Red Hat Makes Real-Time Linux Real

Red Hat's MRG product is essentially a variant of the core Red Hat
Enterprise Linux stack. Instead of supporting bread and butter
functions for database and applications serving like Enterprise Linux,
MRG is sculpted to best carry out messaging, real-time and grid
computing workloads.

The new 1.1 version of Enterprise MRG, originally due to ship by
December 31, is intended to replace the standard generic Linux kernel
with a real-time kernel based on the config_preempt_rt patch. That
patch that was jointly created by industry heavyweights Red Hat,
Novell, IBM, Silicon Graphics along with several smaller companies.

Breaking down the constituent parts of MRG, Red Hat officials note
that the R is relevant mostly to financial services companies and
defense contractors. The M is for those products, such as IBM's
Websphere MQ, that tend to pass a lot of messages between applications
and servers.

The G in MRG, until release 1.1, has been the missing link. Red Hat
officials said it has been the case largely because its programmers
have been working overtime to integrate the Condor grid into the
Enterprise MRG product. They said that when MRG went into beta in late
2007, the Condor technology was yet to be stitched in because it had
yet to support JBoss Enterprise stack.
