CGRU is an open source CG tools pack, includes Afanasy render farm manager.
Checkpoint/Restart functionality for Linux processes
... languages. With the use of TightVNC, it can also checkpoint and restart X-Window applications. The OpenGL library for 3D-graphics is supported through a special plugin. It also has strong support for HPC (High Performance Computing) environments, including MPI, SLURM, InfiniBand, and other components.
An "Alternative IO" layer.
The alio library can be dynamically pre-linked to existing executables and replaces file IO (i.e. calls to glibc's IO functions). This allows to gather statistics about IO, create IO trace files, or even implement a different IO behaviour (e.g. use separate IO servers to handle IO).
Dynamic Re-configurable Autonomous Many-task Simulator
DReAMSim provides a simple simulation framework for modeling homogeneous and/or heterogeneous (re)-configurable processing elements in a large-scale distributed environment. In particular, DReAMSim enables users to model task scheduling techniques at a preliminary design stage in order to investigate their performance potential. The simulation framework makes it easy to extract various performance and resource utilization related statistics to study the behavior of different task scheduling...
The Open Pervasive Computing Environment facilitates the creation of distributed context-sensitive systems (inc. embedded). It provides a number of frameworks for creating complex event processing systems driving the development of ubiquitous technology.
BitDHT is a LGPL'd general purpose C++ Distributed Hash Table library. It is designed to take hassle out over creating your own DHT. BitDHT is compatible with bitttorrent's DHT and can leverage this network to bootstrap your own personal DHT.
JOST is high performance JSON Parser and Generator written in C++ and relying on the BOOST Library. The current version is also being extended with a high performance caching service for JSON objects.
