Hoping to counterpunch archrival Novell in the real-time Linux market, Red Hat has shipped the second release of its Enterprise MRG Real-Time Linux.
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.
