"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 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.
"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 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.
An interview with IBM's Vice President of Open Source and Standards about their Open Source Strategy, the recent pledge of its patents for more than 150 open software standards, his take on the ODF vs. XML issue, and much more in The LXer Interview of Bob Sutor.
"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.
IBM has announced a version of its System i business server range that uses the company's Power6 processor, which the tech giant claims is the fastest chip it has ever built. The System i 570 uses the 4.7GHz Power6, launched in May, with up to 16 cores, a processor that has come top in many industry benchmarks.
While disk tuning is arguably less exciting than CPU or memory tuning, it is a crucial component in optimizing server performance. Learn more about direct I/O, concurrent I/O, asynchronous I/O, and best practices for each method of I/O implementation.
IBM has opened the AIX 6 beta program. "AIX 6 Open Beta participants will be able to download the AIX 6 beta code, Mozilla Firefox, and updates to enable previously purchased IBM compilers to run on AIX 6."
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.
"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 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'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.
"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 is not ready to guarantee that its computer programs are compatible with Oracle's recently launched version of the Linux operating system, an IBM spokesman said on Friday. This means that if IBM software programs turn out to be incompatible with Oracle Enterprise Linux, then it will be up to Oracle - and not IBM - to resolve the issue, said IBM spokesman Matthew McMahon.
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.
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.
"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.
Judging by details revealed in a chip conference agenda, the clock frequency race isn't over yet. IBM's Power6 processor will be able to exceed 5 gigahertz in a high-performance mode, and the second-generation Cell Broadband Engine processor from IBM, Sony and Toshiba will run at 6GHz, according to the program for the International Solid State Circuits Conference that begins February 11 in San Francisco.
IBM's Lotus Software division is taking a bigger bite of Apple's Mac OS X. The company on Dec. 28 formally rolled out the latest version of its Lotus messaging software package, dubbed Notes 7.0.2, which will include e-mail, calendar management tools and instant messaging that is specifically designed for Mac OS X users.
