footprint is a tool that makes it easier to create and manage kickstart files. It allows you to define systems, create profiles for systems, and macros per distribution. It can create kickstart files on the fly, make custom initrd (ramdisks), create custom bootfloppies, and can manage your DHCP and PXE configuration.
SLURM is a resource manager designed for Linux clusters of all sizes. It provides three key functions. First, it allocates exclusive and/or non-exclusive access to resources to users for some duration of time so that they can perform work. Second, it provides a framework for starting, executing, and monitoring work (typically a parallel job). Finally, it arbitrates conflicting requests for resources by managing a batch queue of pending work.
PigeonReader is the Web mail client of the PigeonAir project, a solution for easily building clustered, scalable, and modular email services. PigeonReader is completely UTF-8 compliant, allowing any charset to be used. It is based on XML, which allows skins and themes to be easily written using the XSLT language. It was written to be easily used in a cluster of Web servers, where multiple and different domains are to be managed transparently to the end user, possibly with different skins, features, and configurations.
PigeonAdmin is the mail administration interface of the PigeonAir project, a solution for easily building clustered, scalable, and modular email services. PigeonAdmin allows many virtual domains of the mail server to be easily managed using a simple Web interface. It allows every domain to have a different configuration than any other. It also allows domain administrators to choose which configurations to force on their own users or which parameters the users will be able to configure and modify by themselves.
PigeonDeliver is the delivery agent of the PigeonAir project, a solution to easily build up clustered, scalable, and modular email services. PigeonDeliver is modular in nature, allowing it to be used on Postfix and other MTAs using their own native APIs without performance loss. It allows mail services to be easily and transparently distributed among a cluster of mail server, easily supporting new services and new modules added using the PigeonDeliver API, which simplifies writing filters and/or delivery agents.
The DNServer class can be used to implement domain name servers (DNS). It starts listening to DNS UDP port 53 to handle domain name resolution requests. The class decodes the DNS request, and invokes a configurable callback function that takes the DNS query type and the domain to resolve and returns an IP address.
MultiLoad is a load balancer that redirects HTTP requests to pre-defined servers/locations. It gives the provider a way to balance the traffic and hides the real download location. It allows you to manage different version of each download. It is also a load balancing server extension. You can distribute files on some servers so that a downloaded file can be loaded form different servers. These servers can have different priorities to control the active traffic.
PMS/PyPubSub (short for Python Message Service / Python based Publish Subscribe) is a framework for implementing a publish subscribe mechanism into a Python application. A python process somewhere in the network publishes one or more topics which consist of Python objects. Multiple processes in the network can subscribe to fresh updates of the published topics. A publisher and its subsribers are fully decoupled. The datatype of a topic can be freely defined and changed at runtime. New publishers and subscribers can easily be added at runtime.
Clusterix is cluster software for Unix. It is intended for use with 2 machines for high availability services. For example, you can have a Web server with 2 nodes, or a database with shared disk. To put more than one service in high availability so that one service stays on one node and the second on the other node, you can simply make 2 installations of Clusterix in 2 different directories on the 2 nodes. When there is a failure of service on one node, the cluster system moves the service to the other node.
