The Open CORBA Benchmarking Suite measures several basic performance aspects of various CORBA brokers.
The suite produces an XML output that can be submitted to a searchable database of broker performance data and browsed in a graphical form. The suite is portable to a number of platforms and brokers.
For C++ brokers
Enter the "C++" directory. Then enter the subdirectory of that directory that corresponds to the broker of your choice. Check the README file there for further instructions, usually you will use "make" to compile the benchmark.
For Java brokers
Enter the "Java" and then the "build" directory. Then enter the subdirectory of that directory that corresponds to the broker of your choice. Check the README file there for further instructions, usually you will use "ant" to compile the benchmark "ant run" to execute the benchmark.
Understanding results
The results do not get printed until the benchmark is finished, which can take from 2 to 4 hours depending on the platform. The best way to view the results is to capture them to a file and view them graphically at http://nenya.ms.mff.cuni.cz/~bench.
Enhancements:
- Support for system information on Linux 2.6 kernels.
- Slight extensions to the documentation.
- Support for some recent brokers on Solaris (VisiBroker 6.0, omniORB 4.0.5, JacORB 2.2.1).
- Support for some recent brokers on Linux (omniORB 4.0.5, JacORB 2.2.1, JDK 1.5.0, TAO 1.4.3).

Open BEAGLE is a C++ Evolutionary Computation (EC) framework. It provides an high-level software environment to do any kind of EC, with support for tree-based genetic programming, bit string and real-valued genetic algorithms, and evolution strategy.
The Open BEAGLE architecture follows strong principles of object oriented programming, where abstractions are represented by loosely coupled objects and where it is common and easy to reuse code.
Open BEAGLE is designed to provide an EC environment that is generic, user friendly, portable, efficient, robust, elegant and free.
With Open BEAGLE, the user can execute any kind of EC, as far as it fulfills some minimum requirements. The only necessary condition is to have a population of individuals to which a sequence of evolving operations is iteratively applied.
So far, Open BEAGLE supports most mainstream EC flavors such genetic programming, bit string and real-values genetic algorithms, and evolution strategy. It also includes support for advanced EC techniques such multiobjective optimization and co-evolution.
The user can take any of these specialized frameworks and modify them further to create his own specialized flavor of evolutionary algorithms.
Main features:
User Friendliness
- Considerable efforts were deployed to make the use of Open BEAGLE as easy and pleasant as possible. Open BEAGLE possesses several mechanisms that offer a user friendly programming interface. For example, the memory management of dynamically allocated objects is greatly simplified by the use of reference counting and automatic garbage collection. The programming style promoted is high-level and allows rapid prototyping of applications.
Portability
- The Open BEAGLE code is compliant with the C++ ANSI/ISO 3 standard. It requires the Standard Template Library (STL). No specific call in the core libraries are made to the operating system nor to the hardware.
Efficiency
- To insure efficient execution, particular attention was given to optimization of critical code sections. Detailed execution profiles of these sections were done. Also, the fact that Open BEAGLE is written in C++ contributes to its overall good performance.
Robustness
- Many verification and validation statements are embedded into the code to ensure correct operation and to inform the user when there is a problem. Robust mechanisms for periodically saving the current evolution state have also been implemented in order to enable automatic restart of interrupted evolutions.
Elegance
- The interface of Open BEAGLE was developed with care. Great energy was invested in designing a coherent software package that follows good OO and generic programming principles. Moreover, strict programming rules were enforced to make the C++ code easy to read, understand and, eventually, modify. The use of XML as file format is also a central aspect of Open BEAGLE, which provide a common ground for tools development to analyze and generate files, and to integrate the framework with other systems.
Free Sourceness
- The source code of Open BEAGLE is free, available under the GNU Lesser General Public License (LGPL). Thus, it can be distributed and modified without any fee. (See section copyright for further details.
Enhancements:
- Several fixes to allow compilation on Mac OS X
- Fixes in headers inclusion to allow precompiled headers

Open Proxy Scanning Bot (formerly NeoBOPM) is a loadable module for the NeoStats IRC Services. Open Proxy Scanning Bot scans clients connecting to the IRC network for insecure proxies, and also looks up a DNS blacklist for previously registered insecure proxies.
It caches the results of scans to increase perfomance, and with multiple bots, can be configured for load balancing.
It currently supports Hybrid7, Unrealircd, LiquidIRCd, Bahamut, QuantumIRCd, MysticIRCd, NeoIRCd, and Ultimate, with support for other ircds planned.
Enhancements:
- The code was updated to support NeoStats 3.0 Alpha 3.
- The DNS blacklist code was split out to a new module, BLSB.
- Several issues regarding NeoStats consuming 100% CPU when using OPSB have also been corrected.
- gcc 4.0 support was fixed.

Open Project Services (OPS) is a project collaboration platform, integrating server components such as e-mail, calendaring, timesheets, documents, knowledge, etc. with standards complient clients. Open Project Services consists of a project server and a set of client extensions.
We are building a project collaboration platform. It consists of a project server that integrates with services needed within a project, e.g. e-mail, calendaring, timesheets, documents, knowledge, etc.
The project server is a Webservices hub based on Java (J2EE). The persistence layer for project information is LDAP. We use OpenLDAP now, but others should also be possible. The e-mail backend makes use of a standard IMAP server. Our reference implementation uses Courier.
We are building extensions/plugins for clients, making them OPS-enabled. We support e.g. Mozilla Thunderbird (XUL) and Squirrelmail (PHP) for e-mail clients. For the calendaring and timesheet components we have a Mozilla Sunbird extension (XUL).
In short: we are building a project collaboration environment on an OSS stack, enriching services with project information, using COTS clients/servers and open standards.
Enhancements:
- This release includes some changes to the underlying LDAP schema to make it possible to disable tasks when they are completed.
- To make use of this new feature, the Web services and the sunbird timesheet client have to be updated.
