Human-robot interaction (HRI) spans many and diverse contexts, each varying in the preferred degree of social connection fostered therein. The design of robotic systems and selection of which robotic forms to use will thus benefit from an understanding of the factors by which social connection is enhanced or diminished. We address this fundamental problem through an exploratory study of role-taking, a core construct from structural social psychology. Through a laboratory experiment (N=86) in which participants interact with either human, humanoid robot, or non-humanoid robot partners, we examine variation in perceived role-taking accuracy, affection for the partner, and desire for continued interaction. Findings show that participants evaluate human interaction partners as more accurate role-takers than robots, but with variation between robotic types (humanoid vs non-humanoid) in relation to personality versus emotion. Sense of affection and desire for continued interaction are predicted by interpersonal factors rather than partner type or robotic form. We discuss possible reasons behind these preliminary findings and draw on them to formulate subsequent research questions. More broadly, we call for continued study at the intersection of HRI and structural social psychology, advancing both fields through the pairing.

Compframe is an open international organization of framework and component framework developers representing many of the major efforts in HPC today. The purpose of this BOF is to assemble developers of framework and component frameworks for high performance computing. Application developers and users of these frameworks are also welcome in the context of user experience, desired enhancements, horror stories, etc. Discussion will center design patterns, methodologies, user experience and interoperability with these tools. Of particular interest is the viability of these frameworks for petascale applications on the next generation leadership class hardware coming on line soon. Also under discussion is the possiblity of a follow-on workshop, its date, venue, content and the publication of proceedings.

A data warehouse provides a customer with information to run and plan their business. It is true that if the data warehouse cannot quickly adapt to changes in the environment then the company will lose the advantage that information provides. A warehouse must be built with a solid foundation that is flexible and responsive to business changes. The purpose of the paper is to share experiences in the area of managing the growth within the data warehouse. There are many technical issues that need to be addressed as the data warehouse grows in multiple dimensions. The ideas in this paper should enable you to provide the correct foundation for a long term warehouse. Very few companies are discussing these issues and the lack of discussion leads to a lack of knowledge that will further lead to poor architectural choices. The paper articulates not only the benefits that are derived from data warehousing today but how to prepare to reap benefits for many tomorrow's. It also explores the questions to ask, the points to make, and the issues to be addressed to have a long term successful data warehouse project.

DAISy (Distributed Array of Inexpensive Systems) is a 16 node PC cluster running a full Unix compatible operating system. The network media used includes standard 10 Mb/s (10BASE-2) Ethernet (used for client node NFS mounts and any client node interactive work users find necessary), and, switched 100 Mbs/(100BASE-TX) Fast Ethernet (used for user program message passing traffic). The DAISy cluster is used to investigate the viability of commodity PC technology to perform computation of scientific and engineering problems traditionally performed on "supercomputers", and more recently high performance RISC workstations and clusters of RISC workstations. Performance analysis of the various single node subsystems were carried out along with performance analysis of the cluster as a whole on a number of parallel applications. The results show that the current Pentium 90 MHz CPU and motherboards used are well within that of many low end workstations offered by traditional workstation vendors.
