                Announcing Grid Engine 6.2 Beta Binaries
                  Regensburg, Germany -- May 13, 2008

Grid Engine 6.2 Beta courtesy binaries are now ready for download.

Grid Engine 6.2, which has undergone significant changes in qmaster to
significantly improve its scalability in challenging environments, adds
powerful features to the core system, introduces multi cluster support for
the Accounting and Reporting Console (ARCo) and comes with a new module
extending the scope of Grid Engine to a new domain of use cases: the 
Domain Manager (SDM), aka. project Hedeby allows to dynamically (re-)assign
computational resources on demand.

The courtesy binaries are available at


The corresponding source code tag in the CVS repository has the name
A snapshot of the sources is available at the Documents & Files page

The documentation and release notes are available at


What's new in Grid Engine 6.2

1. Service Domain Manager
2. New in Grid Engine "core" and Accounting and Reporting Console (ARCo)
3. Moving Grid Engine documentation set to http://wikis.sun.com

1. Service Domain Manager

This release adds a new module, extending the scope of Grid Engine to a new
domain of use cases: The Service Domain Manager (SDM), aka. project Hedeby
will allow to dynamically (re-)assign computational resources on demand
through configurable SLOs (Service Level Objectives), measured by KPIs (Key
Performance Indicators) of the managed resources. Through adapters it will
be possible to add virtually any type of service, be it for example a Grid
Engine cluster, an application server farm, other types of Grid middle ware
applications. Manageable resources can be e.g. physical or virtual hosts,
software licenses.

This release of SDM will support to manage two or more Grid Engine 
Futures releases will add more adapters, add support for GreenIT (manage
spare pools of resources). An integration with Sun's virtualization stacks
is planned.

We welcome the active evaluation, feedback and contribution of our 
to this project. See http://hedeby.sunsource.net for more information and
mailing lists for discussion.

2. New in Grid Engine "core" and Accounting and Reporting console (ARCo)
  - Scalability improvements - scale up to 63000 cores
     - improved qmaster-execd protocol
     - scheduler running as a thread in qmaster (faster communication
       between qmaster and scheduler threads)
     - improved resource matching in scheduler
     - faster qmaster startup
     - reduced memory requirements in big clusters
  - Advance Reservation (AR)
     - specified resources (e.g. machines, licenses) will be available 
for a
       guaranteed time window for specified users or user groups
  - New implementation of Interactive Job Support (IJS)
    - IJS is now natively implemented. No more need for external commands
      (rlogin, telnet, ssh)
  - Array Job Interdependencies
      - start task N of successor array job once predecessor array job task
        N has completed. Flexible definition of interdependencies possible
  - Multi cluster support for Accounting and Reporting Console (ARCo)
      - collect data of multiple Grid Engine clusters in a single
        (physical) database
      - do queries and get reports from single Web GUI from multiple ARCO
  - ARCo scalability improvements
      - improved dbwriter (component which writes Grid Engine reporting
        data into the database) speed
      - improved speed of queries
  - Improved ARCo installation experience
      - the documentation on ARCo installation has been significantly
  - Java Virtual Machine running as a thread in qmaster
      - A JVM thread providing a JMX server allows to contact qmaster
        natively from Java applications (the API is not yet officially
        supported). The SDM uses the new JMX interface.
  - Support for Solaris 10 startup scripts (SMF - Solaris Management 
  - Support for Sun Service Tags - inventory management through
    Sun Connected Services

C. Moving Grid Engine documentation set to http://wikis.sun.com
As one of the first products of Sun Microsystems the entire Grid Engine and
SDM documentation is provided in a wiki on http://wikis.sun.com.

By open sourcing Sun products, the closed and often slow way of providing
access to documentation to Sun customers and our communities is becoming
less adequate. With Grid Engine being one of Sun's first bigger products
which went open source, we are now taking the next step to modernize, ease
and speedup the access and contribution to our documentation set.

This enables quicker response to customer feedback (the Wiki provides a
feedback functionality which will be sent directly to the documentation
owners). The Wiki can be opened to interested users to allow directly
updating the content.
