of CCGrid |
| The 3rd IEEE/ACM International Symposium on Cluster Computing and the Grid (CCGrid 2003) |
Two new paradigms are changing the way we do computing: Clusters and Grids. Both have been born by the need for more economical means for high-performance computing. Clusters employ cost-effective commodity components for building powerful
computers, and Grids allow to better utilize the computing resources that are available via Internet.
CCGrid2003, sponsored by the IEEE Computer Society Task Force on Cluster Computing, is designed to bring together international cluster and grid computing researchers, developers, and users to present and exchange the latest innovations and findings that drive future research and products. |

[Abstract]
Grid technology enables us to share wide variety of computational resources on the Internet.In the grid environment, users often need a convenient method to safely share data in storages, each of which is separately located across untrusted public network. However, few existing grid file transfer services balance a trade-off between convenience and security, and it makes difficul to deal with confidential data on the grid. To solve such problems and satisfy users' demands, we have developed an user-oriented-secure filesystem seamlessly integrated to the grid environment. The filesystem has been developed based on the two key technologies. One is Grid Security Infrastructure (GSI) provided by the Globus Project. The other is Self-certifying File System (SFS), a secure network filesystem developed at Massachusetts Institute of Technology. We combined the two to develop a new user-oriented-secure filesystem, or GSI-SFS.

| A Grid-enabled System
for Analysis of Brain Function |

[Abstract]
In these day, Grid technology gains recognition everywhere in both scientific and business fields. In particular, brain scientists and doctors strongly seek highly sophisticated Grid technology. In reality, however, they have much difficulty in making use of the Grid because of its complexity. Therefore, they expect a mechanism that hides the complexity and provides transparent access to computational resources on the Grid.
From the viewpoint described above, we have developed a mechanism that controls a flow from submitting jobs to downloading results based on priority that a user specified at the job submission. And we have designed and implemented an application on this mechanism as a web-based system that helps scientists and doctors to analyze brain function and diagnose. Thus, the complexity of the Grid is hidden behind the web interface. This system helps scientists and doctors adequately and efficiently perform the analysis and diagnosis of brain function.

| A Secure Grid Environment
using IPsec on IPv6 |
| Hongyu Shi : Graduate School of Information Science and Technology, Osaka University |
[Abstract]
Grid is a technology that can dynamically integrates various elements, such as processor resources including PC and WS and data storage, on a network to build a unified system that can be shared among many users. Now Grid technology equipped with new functionalities to realize a form of advanced collaboration and to achieve dramatic cost reduction has been used not only for a scientific field but also for business. Given such circumstance, what is required is that users can access to the Grid in a safe and robust way. In this research, a secure Grid environment is proposed and constructed by applying a suite of security solutions to the Grid environment. The solutions have adopted IP security (IPsec) and Internet Key Exchange (IKE) as base technology. Furthermore, in this paper, our secure Grid environment is realized on IPv6 network, so that our Grid environment addresses the shortage of IPv4 addresses. In ccgrid2003, we introduced the techiniques to build a secure Grid environment on an IPv6 network and its mechanism in detail.

| The Development of Data Grid Environment for Neuroinformatics |

[Abstract]
Neuroinformatics is a new research area that will help to accelerate progress in understanding human brain. This research area combines neuroscience and informatics. To promote neuroinformatics, a network is necessary to connect data, analysis tools and numerical models for neuroscience and brain science dispersed in various research organizations. We recognize that fundamental methods for promoting neuroinformatics are data description, accumulation and distribution. Currently, we are targeting on MEG (Magnetoencephalography) as an experimental device. MEG is a device that has the ability to detect the change in minute magnetic fields generated from the brain activity. Sharing MEG data through unified format corresponds to the purpose of neuroinformatics. In CCGrid2003, we plan to illustrate our data sharing system using OGSA-DAIS of Global Grid Forum Data Access and Integration Working Group, and will apply to MEG data sharing and analysis.
