Living In De-material World: On Microsoft and Bit Miles

I have written a fair bit here about Bit Miles (the moral imperative to digitise) and business process dematerialisation, so I was particularly interested in a recent trip to Microsoft’s gaming and world simulation division.

What was so relevant?

One area that I believe holds out great promise for this kind of simulation technology is in sustainable and sustainability modeling. Take the pilot training example above; while the highest cost may be for maintenance engineers, but how much fuel is being needlessly burned? Training in the real world is expensive. Moving Atoms has a cost. I have recently started talking about Bit Miles as a Greenmonk narrative, defined as is the carbon cost associated with moving a good or creating a service that could instead have been delivered digitally. Bit Miles offer us a moral imperative to digitize: a simulation of the world is a beautiful opportunity to rethink and potentially dematerialize business processes.

Why not Supply Chain Simulator ™, which would pull together all of your plant information (pulled in from OSI, say), where your people are located (Peoplesoft), and how you move goods and services (SAP) around the world? An organisation could begin to run really deep “What If” scenarios about the energy costs of their businesses with simulations like these. But what would really make these models sing is the fact they’d be visual and immersive. Telling is rarely as effective as Showing. What would a low energy manufacturing business look like? With virtual technology we could maybe work it out. At this point it might seem that I have gone off the deep end, but the ESP team inspires that in you. I didn’t see a single Powerpoint slide during my visit. Rather Shawn likes to open up people’s imaginations.

I would love to know your thoughts- there is a good discussion going on over at my monkchips blog.

Supercomputers can be Green - who knew?

According to Wikipedia most modern supercomputers are now highly-tuned computer clusters using commodity processors combined with custom interconnects.

The IBM Roadrunner supercomputer, for example, is a cluster of 3240 computers, each with 40 processing cores while NASA’s Columbia is a cluster of 20 machines, each with 512 processors.

If servers and data centers are considered the bad boys of the IT energy world, then supercomputers must be raving psychopaths, right? Well, not necessarily.

The findings of the Green500 List, an independent ranking of the most energy-efficient supercomputers in the world, show that this is far from the case. In fact in their June 2008 listings they report that:

The first sustained petaflop supercomputer – Roadrunner, from DOE Los Alamos National Laboratory – exhibits extraordinary energy efficiency.

Roadrunner, the top-ranked supercomputer in the TOP500, is ranked #3 on the Green500 List. This achievement further reinforces the fact that energy efficiency is as important as raw performance for modern supercomputers and that energy efficiency and performance can coexist.

Other interesting findings from the list are:

  1. The top three supercomputers surpass the 400 MFLOPS/watt milestone for the first time.
  2. Energy efficiency hits the mainstream - The energy efficiency of a commodity system based on Intel’s 45-nm low-power quad-core Xeon is now on par with IBM BlueGene/L (BG/L) machines, which debuted in November 2004 and
  3. Each of supercomputers in the top ten from this edition of the Green500 List has a higher FLOPS/watt rating than the previous #1 Green500 supercomputer (the previous list was 4 months ago in February)

IBM come out of this list as Big Green - out of the first 40 ranked systems, 39 are IBM-based. That is an incredible committment to Green which can’t be argued with and for which IBM deserves due credit.

And speaking of Green, it is great to see a supercomputer based in Ireland, the Irish Centre for High-End Computing’s Schrödinger supercomputer, coming in joint 4th place on the list of Green computers.

What makes this even more interesting is that many supercomputers are used in climate modelling and for research into Global Warming.

It is counterintuitive that supercomputers would be highly energy-efficient but it is precisely because they consume so much power that a lot of research is going into reducing supercomputers’ power requirements, thereby cutting their running costs. Once again a case of the convergence of ecology and economics (or green and greenbacks!).

Energy efficiency, demand response and smart grids all part of the solution

Hymn Sheet

The IEEE (the Institute of Electrical and Electronics Engineers), a non-profit organization, is the world’s leading professional association for the advancement of technology. The IEEE released a position paper on Energy Efficiency recently.

In the paper they make the case for the importance of energy efficiency policies and urge legislators to promote aggressive policies and legislation to nurture development of energy efficient products and services.

Through improved energy efficiency, the United States can grow the economy, improve balance of payments, strengthen national security, and mitigate the environmental impacts of energy use by reducing emission of both air pollutants that reduce air quality and impact public health, and greenhouse gases that affect climate change. Increased energy efficiency will help to decrease our vulnerability to oil supply disruptions.

Specifically make eight recommendations for the US federal government to implement:

  1. Promoting user awareness of economical energy efficiency opportunities
  2. Promulgating minimum efficiency standards for products consistent with life cycle
    analysis and internalization of environmental costs
  3. Providing incentives for capital investment in energy efficient technologies and processes
    in all sectors, such as residential, commercial, industrial and transportation
  4. Developing technologies to further reduce energy losses in electric power generation,
    transmission and distribution
  5. Developing, commercializing and using more efficient electric-drive technologies in
    public transit, freight, truck and personal transportation, such as plug-in hybrid electric
    vehicles
  6. Improving and upgrading transportation systems to reduce energy consumption, and
    adopting “smart growth” policies that reduce distances traveled
  7. Using communications and information technologies, such as teleconferencing and the
    Internet, to reduce the need for business travel, such as in telecommuting
  8. Using demand management programs to reduce peak demand, in lieu of building new
    generation.

Again we see reference to Demand Management and smart grid technologies. I had an analyst briefing with Cisco this morning and they too were referring to smart grids as were SAP yesterday.

When you see large commercial entities like SAP and Cisco and august non-profits like the IEEE and The Climate Group all singing off the same hymn sheet, about similar technologies to solve our energy problems you can be pretty confident that Demand Response and smart grid technologies are going to play a significant role in solving the energy crunch.

Nortel Energy Efficiency Calculator now online

Nortel Energy Efficiency Calculator

Nortel announced the release their Energy Efficiency Calculator online last week.

The tool is available for anyone to use after a quick registration (name, email and country) and uses best guestimates to give figures for energy spend.

The data are highly customisable, you can vary country, energy costs, company setup (network, no. of employees, etc.). It outputs costs to run the network infrastructure, kWh consumed, MBTUs generated and CO2 emissions.

This is an extension of the “Cisco Energy Tax” campaign which Nortel have been running very successfully now for some time.

It would be nice to see easy totals calculated for the outputs (possibly they are there but I didn’t see them) and it would be far nicer if it were not coded in Flash!

Having said that, this is a neat tool and reinforces the connection for companies between saving costs and lowering CO2 emissions.

Now Cisco, where is your rebuttal? ;-)
