RHEA-2011:0889 - Product Enhancement Advisory

Topic

Red Hat Enterprise MRG Grid 2.0 packages that include a number of bug fixes and
enhancements are now available for Red Hat Enterprise Linux 5.

Description

Red Hat Enterprise MRG is a next-generation IT infrastructure incorporating
Messaging, Realtime, and Grid functionality. It offers increased performance,
reliability, interoperability, and faster computing for enterprise customers.

MRG Grid provides high-throughput computing and enables enterprises to achieve
higher peak computing capacity as well as improved infrastructure utilization by
leveraging their existing technology to build high performance grids. MRG Grid
provides a job-queueing mechanism, scheduling policy, and a priority scheme, as
well as resource monitoring and resource management. Users submit their jobs to
MRG Grid, where they are placed into a queue. MRG Grid then chooses when and
where to run the jobs based upon a policy, carefully monitors their progress,
and ultimately informs the user upon completion.

These updated packages for Red Hat Enterprise Linux 5 provide numerous bug fixes
and enhancements for the Grid component of MRG. Some of the most important
enhancements include:

• Integrated configuration and management experience, including real-time

monitoring, diagnostics, and configuration templates.

• Advanced scheduling.
• APIs for ISV application integration.
• Expanded scale and performance.
• Power management.

Space precludes documenting all of these changes in this advisory. Users are
directed to the Red Hat Enterprise MRG 2 Technical Notes document for
information on the most significant of these changes:

Users of the Grid capabilities of Red Hat Enterprise MRG 2.0, which is layered
on Red Hat Enterprise Linux 5, are advised to upgrade to these updated packages,
which provide numerous bug fixes and enhancements.
