[geclipse-dev] GRIA 5.2 released

["Ken Meacham" <kem@xxxxxxxxxxxxxxxxxxxxxxxxx>]

We are pleased to announce that GRIA 5.2 is now available for download
from www.gria.org. 

GRIA 5.2 provides significant feature enhancements to the Basic and
OGSA-DAI application service packages along with usability and
performance enhancements to other packages.

The Basic Application Services package has been enhanced to improve
interoperability and the integration of cluster computing facilities:

* Supports the Job Specification Description Language (JSDL):
	* Users can define their processing requirements in a
standardised way.
	* JSDL compliant Resource Managers can be integrated easily.
* Multiple resource managers can now be connected to a single GRIA
service provider.
* Resource Managers and applications can report usage to the SLA
management service.
* Application metadata schema has been extended and includes:
	* optional and variable numbers of inputs and outputs, 
	* command line descriptions,
	* extensibility points for application specific extensions. 

The GRIA 5.2 OGSA-DAI service which integrates with OGSA-DAI WS-I 2.2
can now be customised to support any back-end data resources supported
by OGSA-DAI itself.  The service is managed using GRIA's SLA service and
policy framework and, in addition to the previous release, can now take
full advantage of the client management system.  Data resource access
can be controlled through membership groups and clients can use the
resources through the standard OGSA-DAI API.

GRIA 5.2 is compatible with previous GRIA 5.x releases. In addition,
users with existing GRIA 5.x installations are provided with an
automated upgrade capability executed when GRIA is deployed within the
service container.
