An Interview with DEC
We could use some more tuning of the compiler optimization sequences which the gcc compilers generate for the super-scalar Alpha architecture. Likewise, certain math libraries need to be optimized and made available in source code format, not only for the Alpha, but for other ports as well.
We would like to see a virtual porting and certification lab on the Internet, so applications developers who do not have Alpha systems can port and test their applications. This would also be a good idea for some of the other ports, such as SunSPARC, PowerPC, etc.
Testing and benchmarking of Alpha systems running Linux under different load types, creating meaningful benchmark results would also be useful.
Doing real work in large-scale distributed computing with “clusters” of Linux systems would also provide helpful information.
Also needed is a defined set of applications program interfaces (APIs) and application binary interfaces (ABIs) that fit across a variety of Alpha Unix and Linux systems (FreeBSD, netBSD, Linux, Digital UNIX and a variety of other Unix systems) so that commercial application vendors could create shrink-wrapped applications for a larger audience than any one Unix system could attract. Applications tested against the ABI should be able to run on any Alpha Unix/Linux system.
I agree. The future of Linux (all flavours) rests on its ability to attract applications. Whilst the normal engineering set of tools (Emacs, LaTeX, Tk and so on) works quite happily on all of the Linux platforms, Linux needs more of the marketing and presentation tools. It needs a viable desktop environment. That can either be the ability to run Windows applications via Wabi or it can be native applications conforming to some interface specification. The free software world is unfortunately less interested in WYSIWYG applications than in writing operating systems.
One option I find really attractive is the idea that Java applications could run under Linux as well as, if not better than, any other operating system incorporating a Java Machine.
While Digital has allocated four engineers, one product manager and one very over-worked marketing manager to the task, we realize none of this could be possible without the long hours contributed by the Linux community.
We want to help the community move Linux along the path that they feel is the best.

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
