An Interview with DEC

David Rusling and Jon “maddog” Hall talk about Digital Equipment Corporation and the porting of Linux to the 64-bit Alpha.

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.

David Rusling:

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.

Linux Management with Red Hat Satellite: Measuring Business Impact and ROI

Linux has become a key foundation for supporting today's rapidly growing IT environments. Linux is being used to deploy business applications and databases, trading on its reputation as a low-cost operating environment. For many IT organizations, Linux is a mainstay for deploying Web servers and has evolved from handling basic file, print, and utility workloads to running mission-critical applications and databases, physically, virtually, and in the cloud. As Linux grows in importance in terms of value to the business, managing Linux environments to high standards of service quality — availability, security, and performance — becomes an essential requirement for business success.

White Paper
Private PaaS for the Agile Enterprise

If you already use virtualized infrastructure, you are well on your way to leveraging the power of the cloud. Virtualization offers the promise of limitless resources, but how do you manage that scalability when your DevOps team doesn’t scale? In today’s hypercompetitive markets, fast results can make a difference between leading the pack vs. obsolescence. Organizations need more benefits from cloud computing than just raw resources. They need agility, flexibility, convenience, ROI, and control.

Stackato private Platform-as-a-Service technology from ActiveState extends your private cloud infrastructure by creating a private PaaS to provide on-demand availability, flexibility, control, and ultimately, faster time-to-market for your enterprise.
