Introduction to Realtime Linux Slides From SCALE 7x

I presented Introduction to Realtime Linux at SCALE 7x this past weekend.  The event was great, and our Red Hat and Fedora booths both received a lot of traffic--we ran out of almost all of our give-aways the first morning!

You can download the slides I presented here.

Upcoming Events: JBoss Virtual Experience and SCALE 2009

I'll be at a pair of events in the next couple weeks: the JBoss Virtual Experience and the Southern California Linux Expo (SCALE) 2009

At the JBoss Virtual Experience, I'll be manning a virtual booth to talk about Red Hat Enterprise MRG and Cloud Computing.  MRG Grid's support for virtualization and also integration with Amazon EC2 makes it a powerful tool for companies that either want to leverage the cloud or build their own cloud.  If you're attending the JBoss Virtual Experience, stop by the booth!

At SCALE, I'll be giving a talk, Introduction to Realtime Linux.    If you've wondered about Realtime Linux's benefits, performance characetristics, state, or just what it is, this will be a useful session to attend.  You can read about the rest of Red Hat and Fedora's presence at SCALE as well.

Red Hat Enterprise MRG 1.1 is Released

I'm pleased to announce that we released Red Hat Enterprise MRG 1.1 today.  This is a significant release that adds many new capabilities and performance enhancements.  It also introduces formal support around
the Grid component and entire MRG platform for the first time (Grid was Technology Preview in v1.0).  Some of the highlights of MRG 1.1 include:

  • Messaging
    • Native infiniband and RDMA driver for dramatically better
    • Active/Active Clustering
    • Enhanced security
    • Queue semantics like Last Value Queue and Ring Queue
    • Native .NET client
    • Improved management tools
    • Increased performance
  • Realtime
    • Improved performance, especially on boxes with higher CPU-counts
    • Improved performance tools. For example, Tuna now has the ability to write tunings to an init script once you've found an optimal tuning for your system
  • Grid
    • New GUI management tools
    • Low latency scheduling via MRG's messaging bus
    • Amazon EC2 support for adding capacity on-the-fly in the cloud
    • Concurrency limits on any scarce resource like software licenses or database handles
    • Dynamic provisioning, which enables you to mark slots as partitionable and sub-divide them dynamically so that more than one job can occupy a slot at once
