Paderborn University BSP Library 01-26-2007
Paderborn University BSP Library is a C-Library to support development of parallel algorithm. more>>
Paderborn University BSP Library is a C-Library to support development of parallel algorithm based on the "Bulk-Synchronous-Parallel-Model".
The Library offers buffered asynchronous message-passing between the nodes, organized in supersteps. At the begin of a superstep the nodes receive all messages which has been sent in the previous superstep.
The PUB-Library supports in addition to send node-to-node messages other functions like broadcasts and parallel prefix operations with a set of nodes.
PUB offers functions for both message passing and remote memory access. Furthermore, some collective communication operations like broadcast and parallel prefix are also provided.
To become more flexible, PUB allows creating independent BSP objects each representing a virtual BSP computer. Goudreau et al.[GHL$^+$96] defined an interface for BSP libraries call ``BSP Worldwide Standard which is implemented in the Oxford BSP toolset[HDM97]. You can also use the BSP Worldwide Standard for programming with PUB (refer to Section 1.6).
A performance comparison with other communication libraries and some implementation details can be found in [BJOR99].
The PUB-Library is available for several parallel platforms. The generated library is specified by four configuration variables PUB_MACHINE (machine type), PUB_SYSTEM (operating system), PUB_COMMUNICATION (communication library) and PUB_MODE (e.g. debug).
Enhancements:
- This release adds numerous minor bugfixes.

Boston University Linux 4.5 Server Edition (Zodiac)
Boston University Linux is based on Fedora Core Linux, but specifically tailored for the BU environment. more>>
Boston University Linux is based on Fedora Core Linux, but specifically tailored for the BU environment.
Weve added security updates, made modifications to make software work better with the way things are set up here, and added some applications that we think you might like to have.
The server edition of BU Linux provides a modern, stable, and robust server platform suitable for long-term deployment in many roles throughout the university.
Supported Hardware
Currently, only i686-class machines are supported. This includes almost everything from Intels Pentium Pro on. AMD64 and Intel EM64T systems will work fine using their 32-bit mode. Watch for a 64-bit version later this summer.
Specific Notes on Server Applications
Mail Server:
BU Linux 4.5 Server Edition (Zodiac) includes three different choices of Mail Transfer Agent (MTA) for your mail server. Each of these open source servers has its unique strengths, and you can install one or more and use the utility system-switch-mail to choose which is active.
The default is IBMs Postfix, which is designed from scratch to be secure and easily configurable. On a newly-installed BU Linux machine, Postfix is configured to exchange mail on the local machine and to send mail out to other systems, but not receive mail from the network. For this reason, outgoing mail from global BU accounts (those matching valid BU login names and with the proper UID) will appear to come from @bu.edu rather than @hostname.bu.edu. Local users (including system accounts) will retain the hostname, but without reconfiguration, any replies will bounce. Changing the system to accept mail is easy; see the BU Linux web site for details.
For the maximum flexibility and for compatibility with existing configurations (and with existing expertise), we also include the traditional standard Sendmail. And, if you have particular special needs, you may find that the new Exim MTA fits your situation best.
No matter which MTA you choose, please contact us if you need any assistance. With so many options available, the situation can be confusing, and its unfortunately easy for an accidentally misconfigured system to become a target for spam relayers. We have significant expertise at configuring both Postfix and Sendmail in a variety of situations, and will be glad to help.
FTP Server:
This release of BU Linux provides two options for FTP. The first is vsftpd, which is designed to be simple and secure. This is the most appropriate for almost all situations, but if you require more power and flexibility, we also include ProFTPd, which has many more options and a configuration syntax similar to that of the Apache web server.
Please also remember that FTP is an insecure protocol and that any passwords used travel over the network in plain text. For this reason, its best to avoid anything but anonymous FTP. For user-authenticated file transfer, use SSH and SFTP. (SFTP is provided by the OpenSSH server and enabled by default.)
Web Server:
The web server software included in BU Linux is the industry-standard Apache httpd. We also include PHP 4.3 and many other useful tools for building a web server.
If you need to provide authenticated access to web services to BU users, please contact us and we will provide you with our University-standard Weblogin module. This provides a powerful and flexible means of single-signon access control for the BU user community and we want to make it as easy as possible for you to provide this for your users.
Database Server:
BU Linux includes MySQL 4.1 and PostgreSQL 7.4. For less demanding SQL applications, we also provide SQLite 3, which provides simple SQL databases without the management overhead of running a SQL server.

MWSpeaker 1.0
MWSpeaker project is the worst speech synthesis software ever. more>>
MWSpeaker project is the worst speech synthesis software ever.
You provide a phrase, and MWSpeaker looks up each word in Merriam-Websters online dictionary, downloads the corresponding pronounciations, and plays them in sequence.
M-W Speaker takes a phrase (no punctuation please), takes each work, looks it up on the Meriam Webster website, downloads the sound file, and then, once it has sound files for each word in the phrase, plays them all back to back.
The result is something that resembles the sentence with any proper names and words not considered proper english words removed. This process is pretty slow since each word has to be looked up and the sound file downloaded by hey :)
This is mostly just for fun. I see no practical use for this whatsoever.
Its written in Python.

PostgreSQL 8.2.4
PostgreSQL is The Worlds Most Advanced Open Source Database. more>>
PostgreSQL is a highly-scalable, SQL compliant, open source object-relational database management system. With more than 15 years of development history, it is quickly becoming the de facto database for enterprise level open source solutions.
PostgreSQL is an object-relational database management system (ORDBMS) based on POSTGRES, Version 4.2, developed at the University of California at Berkeley Computer Science Department. POSTGRES pioneered many concepts that only became available in some commercial database systems much later.
PostgreSQL is an open-source descendant of this original Berkeley code. PostgreSQL supports SQL92 and SQL99.
Main features:
- complex queries
- foreign keys
- triggers
- views
- transactional integrity
- multiversion concurrency control
Additionally, PostgreSQL can be extended by the user in many ways, for example by adding new:
- data types
- functions
- operators
- aggregate functions
- index methods
- procedural languages
And because of the liberal license, PostgreSQL can be used, modified, and distributed by everyone free of charge for any purpose, be it private, commercial, or academic.

mod_ometer 1.3.0
mod_ometer is a web counter implemented as an apache C module. more>>
mod_ometer is a web counter implemented as an apache C module. mod_ometer Apache module uses gd 2.0.28 or later to generate its images. Gd has some built-in fonts, but for real excitement you can use any TrueType font you want for the counter.
In addition to allowing font choice, mod_ometer has all sorts of options for customizing size, width and color of your counter as well as the ability to output the counter as jpeg, png, or gif.
Main features:
- ignore: ip address or domain name is forbidden to increment the counter.
- font: use a truetype font instead of the counters default.
- width: how many digits are displayed, maximum of 10.
- rand: display a different random number everytime.
- reset: reset the counter to a specific value.
- text: set font color using the "web color" scheme.
- bgcolor: set background color using the "web color" scheme.
- point: set point size of the counter font.
- image: choose jpeg, png or gif.

Attendance sheet is a simple script that will help you keep track of registrations for arbitrary sports activities that take place regularly.
The idea came from the problem our small group of amateur volleyball at our University faced. At the beginning the number of players was quite small and since many times we did not know each other well, we often ended up coming in 2 or 3 people.
Attendance-sheet helps to:
- see registered players who is coming and who is not
- make registered players to know each other better (if they are from different faculty or whatever), supported by photo, fullname, icq # and faculty

The Program Database Toolkit 3.10
The Program Database Toolkit is a powerful tool infrastructure that provides access to the high-level interface of source code. more>>
The Program Database Toolkit (PDT) is a powerful tool infrastructure that provides access to the high-level interface of source code for analysis tools and applications.
Many tasks in an integrated programming environment require access to program information for their implementation. Program Database Toolkit (PDT) is a framework for analyzing source code written in several programming languages and for making rich program knowledge accessible to developers of static and dynamic analysis tools.
PDT implements a standard program representation, the program database (PDB), that can be accessed in a uniform way through a class library supporting common PDB operations. Software tools can use this library to accomplish tasks such as
- documentation of program components
- creation of graphic program browsers that show class hierarchies, function call graphs, and template instantiations
- insertion of instrumentation for performance profiling and tracing; andgeneration of interface details for calling library routines or buildinginterlanguage bindings.
Enhancements:
- Assorted minor bugfixes.

$status = _GFlush();
$status = _GLine( @x, @y );
$status = _GMark( @x, @y, $type );
$status = _GText( $text, $x, $y, $just, $upx, $upy );
( $status, $xb, $yb ) = _GTxExt( $text, $x, $y, $just, $upx, $upy );
( $status, $chv, $chh ) = _GQch();
( $status, $old_value ) = _GAttr( $attr, $value, $prim );
( $status, $alpha, $beta) = _GScales();
This file implements the low level graphics functions required by the rest of AST, by calling suitable PGPLOT functions (the FORTRAN PGPLOT interface is used).
This file can be used as a template for the development of similar modules to support alternative graphics systems.
