Equalizer is middleware for creating and deploying parallel OpenGL-based applications. It enables applications to benefit from multiple graphics cards, processors, and computers to scale rendering performance, visual quality, and display size. An Equalizer-based application runs unmodified on any visualization system, from a simple workstation to large scale graphics clusters, multi-GPU workstations, and Virtual Reality installations.
libGlass is a scalable set of components that can be used by applications to perform distributed computing. Applications are built by reusing the available components as needed. One of the major goals of Glass is to be a user-friendly framework, not only suitable for new applications, but also for legacy code. This is an important feature, as most available solutions for distributed computing require a substantial amount of rewrite of legacy code.
Channel is a C++ template framework for distributed message passing and event dispatching. Its major components (message IDs, routing algorithms...) are highly configurable as template parameters. As a namespace shared by peer threads, channels support publish/subscribe scope control, message filtering, and translation.
The IberAgents platform is a framework for component development in Java. It has facilities for Web service communication (SOAP), persistence to database or files, and interaction via the Web; thus providing an end-to-end solution for data management. It uses its own SOAP library, so it does not depend on Axis or Apache Soap.
