Porting from IRIX to Linux
Right now you can drive, shoot the weapons and interact with DIS entities in Paradigm's Atlantis database (credit goes to John Powers and Lori Shearer for helping with the CTDB files). The system can talk to VAPS panels running on another host under Windows NT (credit goes to Kay Chao, Kathy Jones and Vince Golubic).
Much has changed since this work was done (first quarter 2000). ACRT can now use the newer High Level Architecture (HLA), a successor to DIS. SGI is continuing to make contributions to the world of Linux, including releasing the reference implementation of OpenGL. A new version of Mongoose is out, and we're experimenting with it now. By the time you read this, version 2.4 should be out, unifying IRIX and Linux distributions. nVidia has come out with new graphics cards and Linux drivers. The long-awaited XFree86 version 4 is out with direct rendering of OpenGL. (Prior versions took a performance hit when they had to first render to X and then to the screen.) Motif is now free on Linux systems.
A Linux version of the VAPS tool we used for soft panels is due out in first quarter of 2001.

Practical Task Scheduling Deployment
One of the best things about the UNIX environment (aside from being stable and efficient) is the vast array of software tools available to help you do your job. Traditionally, a UNIX tool does only one thing, but does that one thing very well. For example, grep is very easy to use and can search vast amounts of data quickly. The find tool can find a particular file or files based on all kinds of criteria. It's pretty easy to string these tools together to build even more powerful tools, such as a tool that finds all of the .log files in the /home directory and searches each one for a particular entry. This erector-set mentality allows UNIX system administrators to seem to always have the right tool for the job.
Cron traditionally has been considered another such a tool for job scheduling, but is it enough? This webinar considers that very question. The first part builds on a previous Geek Guide, Beyond Cron, and briefly describes how to know when it might be time to consider upgrading your job scheduling infrastructure. The second part presents an actual planning and implementation framework.

With all the industry talk about the benefits of Linux on Power and all the performance advantages offered by its open architecture, you may be considering a move in that direction. If you are thinking about analytics, big data and cloud computing, you would be right to evaluate Power. The idea of using commodity x86 hardware and replacing it every three years is an outdated cost model. It doesn’t consider the total cost of ownership, and it doesn’t consider the advantage of real processing power, high-availability and multithreading like a demon.
This ebook takes a look at some of the practical applications of the Linux on Power platform and ways you might bring all the performance power of this open architecture to bear for your organization. There are no smoke and mirrors here—just hard, cold, empirical evidence provided by independent sources. I also consider some innovative ways Linux on Power will be used in the future.Get the Guide
