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!

Recent progress of science and technology has made numerical simulation an important approach for studies in various fields. Although scalable and high performance numerical libraries on large scale computing resources are indispensable tools for handling various multiscale phenomena, few projects for integrating these numerical libraries have been reported. The object of this project is the development of a basic library of solutions and algorithms required for large scale scientific simulations, which have been developed separately in each fields, and its integration into a scalable software infrastructure. The components include a scalable iterative solvers library Lis, having a number of solvers, preconditioners, and matrix storage formats that are flexibly combinable, a fast Fourier transform library FFTSS for various superscalar architectures with SIMD instructions, which outperforms some vendor-provided FFT libraries, and a language- and computing environment-independent matrix computation framework SILC. We show some highlights of our achievements on leading high performance computers.

Over the past decade, commodity computing and Linux have helped to significantly transform supercomputing. Fueled by the open source model, collaboration of the supercomputing community has had far reaching affects on enterprise computing. In his talk, Matthew Szulik (Chairman and CEO of Red Hat) will draw parallels between open source trends in supercomputing and the advancement of enterprise computing. As we look ahead, he will discuss how meeting the future's computing challenges will require faster innovation driven by better collaboration.

"Clustered Storage is becoming pervasive and is a major paradigm shift from previous generations of storage products, much like when CDs made records obsolete." ~ Tony Asaro, Enterprise Strategy Group, Oct 2005The purpose of this presentation is to introduce you to a new paradigm shift that is currently taking place in the data storage industry: the movement toward Clustered Storage architectures. Distributed storage clustering for the data storage industry is in much the same position today that IBM was in 1981, poised to change the rules of the computer industry. Clustered Storage architectures are changing the rules of how data is stored and accessed. In this paper we will discuss the trends that clearly define clustered storage architectures as the future of data storage, detail the requirements of this new category of storage, and introduce the Isilon® IQ clustered storage solution which is the first to deliver on the promises of this paradigm shift.
“集群存储正变得越来越普遍，与前几代存储产品相比，这是一种重大的范式转变，就像cd使唱片过时一样。”~ Tony Asaro, Enterprise Strategy Group, 2005年10月本演讲的目的是向您介绍当前数据存储行业中正在发生的一种新的范式转变:向集群存储架构的转变。今天，数据存储行业的分布式存储集群所处的位置与1981年IBM所处的位置非常相似，即准备改变计算机行业的规则。集群存储架构正在改变数据存储和访问的规则。在本文中，我们将讨论将集群存储架构明确定义为数据存储的未来的趋势，详细介绍这种新存储类别的需求，并介绍Isilon®IQ集群存储解决方案，这是第一个实现这种范式转变的承诺。

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.

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.

This BOF will continue debate revolving around productivity metrics for supercomputers. At several recent user forums, consensus emerged that it is not possible to develop petascale applications without interactive access to thousands of processors. But most large systems are managed via a batch scheduler with long (and unpredictable) queue wait times. Most batch scheduler policies assume high system utilization as "good". But high utilization dilates average queue wait time and increases wait-time unpredictability, both of which are "bad" for application developer's productivity. What are the options to address these conflicting implications for running a supercomputer at high system utilization? Is it possible to manage a supercomputer to meet the high-throughput demands of stable applications and the on-demand access requirements of large-scale code developers concurrently? Or do these two usage scenarios inherently conflict? Participants will explain and debate several creative solutions that could enable high throughput and high availability for program development.

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.

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.
