Open Source

The open source Globus Toolkit is a fundamental enabling technology for the "Grid," letting people share computing power, databases, and other tools securely online across corporate, institutional, and geographic boundaries without sacrificing local autonomy. The toolkit includes software services and libraries for resource monitoring, discovery, and management, plus security and file management.

Jini.org is a central place and resource for the Jini CommunitySM. It is a site to discover new information, discuss, collaborate, exchange source code and ideas, and advance Jini™ network technology.
Jini network technology is an open software architecture that enables the creation of network-centric solutions which are highly adaptive to change.

UNICORE (Uniform Interface to Computing Resources) offers a ready-to-run Grid system including client and server software. UNICORE makes distributed computing and data resources available in a seamless and secure way in intranets and the internet.

OSCAR (Open Source Cluster Application Resources) is a snapshot of the best known methods for building, programming, and using HPC clusters. It consists of a fully integrated and easy to install software bundle designed for high performance cluster computing. Everything needed to install, build, maintain, and use a Linux cluster is included in the suite, making it unnecessary to download or even install any individual software packages on your cluster.

The aim of the OGSA-DAI project is to develop middleware to assist with access and integration of data from separate sources via the grid. The project was conceived by the UK Database Task Force and is working closely with the Global Grid Forum DAIS-WG, the OMII and the Globus team.

openQRM is designed to deal with all sorts of failures automatically, thus preventing interrupts because of unexpected events.
Implementing openQRM greatly improves the reliability of the x86 data-center.
openQRM is an open source systems management platform which integrates with existing components in enterprise data centers to create scalable, highly available and customizable infrastructures.

The objective of this workpackage is to design and build a Grid Application Toolkit (GAT) and to plug-in to this GAT the services developed in other GridLab workpackages.
GAT is a set of coordinated, generic and flexible APIs for accessing Grid services from e.g. generic application codes, portals, data managements systems, together with working implementations provided by the tools developed in the Grid Lab project (See the figure below). GAT is designed in a modular plug-and-play manner, such that tools developed anywhere can be plugged into GAT.

Alchemi is an open source software framework that allows you to painlessly aggregate the computing power of networked machines into a virtual supercomputer (desktop grid) and to develop applications to run on the grid.

It has been designed with the primary goal of being easy to use without sacrificing power and flexibility.

Alchemi includes:
The runtime machinery (Windows executables) to construct computational grids.
A .NET API and tools to develop .NET grid applications and grid-enable legacy applications.

Crossbow provides the building blocks for network virtualization and resource control by virtualizing the stack and NIC around any service (HTTP, HTTPS, FTP, NFS, etc.), protocol or Virtual machine.

Each virtual stack can be assigned its own priority and bandwidth on a shared NIC without causing any performance degradation. The architecture dynamically manages priority and bandwidth resources, and can provide better defense against denial-of-service attacks directed at a particular service or virtual machine by isolating the impact just to that entity. The virtual stacks are separated by means of H/W classification engine such that traffic for one stack does not impact other virtual stacks.

Project Crossbow is next step in the evolution of Solaris networking stack and brings bandwidth resource control and virtualization as part of the architecture itself instead of the usual add-on layers which have heavy overheads and complexity.

Solr is an open source enterprise search server based on the Lucene Java search library, with XML/HTTP and JSON APIs, hit highlighting, faceted search, caching, replication, and a web administration interface. It runs in a Java servlet container such as Tomcat.

Hadoop is a software platform that lets one easily write and run applications that process vast amounts of data.

Talend Open Studio, the industry’s first pure open source data integration solution, combines metadata-driven design and execution, with an easy-to-use graphical development environment, to deliver better scalability at a lower total cost of ownership than traditional data integration or Extract, Transform and Load (ETL) solutions. Talend’s technology and business vision shatters the traditional proprietary model and provides the flexibility required to meet the needs of all organizations – regardless of their size, level of expertise or budgetary constraints.
