Red Hat Enterprise Linux 5.2 Beta Released

Posted on in Categories Linux, Linux distribution, News, RedHat/Fedora Linux last updated March 14, 2008

RHEL 5.2 beta has been released. Red Hat engineers backport many of the new features from later kernels to the Red Hat Enterprise Linux 5 kernel, such as support for new hardware and virtualization enhancements. This provides Red Hat Enterprise Linux subscribers with important new capabilities while maintaining stable application interfaces — so that applications continue to run after new updates are installed. And, of course, it’s always worth repeating that updates, which are released about twice a year, are included with every Red Hat Enterprise Linux subscription.

This will give our you a chance to see what your systems will be running later this year. You can grab beta version from RHN.

The new Linux scheduler extends scheduling capabilities by introducing scheduling classes and also simplifies debugging by improving schedule statistics. Completely Fair Scheduler (CFS) is getting good reviews when tested for thread-intensive applications including 3D games. CFS handles CPU resource allocation for executing processes, and aims to maximize overall CPU utilization while maximizing interactive performance. CFS considered as the first implementation of a fair queuing process scheduler in a widely used general-purpose operating system.

The Linux 2.6.23 kernel comes with a modular scheduler core and a CFS, which is implemented as a scheduling module. In this article, get acquainted with the major features of the CFS, see how it works, and look ahead to some of the expected changes for the 2.6.24 release.
