ARC 15.03 update 15

Description

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.

ARGUS 1.7.1

Description

Argus is a system meant to render consistent authorization decisions for distributed services (e.g. compute elements, portals). In order to achieve this consistency a number of points must be addressed. First, it must be possible to author and maintain consistent authorization policies. This is handled by the Policy Administration Point (PAP) component in the service. Second, authored policies must be evaluated in a consistent manner, a task performed by the Policy Decision Point (PDP). Finally, the data provided for evaluation against policies must be consistent (in form and definition) and this is done by the Policy Enforcement Point (PEP).

CREAM 1.16.5

Description

The CREAM (Computing Resource Execution And Management) Service is a simple, lightweight service that implements all the operations at the Computing Element (CE) level; its well-defined WebService-based interface and its implementation as an extension of the Java-Axis servlet (running inside the Apache Tomcat container) provide interoperability with clients written in any programming language and running on any computer platform.

The CREAM interface is well-defined using the Web Service Description Language (WSDL); anyone can generate his/her CREAM client by simply filling in the stub code generated by WSDL parser (gSOAP for C/C++, Axis for Java, Perl module for perl).
