The G System, often simply called "G", is an effort to create exactly this: simulation of evolution. This is both, a scientific exercise and a virtual reality where many "users" can participate in an ever changing, realistic and ... evolving universe.
G is basically a framework for virtual world simulations. And not only a framework (the "G System") but a virtual reality itself, which will become the application created with the G System.
- Multi-User 3D virtual world experience. The G System provides a 3D virtual reality that can be experienced by many users at the same time. The Users are part of the evolving universe.
- Simulation. The goal of G is to simulate a realistic, dynamic and evolving universe. To allow great flexibility a well designed core system provides the infrastructure for the world. The whole world is made up with elements.
Elements allow for creation of rule systems (like realistic physics, impact of feelings,...) to be applied to elements as well as integration of artificial intelligence (and anything else that is needed) to create evolutionary abilities.
Rule systems are created with "agents". These agents can reach arbitrary complexity and are executed as a thread, thus allowing maximum freedom to the agent design. Users can enter the world and interact with their environment, which ultimately has an impact on the evolution of the virtual universe. Thus, users make up a part of the overall simulation.
Enhancements:
LIBRARIES
G Core System (GCS):
- GCS::GObject does not store the IDs of the children anymore
- GCS::GWorldData can now return a list of children of an element
G World Engine (GWE):
- Bugs fixed concerning connecting to the G Universe
- Mutex deadlocks fixed that prevented the demo to run
- XMPP Presence subscriptions are now handled and in use
- Added new GStorage class wich implements a Qt based database layer, every database supported by Qt is supported by the G System, tested and known to work so far: QSQLITE, QMYSQL3, QPSQL7
- GStorage now used instead of GXmlStorage
- All GXmlNetwork related classes have been removed
- Fixed iterator bug that could cause crashes
- The factory has been adapted to the new database options
BINARIES
guniverseclient:
- Extracted the communication/chat area into a separate widget
- Now differentiates between internal and external contacts in the
- contact list.
- The default configuration file is now in $HOME/.guniverseclient.xml
- This makes it easy to have different configurations for every user

E-Cell System is a concept of constructing virtual cells on computers.
E-Cell System is an object-oriented software suite for modeling, simulation, and analysis of large scale complex systems such as biological cells, architected by Kouichi Takahashi and written by a wonderful team of developers. Core part of the system, E-Cell Simulation Environment version 3, allows many components driven by multiple algorithms with different timescales to coexist.
E-Cell Project is an international research project aiming at developing necessary theoretical supports, technologies and software platforms to allow precise whole cell simulation.
E-Cell System consists of the following three major parts:
- E-Cell Simulation Environment (or E-Cell SE)
- E-Cell Modeling Environment (or E-Cell ME)
- E-Cell Analysis Toolkit
Main features:
Basic capabilities
- Object-oriented modeling and simulation of complex systems.
- Plug-in architecture. New user-object classes can be developed, dynamically loaded, and used in simulation.
- Real-time user interaction and visualization during the simulation.
Scripting
- Python scripting of a simulation session (run/stop/parameter manipulation/data processing etc...).
- Python scripting of a simulation experiment that involves many runs of the simulation sessions (such as parameter tuning, metabolic control analysis etc..)
- Python scripting of model file generation (e.g. for automated model construction from databases).
Compatibilities
- SBML level 1/2 importing.
- SBML level 1/2 exporting.
Parallel computation
- Shared-memory, multi-thread parallelization of a single simulation session. (to be merged into the main branch.)
- Cluster and grid distributed computation of multiple simulation sessions. Sun Grid Engine, (Globus toolkit).
Enhancements:
- This release includes improved ODE/DAE solvers, support for numpy, an updated empy preprocessor, and some more minor improvements.

Yet Another Community System provides a community system including Web-based chat.

YaCS is a community system, written in C++. It is fully multi-threaded and uses heavy I/O multiplexing to get maximum performance and the lowest CPU load.

This system actually supports a chat system comparable to Cassiopeia (GiMiX) with some very useful features.

Nelisys project is Open Source Web-based Management System, to manage and monitor system and network including Router, Switch, Wi-Fi Access Point, Server, Networking services, etc.

There are performance and fault management function.

Remote Secure Command System project is a remote asynchronous and secure command system based on a file configuration.

A standalone server sends and receives commands through files, and a batch system launch ssh and scp commands.
