Foraging for Resources in the Multicore Present and Future

HPC consultant Wolfgang Gentzsch has thoughtfully updated the case of multicore architectures in the HPC context. Over on LinkedIn, via one of the HPC discussion groups, I responded with:

I also enjoyed your article, Wolfgang – thank you. Notwithstanding the drive towards cluster-on-a-chip architectures, HPC customers will require workload managers (WLMs) that interface effectively and efficiently with O/S-level features/functionalities (e.g., MCOPt Multicore Manager from eXludus for Linux, to re-state your example). To me, this is a need well evidenced in the past: For example, various WLMs were tightly integrated with IRIX’s cpuset functionality (http://www.sgi.com/products/software/irix/releases/irix658.html) to allow for topology-aware scheduling in this NUMA-based offering from SGI. In present and future multicore contexts, the appetite for petascale and exascale computing will drive the need for such WLM-O/S integrations. In addition to the multicore paradigm, what makes ‘this’ future particularly interesting, is that some of these multicore architectures will exist in a hybrid (CPU/GPU) cloud – a cloud that may compliment in-house resources via some bursting capability (e.g., Bright’s cloud bursting, http://www.brightcomputing.com/Linux-Cluster-Cloud-Bursting.php). As you also well indicated in your article, it is incumbent upon all stakeholders to ensure that this future is a friendly as possible (e.g., for developers and users). To update a phrase originally spun by Herb Sutter (http://www.gotw.ca/publications/concurrency-ddj.htm) in the multicore context, not only is the free lunch over, its getting tougher to find and ingest lunches you’re willing to pay for!

We certainly live in interesting times!

Early Win Required for Partner-Friendly, Post-Acquisition Platform Computing

Further to the LinkedIn discussion on the relatively recent acquisition of Platfom by IBM, I just posted:

Platform CEO and Founder Songnian Zhou has this to say regarding the kernel of this discussion:

“IBM expects Platform to operate as a coherent business unit within its Systems and Technology Group. We got some promises from folks at IBM. We will accelerate our investments and growth. We will deliver on our product roadmaps. We will continue to provide our industry-best support and services. We will work even harder to add value to our partners, including IBM’s competitors. We want to make new friends while keeping the old, for one is silver while the other is gold. We might even get to keep our brand name. After all, distributed computing needs a platform, and there is only one Platform Computing. We are an optimistic bunch. We want to deliver to you the best of both worlds – you know what I mean. Give us a chance to show you what we can do for you tomorrow. Our customers and partners have journeyed with Platform all these years and have not regretted it. We are grateful to them eternally.”

Unsurprisingly upbeat, Zhou, Platform and IBM, really do require that customers and partners give them a chance to prove themselves under the new business arrangement. As noted in my previous comment in this discussion, this’ll require some seriously skillful stickhandling to skirt around challenging issues such as IP (Intellectual Property) – a challenge that is particularly exacerbated by the demands of the tightly coupled integrations required to deliver tangible value in the HPC context.

How might IBM-acquired Platform best demonstrate that it’s true to its collective word:

“Give us a chance to show you what we can do for you tomorrow.”

Certainly one way, is to strike an early win with a partner that demonstrates that they (Zhou, Platform and IBM) are true to their collective word. Aspects of this demonstration should likely include:

  • IP handling disclosures. Post-acquisition Platform and the partner should be as forthcoming as possible with respect to IP (Intellectual Property) handling – i.e., they should collectively communicate how business and technical IP challenges were handled in practice.
  • Customer validation. Self-explicit, such a demonstration has negligible value without validation by a customer willing to publicly state why they are willing to adopt the corresponding solution.
  • HPC depth. This demonstration has to be comprised of a whole lot more than merely porting a Platform product to a partner’s platform that would be traditionally viewed as a competitive to IBM. As stated previously, herein lies the conundrum: “To deliver a value-rich solution in the HPC context, Platform has to work (extremely) closely with the ‘system vendor’.  In many cases, this closeness requires that Intellectual Property (IP) of a technical and/or business nature be communicated …”

Thus, as the fullness of time shifts to post-acquisition Platform, trust becomes the watchword for continued success – particularly in HPC.

For without trust, there will be no opportunity for demonstrations such as the early win outlined here.

How else might Platform-acquired IBM demonstrate that it’s business-better-than-usual?

RTM for Android: Significant Update Indeed!

I just upgraded to the latest, native-client release of RTM (Remember the Milk) for my Motorola Xoom tablet.

As expressed by the RTM team, this is a  very significant update. Although the details of the update are well covered over on the RTM blog, in 5 minutes of usage I’m left with the impression of:

  • A much improved user interface
  • A much more deeply integrated application

Although I’ve flirted with other tools/utilities for task management (including Evernote!), I’ve always returned to, or remained with, RTM. This latest update for the Android platform gives me another reason not to bother looking elsewhere.

Kudos to Bob T. Monkey and the rest of the banana-loving team down under at RTM!

IBM-Acquired Platform: Plan for Sustained, Partner-Friendly HPC Innovation Required

Over on LinkedIn, there’s an interesting discussion taking place in the “High Performance & Super Computing” group on the recently announced acquisition of Markham-based Platform Computing by IBM. My comment (below) was stimulated by concerns regarding the implications of this acquisition for IBM’s traditional competitors (i.e., other system vendors such as Cray, Dell, HP, etc.):

It could be argued:

“IBM groks vendor-neutral software and services (e.g., IBM Global Services), and therefore coopetition.”

At face value then, it’ll be business-as-usual for IBM-acquired Platform – and therefore its pre-acquisition partners and customers.

While business-as-usual plausibly applies to porting Platform products to offerings from IBM’s traditional competitors, I believe the sensitivity to the new business relationship (Platform as an IBM business unit) escalates rapidly for any solution that has value in HPC.

Why?

To deliver a value-rich solution in the HPC context, Platform has to work (extremely) closely with the ‘system vendor’. In many cases, this closeness requires that Intellectual Property (IP) of a technical and/or business nature be communicated – often well before solutions are introduced to the marketplace and made available for purchase. Thus Platform’s new status as an IBM entity, has the potential to seriously complicate matters regarding risk, trust, etc., relating to the exchange of IP.

Although it’s been stated elsewhere that IBM will allow Platform measures of post-acquisition independence, I doubt that this’ll provide sufficient comfort for matters relating to IP. While NDAs specific to the new (and independent) Platform business unit within IBM may offer some measure of additional comfort, I believe that technically oriented approaches offer the greatest promise for mitigating concerns relating to risk, trust, etc., in the exchange of IP.

In principle, one possibility is the adoption of open standards by all stakeholders. Such standards hold the promise of allowing for the integration between products via documented interfaces and protocols, while allowing (proprietary) implementation specifics to remain opaque. Although this may sound appealing, the availability of such standards remains elusive – despite various, well-intended efforts (by HPC, Grid, Cloud, etc., communities).

While Platform’s traditional competitors predictably and understandably gorge themselves sharing FUD, it obviously behooves both Platform and IBM to expend some effort allaying the concerns of their customers and partner ecosystem.

I’d be interested to hear of others’ suggestions as to how this new business relationship might allow for sustained innovation in the HPC context from IBM-acquired Platform.

Disclaimer: Although I do not have a vested financial interest in this acquisition, I did work for Platform from 1998-2005.

To reiterate here then:

How can this new business relationship allow for sustained, partner-friendly innovation in the HPC context from IBM-acquired Platform?

Please feel free to share your thoughts on this via comments to this post.

Remembering Steve Jobs

I was doing some errands earlier this evening (Toronto time) … While I was in the car, the all-news station (680news) I had on played some of Steve Jobs’ 2005 commencement address to Stanford grads. As I listened, and later re-read my own blog post on discovering the same address, I’m struck on the event of his passing by the importance of valuing every experience in life. In Jobs’ case, he eventually leveraged his experience with calligraphy to design the typography for the Apple Mac – after a ten-year incubation period!

I think it’s time to read that Stanford commencement address again …

RIP Steve – and thanks much.

Aakash: A Disruptive Innovation in the Truest Sense

Much has been, and will be, written about the Aakash tablet.

[With apologies for the situational monsoonal imagery ...] As I awash myself in Aakash, I am particularly taken by:

  • The order of magnitude reduction in price point. With a stated cost of about $50, marked-up prices are still close to an order of magnitude more affordable than the incumbent offerings (e.g., the iPad, Android-based tablets, etc.). Even Amazon’s Kindle Fire is 2-3 times more expensive.
  • The adoption of Android as the innovation platform. I take this as yet another data point (YADP) in firmly establishing Android as the leading future proofed platform for innovation in the mobile-computing space. As Aakash solidly demonstrates, it’s about the all-inclusive collaboration that can occur when organizational boundaries are made redundant through use of an open platform for innovation. These dynamics just aren’t the same as those that would be achieved by embracing proprietary platforms (e.g., Apple’s iOS, RIM QNX-based O/S, etc.).
  • The Indian origin. It took MIT Being Digital, in the meatspace personage of Nicholas Negroponte, to hatch the One Laptop Per Child initiative. In the case of Aakash, this is grass-roots innovation that has Grameen Bank like possibilities.
While some get distracted comparing/contrasting tech specs, the significant impact of Aakash is that it is a disruptive innovation in the truest sense:
“An innovation that is disruptive allows a whole new population of consumers access to a product or service that was historically only accessible to consumers with a lot of money or a lot of skill.  Characteristics of disruptive businesses, at least in their initial stages, can include:  lower gross margins, smaller target markets, and simpler products and services that may not appear as attractive as existing solutions when compared against traditional performance metrics.”
I am certainly looking forward to seeing this evolve!

Disclaimers:
  • Like Aakash, I am of Indian origin. My Indian origin, however, is somewhat diluted by some English origin – making me an Anglo-Indian. Regardless, my own origin may play some role in my gushing exuberance for Aakash – and hence the need for this disclaimer.
  • I am the owner of a Motorola Xoom, but not an iPad. This may mean I am somewhat predisposed towards the Android platform.
Feel free to chime in with your thoughts on Aakash by commenting on this post.

Targeting Public Speaking Skills via Virtual Environments

Recently I shared an a-ha! moment on the use of virtual environments for confronting the fear of public speaking.

The more I think about it, the more I’m inclined to claim that the real value of such technology is in targeted skills development.

Once again, I’ll use myself as an example here to make my point.

If I think back to my earliest attempts at public speaking as a graduate student, I’d claim that I did a reasonable job of delivering my presentation. And given that the content of my presentation was likely vetted with my research peers (fellow graduate students) and supervisor ahead of time, this left me with a targeted opportunity for improvement: The Q&A session.

Countless times I can recall having a brilliant answer to a question long after my presentation was finished – e.g., on my way home from the event. Not very useful … and exceedingly frustrating.

I would also assert that this lag, between question and appropriate answer, had a whole lot less to do with my expertise in a particular discipline, and a whole lot more to do with my degree nervousness – how else can I explain the ability to fashion perfect answers on the way home!

image006Over time, I like to think that I’ve approved my ability to deliver better-quality answers in real time. How have I improved? Experience. I would credit my experience teaching science to non-scientists at York, as well as my public-sector experience as a vendor representative at industry events, as particularly edifying in this regard.

Rather than submit to such baptisms of fire, and because hindsight is 20/20, I would’ve definitely appreciated the opportunity to develop my Q&A skills in virtual environments such as Nortel web.alive. Why? Such environments can easily facilitate the focused effort I required to target the development of my Q&A skills. And, of course, as my skills improve, so can the challenges brought to bear via the virtual environment.

All speculation at this point … Reasonable speculation that needs to be validated …

If you were to embrace such a virtual environment for the development of your public-speaking skills, which skills would you target? And how might you make use of the virtual environment to do so?

Confronting the Fear of Public Speaking via Virtual Environments

Confession: In the past, I’ve been extremely quick to dismiss the value of Second Life in the context of teaching and learning.

Even worse, my dismissal was not fact-based … and, if truth be told, I’ve gone out of my way to avoid opportunities to ‘gather the facts’ by attending presentations at conferences, conducting my own research online, speaking with my colleagues, etc.

So I, dear reader, am as surprised as any of you to have had an egg-on-my-face epiphany this morning …

Please allow me to elaborate:

It was at some point during this morning’s brainstorming session that the egg hit me squarely in the face:

Why not use Nortel web.alive to prepare graduate students for presenting their research?

Often feared more than death and taxes, public speaking is an essential aspect of academic research – regardless of the discipline.

image004Enter Nortel web.alive with its virtual environment of a large lecture hall – complete with a podium, projection screen for sharing slides, and most importantly an audience!

As a former graduate student, I could easily ‘see’ myself in this environment with increasingly realistic audiences comprised of friends, family and/or pets, fellow graduate students, my research supervisor, my supervisory committee, etc. Because Nortel web.alive only requires a Web browser, my audience isn’t geographically constrained. This geographical freedom is important as it allows for participation – e.g., between graduate students at York in Toronto and their supervisor who just happens to be on sabbatical in the UK. (Trust me, this happens!)

As the manager of Network Operations at York, I’m always keen to encourage novel use of our campus network. The public-speaking use case I’ve described here has the potential to make innovative use of our campus network, regional network (GTAnet), provincial network (ORION), and even national network (CANARIE) that would ultimately allow for global connectivity.

While I busy myself scraping the egg off my face, please chime in with your feedback. Does this sound useful? Are you aware of other efforts to use virtual environments to confront the fear of public speaking? Are there related applications that come to mind for you? (As someone who’s taught classes of about 300 students in large lecture halls, a little bit of a priori experimentation in a virtual environment would’ve been greatly appreciated!)

Update (November 13, 2009): I just Google’d the title of this article and came up with a few, relevant hits; further research is required.
