Ecological networks comprised of diverse species interacting within habitats describe iconic self-organized complex systems. Their nodes are dynamic, highly heterogeneous and constantly evolving in response to their changing environment. Yet, these ungoverned highly diverse and complex ecological networks remain remarkably robust despite catastrophes that destroy huge fractions of the nodes and cause permanent alterations of the environment. Recent work to model these system employs network informatics, visualizations, and high performance computing simulations. Exploring these models demands that the parameters are both fit using rigorous informatics and also varied in innumerable combinations using efficient and powerful computer architectures. This presentation will describe the mechanics of this endeavor as well as several of the most interesting research results including the robustness enhancing roles of network architecture and organism's size and behavioral nonlinearities as well as network effects of species' loss and invasions. A particular future for such endeavors will also described with special attention to implications for general network science.

The size of High Performance Compute Clusters has been growing rapidly, sometimes scaling to tens of thousands of nodes. A key aspect of HPC performance is the characteristics and performance of the network. Within HPC, each node within the cluster needs to be able to communicate with other resources - storage, for example - and with other nodes in the cluster for control and inter-process communications. As a cluster scales in size, careful consideration with respect to IPC, management and storage access is required to ensure the highest application performance and availability.This session will present best-practices for building large networks to support the most demanding HPC environments, and includes proven design recommendations for building scalable Ethernet, InfiniBand and Storage fabrics. Additionally, troubleshooting techniques, tips and tools to simplify management of infrastructure will be discussed in this session.

Nanotechnology is an exciting field with many potential applications. Its impact is already being felt in materials, engineering, electronics, medicine, and other disciplines. Current research in nanotechnology requires multi-disciplinary knowledge, not only in sciences and engineering but also in high performance computing (HPC) technology. Many nano-science explorations rely on mature, efficient HPC and computational algorithms, practical and reliable numerical methods, and large-scale computing systems. This workshop offers academic researchers, developers, and practitioners an opportunity to discuss various aspects of HPC-related computational methods and problem solving techniques for nano-science and technology research.

This workshop will focus on projects and technologies that are adopting scientific portals and gateways. These technologies are characterized by delivering well-established mechanisms for providing familiar interfaces to secure Grid resources, services, applications, tools, and collaboration services for communities of scientists. In most cases access is enabled through a web browser without the need to download or install any specialized software or worry about networks and ports. As a result, the science application user is isolated from the complex details and infrastructure needed to operate an application on the Grid.

Scatter/Gather is designed to stimulate is a very open dialog of new ideas and emerging work. This is your chance to tell everyone about your new idea! This year we'll modify the format a bit to more closely resemble an "un-conference" in which the meeting is driven and created dynamically by the participants. We'll use a whiteboard to self-organize so look for the sign-up display at the conference near the registration area -- but don't delay because time-slots are limited and it's first-come, first-served. Remember, the idea is to share and get feedback on your ideas, not make a polished presentation!

NEC is a leading solutions provider of high performance computers. NEC understands that one size does not fit all and one hardware architecture can not be optimal for all applications. NEC has a rich experience in integrating powerful vector supercomputers with industry standard systems to build tailored solutions. The presentation will introduce the NEC SX vector supercomputer series and give examples of powerful solutions that have been built with it.

First-principles simulations of high-Z metallic systems using the Qbox code on the BlueGene/L supercomputer demonstrate unprecedented performance and scaling for a quantum simulation code. Specifically designed to take advantage of massively-parallel systems like BlueGene/L, Qbox demonstrates excellent parallel efficiency and peak performance. A sustained peak performance of 207.3 TFlop/s was measured on 65,536 nodes, corresponding to 56.5% of the theoretical full machine peak using all 128k CPUs.

The latest WAN infrastructure and Grid-based Web Services will be used to demonstrate movement and analysis of TeraByte-scale event datasets for particle physics. Optimized transfers of data over 10Gbit/sec networks linking servers and disk systems will be shown using the latest processors, PCI-Express NICs, RAID arrays and firmware. All available lambdas arriving at the SC06 show floor will be saturated, in full duplex mode. The WAN performance will be monitored using the MonALISA distributed agent-based system. A suite of Grid-enabled Analysis tools developed at Caltech, University of Florida and Michigan will be used, as will. EGEE, OSG, ATLAS and CMS data management software such as SRM, dCache, FTS, and PhEdEx. Prototypes of the latest version of parallel NFS will demonstrate excellent utilization of 10Gbit/sec connections during execution of the analysis tasks.We intend to exceed the aggregate rate of 150Gbits/sec we achieved in our SC2005 Bandwidth Challenge winning entry.
