                                                    VLab Portals
 In support of VLab’s Grid middleware, we are building component-based portals that will simplify the complicated submission
 and code management problems involved in VLab research.
 Based on a core of standard Grid technology such as the Globus toolkit and the Java CoG kit, we are building advanced Web
 Services for workflow and job management. The VLab Web Portal serves as a client management environment to these service
 components. We build these portals out of standard components called “portlets”, following the model of the Open Grid
 Computing Environments (OGCE). Portlets allow entire user interface applications, such as components for submitting PWSCF
 and other QUANTUM ESPRESSO codes, to be bundled into a reusable, distributable component that may be easily installed in
 other portal systems. This allows us to share VLab-developed components with our international collaborators and vice versa.

   We are also investigating reusable
   portal components at a finer grain
   than portlets. By extending Sun’s
   Java Server Faces to support VLab
   Grid service clients, we will be able
   to greatly simplify the process of
   designing portlets themselves from
   reusable components. This will also
   allow us to work closely with
   component designers from other,
   unrelated portal efforts through the
   OGCE.

                                        VLab’s General Architecture
   VLab is a system aimed to allow geo-materials scientists to execute extensive workflows on top of distributed
   resources like databases or distributed computing nodes. It will also allow for monitoring executions and analyses
   of results. A crucial component is the VLab portal. It provides to the users the abstraction of a single system, while
   providing access to the underlying grid resources. It aggregates in a single site the interfaces of the several
   services used by the users to accomplish their workflows. It will also interface user transparent services like
   resource brokering and fault tolerance support.

                     VLab Undergraduate Internship Program - Summer 2005
 Professor David A. Yuen, Department of Geology and Geophysics.
 Project Description: Interns associated with David Yuen are working on visualization projects. One consists of visualizing and analyzing
 large geophysical datasets on the Powerwall display device. Amira and Paraview are the visualization software packages being used.
 Another project consists in developing a Web-service for allowing visualization from Paraview software to be rendered and observed by
 remote users through the middleware NaradaBrokering.

 Professor Donald G. Truhlar, Department of Chemistry
 Project Description:This project is about modeling various water systems. It involves determining how well
 different methods do at modeling water systems with an OH radical, and possibly improving some existing method
 for this purpose.

                                            IT Meeting at CINECA, Bologna
   This meeting aimed at connecting the Italian QUANTUM ESPRESSO (QE)
   development team with the VLab IT team. The QE public software package for
   electronic structure and materials properties computations will be accessible
   by means of portals through the VLab system.
