ARC 15.03 update 15
The Advanced Resource Connector (ARC) middleware is an Open Source software solution to enable distributed computing infrastructures with the emphasis on processing large volumes of data. ARC provides an abstraction layer over computational resources, complete with input and output data movement functionalities. The security model of ARC is identical to that of Grid solutions, relying on delegation of user credentials and the concept of Virtual Organisations. ARC also provides client tools, as well as API in C++, Python and Java.

The frontier-squid software package is a patched version of the standard squid http proxy cache software, pre-configured for use by the Frontier distributed database caching system. This installation is recommended for use by Frontier in the LHC CMS & ATLAS projects, and also works well with the CernVM FileSystem. Many people also use it for other applications as well
The project name Lcgdm comes from the first Grid-related projects, and originally meant LHC Computing Grid Data Management. Nowadays the project evolved from its initial roots, and is composed by a set of sub projects facing different aspects of data management for high throughput, widely distributed computing
