FAYE: A Java Implement of the Frame/Stream/Stop Analysis Model

FAYE, The Frame AnalYsis Executable, is a Java based implementation of the Frame/Stream/Stop model for analyzing data. Unlike traditional Event based analysis models, the Frame/Stream/Stop model has no preference as to which part of any data is to be analyzed, and an Event get as equal treatment as a change in the high voltage. This model means that FAYE is a suitable analysis framework for many different type of data analysis, such as detector trends or as a visualization core. During the design of FAYE the emphasis has been on clearly delineating each of the executable's responsibilities and on keeping their implementations as completely independent as possible. This leads to the large part of FAYE being a generic core which is experiment independent, and smaller section that customizes this core to an experiments own data structures. This customization can even be done in C++, using JNI, while the executable's control remains in Java. This paper reviews the Frame/Stream/Stop model and then looks at how FAYE has approached its implementation, with an emphasis on which responsibilities are handled by the generic core, and which parts an experiment must provide as part of the customization portion of the executable.

IceCube's Development Environment

When the IceCube experiment started serious software development it needed a development environment in which both its developers and clients could work and that would encourage and support a good software development process. Some of the key features that IceCube wanted in such a environment were: the separation of the configuration and build tools; inclusion of an issue tracking system; support for the Unified Change Model; support for unit testing; and support for continuous building. No single, affordable, off the shelf, environment offered all these features. However there are many open source tools that address subsets of these feature, therefore IceCube set about selecting those tools which it could use in developing its own environment and adding its own tools where no suitable tools were found. This paper outlines the tools that where chosen, what are their responsibilities in the development environment and how they fit together. The complete environment will be demonstrated with a walk through of single cycle of the development process.

Concrete uses of XML in software development and data analysis

XML is now becoming an industry standard for data description and exchange. Despite this there are still some questions about how or if this technology can be useful in High Energy Physics software development and data analysis. This paper aims to answer these questions by demonstrating how XML is used in the IceCube software development system, data handling and analysis. It does this by first surveying the concepts and tools that make up the XML technology. It then goes on to discuss concrete examples of how these concepts and tools are used to speed up software development in IceCube and what are the benefits of using XML in IceCube's data handling and analysis chain. The overall aim of this paper it to show that XML does have many benefits to bring High Energy Physics software development and data analysis.
