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 ( 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, 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 ( 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?

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.


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?

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.

Multi-Touch Computational Steering

About 1:35 into

Jeff Han impressively demonstrates a lava-lamp application on a multi-touch user interface.

Having spent considerable time in the past pondering the fluid dynamics (e.g., convection) of the Earth’s atmosphere and deep interior (i.e., mantle and core), Han’s demonstration immediately triggered a scientific use case: Is it possible to computationally steer scientific simulations via multi-touch user interfaces?

A quick search via Google returns almost 20,000 hits … In other words, I’m likely not the first to make this connection 😦

In my copious spare time, I plan to investigate further …

Also of note is how this connection was made: A friend sent me a link to an article on Apple’s anticipated tablet product. Since so much of the anticipation of the Apple offering relates to the user interface, it’s not surprising that reference was made to Jeff Han’s TED talk (the video above). Cool.

If you have any thoughts to share on multi-touch computational steering, please feel free to chime in.

One more thought … I would imagine that the gaming industry would be quite interested in such a capability – if it isn’t already!
