Announcing Sun Grid Engine 6.2 Update 5
                                                               
==================================
                                                              
Regensburg, Germany -- December 22, 2009

We are announcing the availability of the Sun Grid Engine 6.2 Update 5
release. Sun Grid Engine 6.2u5 is a feature update release. We are
delivering cloud connectivity functionality, initial power saving
support, add a few much demanded features and complete the Microsoft
Vista support.

What's New
=========

Enhanced Inspect
-------------------------
Sun Grid Engine Inspect is a monitoring and configuration tool that
provides a flexible interface for viewing current and historical data
about your Sun Grid Engine cluster(s) and the Service Domain Manager.
Inspect now provides a new configuration wizard for the Sun Grid Engine
Parallel Environment and for the Service Domain Manger Cloud Service
(EC2) Adapter.

SDM Cloud Service Adapter supports multiple AWS EC2 machine images
--------------------------------------------------------------------------------------------------------
The Cloud Service Adapter provides the ability to expand the cluster
size to execute jobs on additional cloud hosts provided by the Amazon
Elastic Compute Cloud (EC2). It is now possible to extend the local
cluster with virtual nodes based on different Amazon EC2 AMIs.
Furthermore, the user feedback on the actions executed on the cloud
resources has been improved.

Support for Machine Readable Table Output in SDM
--------------------------------------------------------------------------
SDM command line commands now support a machine readable output format.
This simplifies and eases the integration of SDM and the use of sdmadm
commands in scripts. See Options for Formatting Table Output for further
information.

Slotwise Preemption
-----------------------------
The slotwise preemption allows to configure queue subordinate
relationships that affect only single slots and not whole queue
instances in the subordinated queues. Thus, the slotwise preemption
provides a means to ensure that high priority jobs get the resources
they need, while at the same time low priority jobs on the same host are
not unnecessarily preempted, maximizing the host utilization.

Apache Hadoop support
----------------------------------
This feature allows users to efficiently run Hadoop Map-Reduce jobs in a
SGE cluster. The SGE qmaster is made aware of HDFS data locality and of
the data needs of jobs and will schedule the Hadoop jobs accordingly.
After being assigned to a node by SGE, the actual processing of the job
is handed over to the Hadoop framework.

Topology-aware Scheduling (Job2Core Binding)
---------------------------------------------------------------------
Serial, threaded and parallel jobs can be bound to CPU sockets and cores
to achieve maximum application performance when running under SGE. The
new CLI submission parameter, "-binding", supports a range of binding
strategies. The CPU topology, numbers of sockets, cores and threads
available on a machine and used by jobs is reported as SGE load metrics.
This feature is available for Solaris 10 and OpenSolaris (x64, x86) and
Linux (x64, x86) operating systems which support the CPU core affinity
setting and reporting.

Job Submission Verifiers Java[TM] Language Binding (JJSV)
--------------------------------------------------------------------------------------
The server and client side job submission verifier (JSV) has been
enhanced to support JSVs written in the Java programming language.

Array Job Throttling
---------------------------
Array job throttling enables a user to set a self-imposed limit on the
maximum number of concurrently running tasks per job when submitting
jobs with the new "-tc" CLI submission option. This limit can be altered
for previously submitted jobs.

Licensing
-------------
For users without a Sun Grid Engine license, a 90 day evaluation use is
offered. The courtesy binaries based on the Grid Engine open source
project will be made available soon. They will continue to allow
unlimited use but will not include the Amazon EC2 and power saving
adapters, the SGE Inspect module or the Hadoop integration.
