            Grid Engine 6.2 and SDM 1.0u1 Courtesy Binaries now 
Available for Download
                            Regensburg, Germany -- September 23, 2008

After releaseing the Sun Grid Engine 6.2 software by Sun Microsystems on 
August 5, 2008, the open source Grid Engine 6.2 and SDM 1.0u1 courtesy 
binaries are now available 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 Service Domain Manager (SDM), aka. project Hedeby allows to 
dynamically (re-)assign computational resources on demand.
The courtesy binaries are available at


The courtesy binary distribution is now hosted on Sun Microsystems 
servers on Sun Download Center (SDLC).

The corresponding source code tag in the CVS repository has the name
         V62_TAG (Grid Engine and ARCo) and V10_U1_TAG (Service Domain 

A snapshot of the sources is available at the Documents & Files page

What's new in Grid Engine 6.2

   1. Service Domain Manager
   2. New in Grid Engine "core" and Accounting and Reporting Console (ARCo)

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 
clusters. 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 
community to this project. See http://hedeby.sunsource.net for more 
information and mailing lists for discussion.
New in Grid Engine "core" and Accounting and Reporting console (ARCo)

    * Scalability improvements - scale up to 63000 cores
          o improved qmaster-execd protocol
          o scheduler running as a thread in qmaster (faster 
communication between qmaster and scheduler threads)
          o improved resource matching in scheduler
          o faster qmaster startup
          o reduced memory requirements in big clusters
    * Advance Reservation (AR)
          o 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)
          o IJS is now natively implemented. No more need for external 
commands (rlogin, telnet, ssh)
    * Array Job Interdependencies
          o 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)
          o collect data of multiple Grid Engine clusters in a single 
(physical) database
          o do queries and get reports from single Web GUI from multiple 
ARCO databases
    * ARCo scalability improvements
          o improved dbwriter (component which writes Grid Engine 
reporting data into the database) speed
          o improved speed of queries
    * Improved ARCo installation experience
          o the documentation on ARCo installation has been 
significantly improved
    * Java Virtual Machine running as a thread in qmaster
          o 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
