Red Hat Enterprise MRG (Messaging, Realtime, and Grid) is a
next-generation IT infrastructure for enterprise computing. MRG 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.
Multiple format string flaws were found in Condor. An authenticated
Condor service user could use these flaws to prevent other jobs from
being scheduled and executed, crash the condor_schedd daemon, or,
possibly, execute arbitrary code with the privileges of the 'condor'
These updated packages for Red Hat Enterprise Linux 5 provide
enhancements and bug fixes for the Grid component of MRG. Some select
enhancements and fixes include :
* Addition of -sort option to condor_status
* Customized output from condor_q -run for EC2 jobs
* Enhanced the summary line provided by condor_q
* Improved Collector performance around blocking network calls
* Fixed a memory leak associated with python-psycopg2 hit by
