Status of the LCG Physicist Interface (PI) project

In the context of the LHC Computing Grid (LCG) project, the Applications Area develops and maintains that part of the physics applications software and associated infrastructure that is shared among the LHC experiments. In this context, the Physicist Interface (PI) project of the LCG Application Area encompasses the interfaces and tools by which physicists will directly use the software. At present, the project covers analysis services, interactivity (the “physicistʹs desktop”), and visualization. The project has the mandate to provide a consistent set of interfaces and tools by which physicists will directly use the LCG software. This paper will describe the status of the project, concentrating on the activities in relation to the Analysis Services subsystem.
