The overall objective of the XtreemOS project is the design, implementation, evaluation, and distribution of a grid operating system (called XtreemOS) with native support for virtual organizations (VO). XtreemOS is capable of running on a wide range of underlying platforms, from clusters to mobiles. It is based on Mandriva Linux, with support to come for other distributions later.
chunkd is a simple storage service based on the GET, PUT, and DELETE operations. It is meant to be used in building larger, replicated, distributed storage systems. Clients connect via TCP and remotely manage storage. Typical applications include distributed filesystems and other distributed storage applications.
Livespaces is an operating system for building advanced meeting spaces. It provides a distributed software infrastructure built on the Elvin messaging service (the Livespace Bus) for coordinating software and devices across any number of computers in a meeting space, and user-facing applications for controlling a smart meeting room and collaborating with other participants. It also supports federation with remote Livespaces to facilitate collaboration between distributed teams.
Makeflow is a workflow engine for executing large complex applications on clusters, clouds, and grids. It can be used to drive several different distributed computing systems, including Condor, SGE, and the included Work Queue system. It does not require a distributed filesystem, so you can use it to harness whatever collection of machines you have available. It is typically used for scaling up data-intensive scientific applications to hundreds or thousands of cores.
Parrot and Chirp are user-level tools that make it easy to rapidly deploy wide area filesystems. Parrot is the client component: it transparently attaches to unmodified applications, and redirects their system calls to various remote servers. A variety of controls can be applied to modify the namespace and resources available to the application. Chirp is the server component: it allows an ordinary user to easily export and share storage across the wide area with a single command. A rich access control system allows users to mix and match multiple authentication types. Parrot and Chirp are most useful in the context of large scale distributed systems such as clusters, clouds, and grids where one may have limited permissions to install software.
Wisecracker is a high performance distributed cryptanalysis framework that leverages GPUs and multiple CPUs. It allows security researchers to write their own cryptanalysis tools that can distribute brute-force cryptanalysis work across multiple systems with multiple multi-core processors and GPUs. Security researchers can also use the sample tools provided out-of-the-box. The differentiating aspect of Wisecracker is that it uses OpenCL and MPI together to distribute the work across multiple systems, each having multiple CPUs and/or GPUs.
Hados stores files in a cluster of servers. Its goal is to handle high availability by storing copies of the same file on several nodes. It provides RESTFUL APIs to easily store, check, or retrieve files. Using the cluster APIs, you can retrieve files from whichever node hosts them. To avoid any single point of failure, it is possible to apply a request to any node of the cluster; there is no master node.
