Real Time Linux Now Reality
Red Hat, Inc. has launched a real-time version of Linux, aimed at applications needing predictable responses, from process control to financial market traders.
Red Hat Enterprise MRG (Messaging, Realtime, Grid) includes features such as high-speed inter-application messaging based on the Advanced Message Queuing Protocol (AMQP), whose performance Red Hat reckoned it had improved 100-fold. At the U.K. launch, Red Hat VP Scott Crenshaw could not explain how this was achieved. Other representatives said that details will be available on the company’s blog.
MRG also allows customers to “steal” unused desktop CPU cycles, to manage distributed workloads, to schedule tasks across both local and remote grids and to use cloud capacity from Amazon EC2. The distributed computing capabilities originated from Red Hat’s collaboration with the University of Wisconsin and its high-throughput computing project, Condor. The code for this portion of the system is open source under an OSI-approved license.
