How many FLOPS?
FLoating point Operations Per Second – FLOPS, one of the more obscure acronyms in our lives, and one of the oldest ones. It’s since been modified with a prefix of M (mega), G (giga) and most recently T (tera). A Terra is a million millions, one trillion (1012) a whole lot of anything, whether its cycles (Hertz), Bytes, dollars, or FLOPS. (And note - the ‘S’ in FLOPS is capitalized.)
So I was asked recently, how many TFLOPS in all the game consoles?
There are two answers to that question.
Do you mean in all the ones built, or just the FLOPS of the specific consoles?
So what is the TFLOPS rating of the game consoles? Well there are two answers to that question too.
If you count central processor FLOPS that’s one answer, if you count the FLOPS potential of the GPU and add it to the CPU’s FLOPS that’s another answer. And that answer provokes all kinds of debate. One side (the one I favor) is that the FLOPS of the GPU aren’t used in computations and therefore shouldn’t be counted because they can’t be measured and just represent a theoretical number. The other side argues that they are indeed being used in computation - the computation of shader operations. However, both sides agree that there isn’t yet a benchmark that can measure them. And therefore I conclude that we shouldn’t use them in evaluating the CPU FLOPS of game consoles.
The other main answer to the original question is do you mean in all the ones built, so I added in the installed base of all the consoles shipped.
The following table lists the FLOPS in consoles.

2007, October: Sony PS3 console, at US$400, that runs at a claimed 2 teraFLOPS; these figures represent the processing power of the GPU. The seven CPUs run collectively at a lower 218 GFLOPS.[14]
All of the GLOPS of all the consoles to date are only 402; where as a modern GPU is over two times that – Moore’s law in action.
You can read this several ways:
- All of the CPU consoles added up don’t equal 1 TFLOPS.
- All of the consoles added up don’t exceed 2 TFLOPS even if you count GPU and CPU.
- All consoles shipped to date add up to 7.318 EFLOPS - Exa FLOPS - 1018 and that’s a number that that thrills the folks at
.
Now why did I go through this laborious, pedantic, and sure to be arguable discussion? For several reasons:
- It’s raining here on Mt Tiburon so I can’t go out and play.
- I thought it was really interesting to look at how far consoles have progressed
- I thought it was even more interesting to look at how far PC graphics have progressed – ATI and Nvidia are shipping TFLOPS AIBs, and the next gen coming out in June, with Dual GPUs will be approaching 5 TFLOPS per AIB.
Just think of what the game developers and the movie studios can do with kind of horsepower.
Think of the shader operations that will be offered soon. Those of you reading this who know me know Peddie’s first law – in computer graphics too much is not enough. And although I haven’t made it a law yet, if I did (it would be number three), I’m fond of saying – don’t just watch a movie – be in the movie.
That’s where we’re heading with all these tera and peta FLOPS and I can’t wait to get there because next stop after this one is the holodeck.

Moore’s law violated by inflation – your new laptop will cost more
Another contributor to sluggish PC sales for this year
Even though one of the applied tenants of Moore’s law is that prices will drop over time (Moore never said that, it’s just a statement that has been applied to his original observation about feature size shrinkage over time), it appears the rising price of oil will change that as nations around the world grapple with inflation. Prices will rise.
This appears to be showing up first in laptop costs as reports of higher priced magnesium-aluminum alloy chassis are coming out of China with cost increases of 10% due to rising metal costs caused by the increasing cost of extracting, processing, and delivering those metals thanks to the higher price of oil. And although some notebook vendors are looking at using plastics, that won’t help given that plastic is made from oil.
Other costs are increasing as well and Acer, HP, and Levovo had indicated their ODMs are raising prices by as $5 to $20. Compal and Wistron the world’s three largest contract manufacturers have reported they will be raising prices for the first time.
At the same time Hynix Semiconductor, the world’s No. 2 memory chip maker raised contract prices for computer memory chips by about 15 percent last month and expected further increases in May although some expect DRAM prices to start falling again in the fourth quarter; this may be wishful thinking.
Desktop PCs won’t escape these cost increases and if personal and corporate incomes don’t increase accordingly then the inflationary increases in PCs could have a dampening effect on already sluggish sales.

Come together ... over me
Common people now, smile on your brother, everybody get together, try to love one another - for a while…
We’re getting closer to the dream, the vision, of ubiquity mutual connectivity in the home – and maybe beyond a bit.
My vision, since 1999, has been that everything in the home will talk to everything in the home. Everything that can will be a server, and everything will be a client. Since 1999 I’ve had to modify my vision a bit, I’ve had to learn a strange new alphabet, B, A, C, U, and then N – what’s that all about? And I had to add handheld devices to the mix. But basically the dream is alive and getting closer everyday.
Some folks thought (including me for a while) that we would have a master server in our homes, a data furnace if you will. But it soon became apparent that storage was becoming cheaper and moving in a curve steeper than Moore’s law. We also saw the explosion and proliferation of non-volatile memory in most machines and our pockets. And we saw the ever expanding, and ever faster, proliferation of network technology.
Today’s media addict has at least one, and probably three handheld devices that he or she users as a player and also as a recorder or a storage device – an MP3 player, a mobile phone, and maybe a dedicated media player. All of them have a combination of tunes, photos, and videos on them. Stationary devices like STBs with HDDs, DVD players, PCs, and TVs have similar types of media either stored or streaming to through them; and semi-mobile devices like laptops do too.
We have all kinds of alphabet laws and rules to get these things talking to each other DNLA, UPnP, BlueTooth, 801.11(a, b, c, n, etc.), Ethernet, USB, MPEG 2, 4, WMV AVI, Flash, H.264, and on and on. We got the stuff, with and without wires. We got the file formats, the display formats, and boy do we have the media, it’s coming out of our pores.
But there are petty jealousies combined with downright stupidity. And so you can’t serve iTunes to your PC via Bluetooth, or Frustrated Housewives to your PSP from the TiVo, or show the pictures on your camera phone to anyone via your TV, yet.
But we’re really, really close. In fact I’ll venture a guess that in two years or less this will not only be possible, but commonplace, and our kids will look at us like we’re from Mars when we tell them, “When I was your age…”
So we may not be able to stop global warming, election campaigns, or roadside bombs, but we will see peace in our homes in our life time – I guranetee ya.

Virtual Reality Resolution
M.C Escher Hand with Reflecting Sphere
A number of months ago I visited a defense contractor who is making virtual reality training simulations for the military. To use the system people put on a VR headset which has a resolution of 800 x 600. At this meeting I asked the developers what the “virtual resolution” of their world was and the concept was lost to them. Well what I meant was how many pixels are in the universe from a single perspective around the user.
Lately I have been flying Microsoft Flight Simulator X with a TrackIR head tracking device which allows me to look around. A static viewpoint is 2560 x 1600 and I can find about six views from the cockpit that do not overlap. So using my concept of Virtual Reality Resolution - the pixel count is (2560x1600) * 6 = 24,576,000
I guess the field of view plays a part in this as well. What I’m driving at is a way to measue the VR world visual definition fidelity by a theoretical sphere of pixels around a user. The larger the pixels; the smaller possible number of pixels - and the less possible visual reality and immersion. On the flipside - the smaller the pixels, the more that can be fit into the sphere - to a theorertically ifinite level. If the Star Trek Holodeck existed - how many pixels would be neeeded to create the illusion of reality? I’m just thinking out loud and may be missing something or someone who has already delved into this area.

The New Communications Tools…Listening, Helping
Guest blogger Andy Marken has weighed in with his very opinionated view on how, exactly marketing professionals are going to have to change their ways in order to take advantage of the new order: Web 2.0. It’s not business as usual and it’s going to require new attitudes as more people get in on the act.
By G.A. “Andy” Marken, Marken Communications Inc,
Marketing and communications “experts” like to tell us how the Internet and Web 2.0 have opened up new opportunities for the industry to reach out to and influence people in new, exciting, more effective ways.
Instant information web sites, 10s of thousands of them are ready for your news bloggers, almost free social networks in which you can embed your news. Unique opportunities for the company to tap directly into the consumer before he/she makes a purchase.
How much better can it get?
Marketing is fired up, and in unison they ask:
- Did you send them the well crafted release we approved?
- How many clips/hits did you get?
- Why are you working with XYZ user community group? How many buyers are there?
- Why did you send product to him/her to review…it’s just an ego, self-expression blog?
Managers and communications people talk the talk when it comes to blogs, podcasts, UGs, social sites. But, at the same time they:
- Emphasize spending their time on “tier one,” media
- Measure performance and results on the volume of media clips/hits
- Question the reach/influence of specialized user groups/communities
- Ask how many people be influenced by an existing customer influence/sell
- Question the ROI is of a blogger who might have 500 readers a month
- Wonder how to handle it when a blogger writes something negative about the company/product
Social networking really isn’t anything new. It has just taken its individual and collective voice online.
The Audience(s)
Social networking locations are roughly described as:
- rating, review sites – expressing an individual’s self-esteem and providing information/assistance/guidance
- video, content sharing sites – is all about expressing your identity (10s of thousands of new segments posted for viewing/sharing every month)
- blogs – a way people express their identity, focus on showing their status or improving their self-esteem, providing unique information, insights, assistance (thousands are brought online each month). The community is loosely defined with paid bloggers, ego bloggers, helpful or venomous bloggers. Most every editor, reporter, analyst has his/her own blog where he/she puts down information, ideas, and thoughts that don’t fit in their publication; editorial guidelines; or something simply needs to be said.
- specialty groups – individuals/organizations that come together because they share a common interest and want to share/learn from like individuals (name any subject, there’s an online community)
- social networks – these can be profile-driven (audiophiles, videophiles, Jaguar enthusiasts, etc) – affiliation/belonging – or purpose-driven (video post production groups, home theater specialists, auto restorers). Again it is subject, sharing a common interest/value, being part of a community.
What we have to get past is the focus of tier one, tier two locations/individuals.
Everyone who wants information/assistance is important.

Each can influence the image of the company and its products.
They’re all part of the new media frontier.
Fading Importance
In the brave new communications world, less importance is being placed on the basic public relations tool – the news/press release – and greater attention on relationships. Increasingly members of the media view the well-crafted, thoroughly reviewed announcement sent out over the wire or distribution service as old news by the time it arrives. Everyone receives the information, so it’s of comparatively less importance.
News people – print, radio/TV, web, blog – now have new sources. They are very adept at searching the web—scanning white papers, event listings, price changes, job openings, special interest portal sites, user forums and online newsletters.
They find two or three disconnected ideas and piece together their own story lines. As a result, despite what many believe the release is the beginning of the process, not an end product in today’s always on online world.
New Platforms
Finding, tracking and handling social media coverage of company/product news, information/misinformation and issues is a significant challenge for PR/communications people. Social media isn’t traditional media. Rather, social media is more a form of personal discussions. Old-fashioned media service email/telemarketer pitches may get you in print…negative print but print just the same.
Bloggers come in all shapes, sizes, ages and backgrounds. Some are non-journalists; some are seasoned professionals; some are people passionate about a company, product, technology, subject; some are simply passionate about seeing their ideas/opinions read. Then, there are some who have made their mind up before they talk with you; some have an axe to grid, and others (most) are open to discussions, ideas.
The only best approach for the marketer in this brave new world is to listen, gain insights, develop ideas before you launch your blog/podcast program. Next to getting product and service recommendations from user review sites or from friends or other authorities, blogs are almost as credible as word of mouth recommendations.

Value Proposition
One of the greatest opportunities for companies, the most challenging and the most difficult to quantify are user reviews – user groups, blogs, social nets.
It is impossible for public relations to point to a circulation of 10,000, 100,000, 1,000,000 and show any true ROI (return on investment) for someone writing a review or talking about a company/product/service.
Study after study shows that consumers today go online to research a subject, product, solution before they buy.
The first thing the prospective customer searches out is user reviews followed by comparison charts and expert reviews.

Conventional news media may make the consumer aware of the product/service but people make their buying decisions from peer recommendations. Not from the manufacturer’s web site or literature, not from the retail clerk, not from the expert’s recommendations.
Social Nets – Common Interest
Social networks like MySpace, YouTube, Plaxo, Facebook, LinkedIn and thousands of niche interest, professional and avocation site members come together because of a common interest. They are also superior avenues for reaching influential decision makers and consumers.

People around the globe are members of these sites because they are able to exchange information, ideas and problems/solutions on specific business, personal or professional topics.
Locations like DigitalMediaNet, OcModShop, Tom’s Guide, AnandTech, CDFreaks, audiophile, digitalmediathoughts and hundreds of horizontal and vertical interest sites have forums, blogs and news available in one community location.
They represent fantastic opportunities for people to get a quick understanding and indoctrination into the tight social network community where common goals, common problems are shared/resolved. They are such rich locations that many public relations/communications and marketing individuals look at the locations as narrowcast goldmine opportunities.
Wrong !
Sit on the sidelines. Listen. Observe.
There will be times and opportunities for company representatives – openly identified – to add information and ideas.
But regardless of how the online discussion flows, these social sites are one of the best product/service focus groups in the world. They have free and open discussions. Even negative statements can yield positive returns for the company in the shape of new policies, new products, new ways of thinking and new methods of working with consumers.
In the new Web 2.0 environment communications people have to understand, appreciate and embrace the idea that:
- there is no local market or territory any more. We work and live in a global market and information community
- we must have open and continual conversation with our consumers and partners as a group and individually
- the company may have 10 million customers but each is an individual with unique wants and needs
- once you step into the Web 2.0 world you have to take the good with the bad and win one customer, one user at a time
Public relations thinking that encompasses message management, branding and compunctions distribution pipelines is broken. It will never be as it was before.
Professionals have to understand the power and influence word of mouth, blogs, social networking communications has in the digital world.

There is no clear cut ROI but the dangers of ignoring these communities are obvious.
Public relations or communications people who ignore customer issues because “it isn’t my job,” are missing a golden opportunity to get personal inputs on the person’s image of the company, why the individual bought the product/service, what they like/dislike and what they feel should be improved. It doesn’t take many of these discussions to see a market pattern.
Certainly it can be a dangerous when you begin your digital world trip. Safety in the trip depends on your ability to shut up…listen…help.
It is the only way your company and you can be certain both make the trip successfully.

Educating the next crop of engineers
As I pondered this ponderous title and the challenge it represents for me to lead the round table at COFES it got me thinking about how we learn.
Studies have shown that children learn fast and do so until they become 19 to 20 years old, then their brains become less flexible and learning takes longer, and it’s more difficult. By the time one reaches full adulthood and middle age you really have to work at it to learn new things; languages are particularly difficult because of the contextual and grammatical differences, they don’t easily fit our well honed models and views of the world.
Engineering is a language, as is medicine, music, and art. And not everyone is able to learn those subjects as easily as others, someone good in art may do poorly in medicine, although there does seem to be a natural linkage between engineering and music.
As we grow we learn not just facts but also falsehoods, philosophies, and fears. And those fears, philosophies, and falsehoods prevent us from learning other, usually important, and often enriching things – we are cast into a channel of self imposed ignorance.
It’s these falsehoods that are the greatest barrier to children entering the field of engineering. These localized common wisdoms found in school yards, barber shops, and local hangouts inhibit and stifle a child’s potential. They are taught that they can’t do certain things, or that such things are too hard, or not cool. The teachers are presenting their own failures as fact, and sadly embedding the crippling idea, don’t try you’ll only fail, into supple young minds.
Some however are so drawn to a vocation or profession that no amount of obstacle, peer pressure, or parental abandonment can dissuade them. They are the lucky ones, the ones who have found a passion early in life and managed to pursue it, and probably do well at it. And whereas we can’t ignore these people, they don’t need as much of our attention as the left behinds and passed over. The challenge is plucking the marginalized children out before they get too stuck in self inhibiting ways and can’t be inspired.
And so with regard to engineering, I think there could be simple tests, tests that are not formed like a test (and certainly not an element of the disastrous No Child Left Behind fiasco.) Rather testing would be coupled with sensitivity training for teachers, counselors, coaches, and other adults involved in the management, guidance, and education of children. The goal would be to identify those students who have a natural knack for problem solving, mechanics, and systems. And even though the theme of this rambling diatribe is about how to find and encourage the next crop of engineers, it is not constrained to just that narrow field of endeavor. The abilities we’re looking for apply equally to an orthopedic surgeon, and maybe even a composer.
In the past, in most countries including the United States and especially those countries with centrally controlled economies, aptitude testing was the norm. Children were evaluated at various grades, often as a way of directing them into studies where they would be best suited to make the greatest achievement (and subsequent contribution to society.) That concept has been abandoned in the US as being narrow minded and limiting. The idea being that testing and directing children towards particular areas of study limits a child’s self expression. Admittedly, using testing to sort children into rigid career paths or trade schools can be dangerous, cruelly limiting a child’s future. But to completely abandon the idea of testing in order to nurture and foster children’s aptitudes is also a mistake. I think it’s especially a mistake in underprivileged schools where children may not have a strong home life and learn about the world on the streets from people no better educated than they are. These are precisely the kids that need focused attention early in their careers.
One of the excuses for not providing such evaluations and guidance for children is the limitations in staff and of teachers. The teachers are over burdened with large classes, and administrative tasks such as checking home work, grading papers, submitting lesson plans, that eat into their time to offer any personal guidance.
So I have a proposal.
We hear the lament of industry that the US does not have sufficient technical people and therefore we should open up our immigration policy to allow more foreign workers in (H-1B visas.) However, if the industry would apply some of its resources to augmenting the schools with special information and teaching programs, evaluations of students, and guidance for students that show promise, I think US industry could find all the technical people it needs. The problem for US industry is that such a program would take at least 15 years from first contact in grammar school and US industry wants an instant solution. Therefore, I propose the government grant the opening up of H-1B visas but with the provision that US industry pay a special tax to a fund for the evaluation, training, and most importantly, guidance of US students (regardless of where they were born.)
I further suggest that our professional societies assess their members an additional fee (some do this now as an educational fund) for student evaluation programs that are combined with student guidance programs.
I believe there are hundreds of thousands of potential engineers in grammar, middle and high school right now. In our ever more complex and challenging world—and especially so in the US—we need more engineers and technicians than ever before. We have these bright young flowers, let’s find creative and imaginative ways of encouraging them before they get lost in the weeds.
