IBM Australia Chief Technologist podcast - Open systems, supercomputing, algorithms, research...

In this iTWire podcast, the Director of IBM Australia's Development Laboratory explains how it works on many different types of software and hardware projects, the IBM worldwide network of development and pure research labs, and gives his views on emerging technologies to watch.

Glenn Wightwick is an IBM Distinguished Engineer, Director of the IBM Australia Development Laboratory and IBM Australia Chief Technologist.Glenn Wightwick, irector of IBM Australia Development Laboratory .

He spoke with iTWire on a wide range of software and hardware technology issues, how IBM is addressing them across the globe, as well as the nature and scope of research and development work being carried out by the IBM Australia Lab.

Did you know that IBM Australia now has some 15,000 employees (it was less than 5,000 when I retired in the 1990s).

The IBM Australia Development Lab has locations spread right across Australia, with some 600 staff, which makes it one of the largest R&D organizations in the country. To put that into perspective, and picking just one other US-headed IT corporation with a notable presence here Down Under, I've been told that Microsoft Australia has something like 700 employees altogether.

I've often pondered IT multinationals and how they contribute to a particular nation, this being a topic for another blockbuster debate in its own right. Regarding the two corporations already mentioned, I've previously written a little on the matter, see: Which one is "bigger" -- Microsoft or IBM?

While it's certainly true that Microsoft currently has a lot of mind share, that's usually restricted to what I'd term "lighter" aspects of IT (such as desktop operating systems and office suites). They don't have the vast range of hardware, software, services and worldwide R&D of Big Blue.

Getting back to the IBM Australia Development Lab interview, we find that the Lab works directly with its clients on diverse software and hardware projects, such as security products in the IBM Tivoli area, web content management, Linux kernel work for the IBM Power microprocessor.

The Australian Lab — one of about 75 IBM labs across the globe — has locations right around the country, generally not working on products exclusively but as part of this global network. Projects are allocated based on skills and capabilities of the different teams.

For example, one of he the IBM web content management products is developed in Sydney, in close cooperation with the IBM labs in Beijing, Boeblingen (in Germany) and Raleigh (in North Carolina). And in Perth, there's a team of about 150 engineers working on mainframe software.

In Canberra, a team of about 25 engineers that all have deep expertise in the Linux kernel is working on microprocessors, including the Cell microprocessor (which can be found in the PlayStation 3 gaming console).


Glenn Wightwick discussed open standards, IBM's contributions (such as the Eclipse Project), and the reasons behind IBM's recent announcement of a new IT standards policy.

He preferred, however, to not say much about IBM's involvement with the attempted "hijacking of Linux" by SCO, and Microsoft's OOXML fight against ODF, since he thought there was already much written about these topics.

We discussed scientific computing (a.k.a. supercomputing), realt-time Linux and real-time Java, the Australian bid to host the Square Kilometre Array (a worldwide endeavour to build the world's largest radio telescope), and computing on a massive scale in general.

"We have well and truly moved beyond the environment of ten or fifteen years ago where transaction ruled and we measured systems only in terms of their transaction processing capability and throughput. ... Increasingly we are seeing enormous amounts of information arriving in real time events, that we refer to as stream computing, and what you're trying to do in those environments is make sense of very large amounts of information flowing in continuously.'

"You don't necessarily know what you're looking for. You might be seeing a whole bunch of data flowing in from wire services and across the Internet, financial information and so on."

"You might be looking for patterns and trends emerging that might enable you to understand particular trends and take decisions. There are some very interesting large computing problems in that space that we are beginning to take on as well."

Asked about the importance of the study of algorithms, Glenn Wightwick responded that algorithms are absolutely core to these sorts of problems, as important as they have ever been.

He described "System S" (exploratory Stream Processing Systems project at IBM's T.J. Watson Research Center) where the size and complexity of these problems demands that you understand how they'll perform.


The iTWire discussion with Glenn Wightwick moved on to the ever-increasing pace of technology change (twice as much processing power or disk space per dollar as you could get 18 months ago). In the disk drives areas, flash memory is starting to appear because solid state disk drives have about 100 times the random input/output performance of normal magnetic disk drives.

On the processor side, "it's really important to be able to understand the problems that you're solving and to be able to map that problem effectively through algorithms — in many cases, parallel algorithms — to exploit the multiple different processor cores that are available now on processors from IBM and other companies."

Glenn next described the locations of the various IBM labs around the globe where pure and applied research is carried out. "A lot of the research is oriented around trying to anticipate and drive the direction of the technologies that we might then implement if three or four or five years out, in our various different hardware and software products."

"Increasingly, we're using our research capabilities to help our clients. ... Our research team will bring their expertise in mathematical optimization, or whatever the case may be, to help the client solve what they considered to be an intractable problem. Our research organization  covers pretty much the entire spectrum, from fundamental research through to some really interesting applications areas as well."

The interview continued with with quantum computing and other coming technologies. One example is IBM's work on nanotechnology and around carbon nanotubes in particular.

We finished on the popular topic of the "eureka moment" and the process of turning fundamental research into useful products for IBM and its clients.

It's all about Webinars.

Marketing budgets are now focused on Webinars combined with Lead Generation.

If you wish to promote a Webinar we recommend at least a 3 to 4 week campaign prior to your event.

The iTWire campaign will include extensive adverts on our News Site and prominent Newsletter promotion and Promotional News & Editorial. Plus a video interview of the key speaker on iTWire TV which will be used in Promotional Posts on the iTWire Home Page.

Now we are coming out of Lockdown iTWire will be focussed to assisting with your webinatrs and campaigns and assassistance via part payments and extended terms, a Webinar Business Booster Pack and other supportive programs. We can also create your adverts and written content plus coordinate your video interview.

We look forward to discussing your campaign goals with you. Please click the button below.



iTWire TV offers a unique value to the Tech Sector by providing a range of video interviews, news, views and reviews, and also provides the opportunity for vendors to promote your company and your marketing messages.

We work with you to develop the message and conduct the interview or product review in a safe and collaborative way. Unlike other Tech YouTube channels, we create a story around your message and post that on the homepage of ITWire, linking to your message.
