IBM Explores 67.1m-Core Computer for Running Entire Internet

"The Register has unearthed a research paper that shows IBM working on a computing system capable 'of hosting the entire internet as an application'. This mega system relies on a re-tooled version of IBM's Blue Gene supercomputers so loved by the high performance computing crowd. IBM's researchers have proposed tweaking the Blue Gene systems to run today's most popular web applications such as Linux, Apache, MySQL and Ruby on Rails."

IBM To Offer Office Software Free in Challenge to Microsoft’s Line

IBM plans to mount its most ambitious challenge in years to Microsoft's dominance of personal computer software, by offering free programs for word processing, spreadsheets and presentations. Steven A. Mills, senior vice president of IBM's software group, said the programs promote an open-source document format. The company is announcing the desktop software, called IBM Lotus Symphony, at an event today in New York. The programs will be available as free downloads from the IBM Web site.

Simplified Kernel Extensions with AIX Version 6

"Discover why you need to change your applications and build environments that supply 32-bit-only kernel extensions to accommodate IBM AIX Version 6. With AIX Version 6, the kernel environment is 64-bit kernel only. Previously, the AIX operating system provided both 32-bit and 64-bit kernels, requiring 32-bit and 64-bit kernel extensions. In this article, apply two easy solutions to help you make the transition and start reaping the benefits of the simplified kernel environment."

IBM Bolsters Security of Mainframe OS

IBM has introduced a release of its z/OS mainframe operating system with new features that increase the system's security for online commerce and business transactions. IBM officials said the new operating system release is in line with what the company has been calling the renaissance of the mainframe. And as mainframes run a vast portion of the world's financial services, retail and other large businesses, security was a major concern for this latest release, IBM officials said, in Armonk, N.Y.

IBM To Implement Sun Solaris on x86-Based System x

"IBM and Sun Microsystems did indeed announce an agreement for deploying the Solaris operating system on IBM servers, but it wasn't the system we guessed: IBM will deploy Solaris for its Intel x86-based System x and BladeCenter servers. It's a significant move, as it validates the presence of Sun's operating system among a broad customer base that few can mistake as a "niche." As Sun CEO Jonathan Schwartz told reporters today, IBM becomes the first Tier 1 reseller of Solaris products and services for x86 platforms." His blog is here.

Plan 9 Running on Blue Gene/L

A team comprised of members from Bell-Labs, IBM Research, Sandia National Labs, and Vita Nuova has completed a port of Plan 9 to the Blue Gene supercomputer. Plan 9 kernels are running on both the compute nodes and the I/O nodes and the Ethernet, Torus, Collective Network, Barrier Network, and Management network are all supported. Screenshots are available on the development blog, and a live-demo will be attempted during the USENIX poster session.

Developing a File System for AIX

"Learn the intricacies of the AIX file system framework. Every operating system provides a native kernel framework that kernel developers have to understand and adhere to when developing a piece of a kernel component for that operating system. This article sheds some light on the AIX file system framework. You need to understand the framework in order to develop a new file system, or to port an existing file system to the AIX operating system."

IBM Powers up Performance with Power6 Processor

IBM finally took the wraps off its much anticipated Power6 microprocessor, which company executives said will double the clock speed of its current Power5 chip, without stretching the power envelope. The Power6 processor, unveiled at an event on May 21 in London, is a dual-core chip with a top clock speed of 4.7GHz, double the 2.3GHz of the Power5+ processors. The new chip also includes 8MB of L2 cache - four times as large as the current Power5 offering - and an internal bandwidth of 300GB per second. Ars' John 'Hannibal' Stokes obviously also has his say.

IBM Preps Power6 by Putting AIX 5.3 on Life Support

IBM's Power6 push began this week with a tweak to AIX support. In a letter to customers, IBM vowed to support future updates to AIX 5.3 for an additional two years. This appears to be IBM's Power6 concession, since the vendor, according to our sources, will announce Power6 systems this month and ship them in the middle of the year but won't have AIX 5.4 available for months. Normally, IBM would like to have a new major release of AIX ready for its new processors and have customers upgrade accordingly. No such luck.

IBM Will Support x86 Linux Applications on System p Servers

"Today, IBM announced a public beta trial of a virtual Linux environment that will let x86 applications run on its System p Unix servers without modification. The new IBM System p Application Virtual Environment technology will allow x86 binaries to run as well without modification, removing the biggest barrier against effective virtualization for some companies. As a result, customers will be able to consolidate dozens, if not hundreds, of servers into one virtual environment."

IBM Plants Linux on the Desktop

IBM has announced an open-source desktop, running Lotus apps and Firefox on top of Red Hat or SUSE Linux. It's based on an internal project which has deployed Linux desktops to several thousand IBM staff, in what IBM said was one of the largest corporate Linux roll-outs to date. It added that its Open Client Solution can also take in Windows and Mac users, as there's Lotus software for those as well - although it admits that the Mac version of Notes 8 isn't due until later this year.

Branching Registers with the PowerPC Processor

In Part 1 of this series you saw how programs on the POWER5 processor work using the 64-bit PowerPC instruction set, then in Part 2 you learned how the PowerPC instruction set addresses memory, and how to do position-independent code. In this article, you learn how to use the very powerful condition and branch instructions available in the PowerPC instruction set.

How Big Blue Became Linux’s Best Friend

"When open-source developers and IBM took gambles on each other, free software showed it can flourish in the heartland of corporate computing." This is chapter 7 (free sample, so to speak) of a book on Linux and free software's rise to fame and use in the corporate world.
