multi-threaded shared-memory architecture.

Usage:

Run mpibzip2 for the help listing.
==================================================================
Usage: mpibzip2 [-1 .. -9] [-b#cdfktvV] < filename > < filename2 > < filenameN >

-b#: where # is the file block size in 100k (default 9 = 900k)
-c : output to standard out (stdout)
-d : decompress file
-f : force, overwrite existing output file
-k : keep input file, dont delete
-t : test compressed file integrity
-v : verbose mode
-V : display version info for mpibzip2 then exit
-1 .. -9 : set BWT block size to 100k .. 900k (default 900k)

Example: mpibzip2 -b15k myfile.tar
Example: mpibzip2 -v -5 myfile.tar second*.txt
Example: mpibzip2 -d myfile.tar.bz2

F-Prot Antivirus security software package has various components that help keep your system secure from viruses, backdoors, trojans and other malicious programs. The project includes the RealTime Protector, a memory-resident monitoring utility that observes all files accessed on your system, a Scheduler where you can set the Scanner to make automatic scans or updates on your system at any time and an Updater to manage all signature updates.
For home users using the Linux open-source operating system, we offer F-Prot Antivirus for Linux Workstations. F-Prot Antivirus for Linux Workstations utilizes the renowned F-Prot Antivirus scanning engine for primary scan but has in addition to that a system of internal heuristics devised to search for unknown viruses
F-Prot Antivirus for Linux was especially developed to effectively eradicate viruses threatening workstations running Linux. It provides full protection against macro viruses and other forms of malicious software - including Trojans.
Main features:
- Scans for over 191534 known viruses and their variants
- Ability to perform scheduled scans when used with the cron utility
- Scans hard drives, CD-ROMS, diskettes, network drives, directories and specific files
- Scans for images of boot sector viruses, macro viruses and Trojan Horses
F-Prot Antivirus for Linux Workstations is FREE for use by personal users on personal workstations

3. Register yourself as a Black Orion Network Member

Register yourself as a member in the Black Orion Network section.

4. Install Black Orion on a computer

Read the manuals for the various installation options. The system can also be installed as a rhel4 virtual machine.

5. Connect your system to the Black Orion Network

Connect your system to the Black Orion Network with the up2date client installed on your system. You can find up2date by right-clicking the Black Orion Network Alert Icon on your desktop. Connect your system with your member name and password (see 3).

The goal of the Parallel Virtual File System (PVFS) Project is to explore the design, implementation, and uses of parallel I/O. PVFS serves as both a platform for parallel I/O research as well as a production file system for the cluster computing community. PVFS is currently targeted at clusters of workstations, or Beowulfs.
The PVFS project is conducted jointly between The Parallel Architecture Research Laboratory at Clemson University and The Mathematics and Computer Science Division at Argonne National Laboratory.
Additional funding for the PVFS project comes from NASA Goddard Space Flight Center Code 930 and The National Computational Science Alliance through the National Science Foundations Partnerships for Advanced Computational Infrastructure.
Main features:
- Compatibility with existing binaries
- Ease of installation
- User-controlled striping of files across nodes
- Multiple interfaces, including a MPI-IO interface via ROMIO
- Utilizes commodity network and storage hardware
PVFS supports the UNIX I/O interface and allows existing UNIX I/O programs to use PVFS files without recompiling. The familiar UNIX file tools (ls, cp, rm, etc.) will all operate on PVFS files and directories as well. This is accomplished via a Linux kernel module which is provided as a separate package.
PVFS is easy to install. The Quick Start page describes how to set up a simple installation. Scripts and test applications are included to help with configuration, testing for correct operation, and performance evaluation.
PVFS stripes file data across multiple disks in different nodes in a cluster. By spreading out file data in this manner, larger files can be created, potential bandwidth is increased, and network bottlenecks are minimized. A 64-bit interface is implemented as well, allowing large (more than 2GB) files to be created and accessed.
