[CAnet - news] Science Gateways: Common Community Interfaces to Grid Resources

For more information on this item please visit the CANARIE CA*net 4 Optical

-------------------------------------------

[This is a very important workshop and I encourage anybody to participate
who is interested in network orchestration and how that is related to
cyber-infrastructure and service oriented architectures for science grids
and portals. To realize the vision of cyber-infrastructure we need tools
like workflow composition wizards, authentication portal and certificate
delegation, etc etc  -- BSA]

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.

Informational Document or may be submitted to a journal covering Grid 
computing.
