DIPC allows an application programmer to easily (transparently) send and receive data, synchronise using semaphores, and use a shared memory over a network. Distributed computing is thus made very easy. DIPC modifies System V's message queues, semaphores, and shared memory segments so that they can operate not just within a single computer, but over a cluster of computers. The programming model is very similar to that of a group of processes running on the same computer and exchanging data.
Chiron FS is a FUSE based filesystem that implements replication at the filesystem level like RAID 1 does at the device level. The replicated filesystem may be of any kind you want; the only requisite is that you mount it. There is no need for special configuration files; the setup is as simple as one mount command (or one line in fstab).
xlike is a patch collection for the Linux vanilla kernel. It includes as many stable enhancements for the Linux kernel as possible. These include code from Xen, Kernel Mode Linux, Rule Set Based Access Control, Novell AppArmor, Openswan, grsecurity, Linux VServer, Linux-PHC, web100, Nefilters, Suspend2, Speakup, SquashFS, UnionFS, Bootsplash, BadRAM, and more. It also contains many drivers and fixes.
OpenVPS is a set of software built on top of the Linux VServer aimed specifically at Web Hosting. It is not another set of kernel patches, but a set of scripts to create virtual servers, collect resource utilization information, and provide an interface to the customer as well as the administrator.
Kerrighed is a Single System Image operating system (SSI) for clusters. It offers the view of a unique SMP machine on top of a cluster of standard PCs. The goals are high performance of applications, high availability of the cluster, efficient resource management, high customizability of the operating system, and ease of use. It is implemented as an extension to Linux operating system (a set of Linux modules and a small patch to the kernel).
The Beowulf Distributed Process Space (BProc) is set of kernel modifications, utilities, and libraries which allow a user to start processes on other machines in a Beowulf-style cluster. Remote processes started with this mechanism appear in the process table of the front end machine in a cluster. This allows remote process management using the normal UNIX process control facilities. Signals are transparently forwarded to remote processes and exit status is received using the usual wait () mechanisms.
openSSI webView is a simple and easy-to-use openSSI cluster monitoring system. Its goal is to provide a quick overview of the cluster state by graphing vital functions and graphically representing key figures. It allows the cluster administrator to keep an eye on the cluster health and usage rate, to quickly view each node state and load, and to watch, and even migrate, users' processes all across the cluster.
v9fs provides a Plan 9 9P2000 resource sharing protocol for the Linux 2.6 kernel. This can be used to share files, devices, /proc, /sys, etc. It also works with Plan 9 file servers, and can be used to mount synthetic file systems from Plan 9 applications (see the plan9port project).
