The ENBD (Enhanced Network Block Device) is an industrial-strength version of the Linux kernel NBD. It makes a remote disk look like a local block device, allowing cheap and safe realtime mirrors to be built over the net. It features internal block-journalling and multichannel failover.
Enhanced Cluster Tools (ECT) for Linux is a set of additional tools for the enhancement of Cluster Systems Management (CSM), which assists an administrator in managing a whole set of Linux machines. ECT for Linux includes features such as parallel install, hardware control, configuration file management, event monitoring, and more that help make it easier for an administrator to set up and maintain machines.
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.
The ExtenDB Parallel Server is a clustered database solution for data warehousing and business intelligence. It leverages the PostgreSQL database running on PC-based commodity hardware, and intelligently coordinates work between them. This allows for the scaling out of databases to handle large data volumes quickly.
FAI (fully automatic installation) is a non-interactive system to install a Debian GNU/Linux operating system on a group of PCs or a Linux cluster. After installation, the systems are fully configured and ready to run. It is a scalable method for performing unattended installation and updating. Changes to the configuration files of the operating system are made by cfengine, shell, and Perl scripts.
FREP is an application which can be used to keep files in a cluster of servers synchronized from a centralized location. Under the hood, it uses the Spread toolkit (broadcast/multicast traffic), libevent/epoll, sendfile, inotify, intelligent file transfers using the generic diff format, and zlib compression.
The "Faster Java Serialization" project aims to provide faster Java serialization by inspecting classes and generating tailor made serialization code on the fly. This serialization code is reused for every object of the same class. Objects are serialized to a NIO ByteBuffer, eliminating the need for numerous memory copies that take place during normal serialization to files or network. Currently, there are some limitations on the kinds of objects that can be serialized.
