Call for Position Papers:
Increasingly, scientists are using portals and desktop applications as "gateways" to access computation, information, and even instruments that are integrated within Grid systems. The concept of a "Science Gateway" is a community-specific set of tools, applications, and data collections that are integrated together via a portal or a suite of applications, providing access to Grid-integrated resources. These gateways often support orchestrated workflow, resource directories (databases, compute resources, etc.), and execution services. As more and more communities build science gateways, it will be useful to develop a set of conventions - policies, technical approaches, interactions - by which a science gateway interacts with a Grid or with a Grid resource.
The purpose of the workshop is to bring together researchers or resource providers who are trying to bring or have brought Grid capabilities to a particular science community (atmospheric scientists, chemists, bioinformaticists, etc.), and who are doing this by:
* building portals
* implementing web services on resources in operational grids
* building applications with "embedded" capabilities to access Grids (or Grid resources) from the desktop

We will explore and summarize commonalities and differences among development approaches and technologies used as well as system, security, accounting, authentication/authorization and other policies and capabilities that need to be in place to support these interfaces on production grids.

We are looking for brief (3-5p) position papers that cover the following topics:
* Description of services provided by the interface and technologies/software used to provide them
* Description of specific configuration or policy issues encountered during deployment and maintenance of these interfaces
* Authentication and authorization approaches to allow a variety of user "types" ranging from fully authenticated to anonymous users of restricted access such as running a tool on a Grid resource from a portal interface.
* Practical issues related to supporting workflow on Grid resources
* Approaches to providing web services on a secure system, including mechanisms and techniques for enabling gateway developers to manage and provide applications on computational resources for execution as web services

Typical services provided might include community data resources, visualization or data analysis capabilities, applications and compute resources, collaboration spaces and workflow tools. For the workshop presentations, we are seeking position papers on the subjects described above. Papers should be typeset in a single-column format, in 12pt font, for letter or A4 sized paper. Papers should not exceed 5 pages. Submission format is PDF.

Please submit your paper to marked as GGF-14 Science Gateway workshop submission.
Publication: All accepted submissions will be used, along with workshop notes, to prepare a report that will be published as a GGF Informational Document or may be submitted to a journal covering Grid computing.

Important Dates:
Paper submission: May 23, 2005
Notification of acceptance: May 27, 2005
Workshop: June 28, 2005
Participants will be required to register according to the arrangements to be set for this purpose by GGF. See for registration information.

8th April 2005 - the GridLab project is among the most successful FP5 projects

26th November 2004, Ibis 1.0 released!
We are happy to announce that Ibis 1.0 has been released. It can be downloaded from

The goal of the Ibis project at the Vrije Universiteit Amsterdam is to design and implement an efficient and flexible Java-based programming environment for Grid computing, in particular for distributed supercomputing applications. Java has many advantages for Grid computing. Foremost, by being based on a virtual machine concept, it is inherently more portable than traditional, statically compiled languages, making it much easier to execute Java applications in a heterogeneous Grid environment. Also, Java is based on a high-level, object-oriented, type-safe programming model and it has built-in support for multi-threading and distributed computing. Unfortunately, Java's support for distributed computing, Remote Method Invocation (RMI), has important shortcomings for high-performance Grid computing: it is difficult to implement efficiently and only expresses client-server style communication. Ibis addresses these problems. Ibis boosts RMI performance using several optimizations, especially to avoid the high overhead of runtime type inspection that current RMI implementations have. Ibis comes with a highly efficient serialization implementation. The Ibis project also addresses the lack of expressiveness of Java RMI, which provides only synchronous client-server communication. The Ibis programming environment supports a range of communication paradigms, including group communication, divide-and-conquer and collective communication, integrated cleanly into Java. Other systems typically resort to extensions that are less well integrated with Java's object-oriented model, such as using a native MPI library. An additional nice feature of Ibis is that it can communicate through firewalls, without opening ports. Ibis is free software (BSD-style license). It runs on any platform that has a Java 1.4 or higher JVM.

15th June 2004, PSNC to Productize GridLab software
During the Dissemination and Exploitation GridLab review in Brussels - Jarek Nabrzyski, the GridLab project coordinator, Poznan Supercomputing and Networking Center, Poland (PSNC), will announce PSNC's plans to bring GridLab software and some other European and US Grid open source solutions to market by the mid of 2006. GridSuite, the out of the box complete Grid solution will Bring grid tools and services for both, Grid application developers and Grid deployers from academia, business and industry. PSNC will work very closely with all the GridLab partners to bring high quality GridSuite system, consisting of such tools as the Grid Application Toolkit, Grid Resource Management System, Grid Monitoring System, Grid Data Management System, Grid Authorization System, Grid Mobile User System, Grid Adaptive System, Grid Information System and GridSphere Portal Framework and productized version of the Globus software. Some other packages include (but are not limited to) the Grid Virtual User Accounting System (VUS) and Grid Virtual Desktop system, both from PSNC. PSNC will devote substantial resources to implement GridSuite. The main advantage of using the GridSuite system will be reduction of operating costs of the companies by optimizing hardware resources and minimizing the application development costs by introducing high level grid API for application developers. The key to the success will be the Grid Resource Management System (GRMS) that together with other Grid services and tools will bring the best possible performance to applications on one side and the best utilization of the resources on the other one. The Grid API, based on the GridLab's GAT, will allow application developers to grid-enable their application in fast and robust way.
The license for the GridSuite software is still not defined, but Nabrzyski says that PSNC works on the business plan for GridSuite. All the details will be known by the end of 2004.

Scientific Computing April 2004, GridLab in Scientific Computing World

"It seems to be my lot in this slot to parade my ignorance of hot topics. My excuse is that the need to understand a new issue is a great incentive to venture out on to the web. Which is why I have been trying to pin down just what 'middleware' is all about. We first have to think about grid computing, which connects computers so that they can work together and operate as a distributed supercomputer. The computers in this grid can be anything that can contribute to the processing task to hand..."
