Computing: Where Have We Come From?

• Computers, Communications and Broadcasting are CONVERGING

• Computers started over 60 years ago – Initially seen as ‘mathematical’

• But - Alternative view: computer as a communications device (c.f. Colossus code-breaker)

Page 4: Visions of the Future of Computing Professor Peter Excell Professor of Communications / Athro Cyfathrebu Glyndwr University / Prifysgol Glyndŵr.

Where Have We Come From?

• 60s/70s: networking and Arpanet Internet

• 60s: Telephone networks adopted digital (PCM) systems

• Telephone Exchanges hence become a form of computer

Page 5: Visions of the Future of Computing Professor Peter Excell Professor of Communications / Athro Cyfathrebu Glyndwr University / Prifysgol Glyndŵr.

Parallel and Vector Computers

A ‘Big Iron’ view of the way forward

• SISD: single instruction, single data

• SIMD: single instruction, multiple data

• (MISD: multiple instruction, single data)

• MIMD: multiple instruction, multiple data

Page 6: Visions of the Future of Computing Professor Peter Excell Professor of Communications / Athro Cyfathrebu Glyndwr University / Prifysgol Glyndŵr.

Parallel and Vector Computers

Flops: floating-point operations per second

• MegaFlops – 106

• GigaFlops – 109

• TeraFlops – 1012

• PetaFlops – 1015

• Exaflops - 1018

Page 8: Visions of the Future of Computing Professor Peter Excell Professor of Communications / Athro Cyfathrebu Glyndwr University / Prifysgol Glyndŵr.

Parallel and Vector Computers Cray’s philosophy: build maximum-speed serial processors first

(vector processors), then parallel them if necessary.• Cray’s career: CDC 6600, 7600, Cray 1 - vector processors

for SIMD (not parallel as such)• Then cautious parallelism: Cray 2, X-MP, Y-MP • Then more parallelism, using torus structure: Cray T3D, T3E • Cray was much more successful than his rivals, but he relied

on Cold-War defence funding.• Japanese fifth-generation project: machines following Cray’s

philosophy from Fujitsu, Hitachi and NEC • Problems in parallelisation (or vectorisation) of problems and

software: some think it should be transparent, but that often seems to fail.

Page 9: Visions of the Future of Computing Professor Peter Excell Professor of Communications / Athro Cyfathrebu Glyndwr University / Prifysgol Glyndŵr.

Parallel and Vector Computers Parallel wreckage in the dustbin of history: • Floating Point Systems Corp.• Kendall Square Research Corp.• The Connection Machine (Thinking Machines Corp.)• Convex Computer Corp.• Inmos Transputer• Meiko Computing Surface• CDC Cyber 205 computer (Cray-1 rival)• eta-10 (CDC’s last fling)• Parsytech GmbH• Cray-3 and 4 computers (planned but never built)• occam parallel programming language• Dataflow computer architecture

Page 10: Visions of the Future of Computing Professor Peter Excell Professor of Communications / Athro Cyfathrebu Glyndwr University / Prifysgol Glyndŵr.

Parallel and Vector Computers Structures:

• Parallel Virtual Machine (PVM)

• Message passing interface (MPI)

• Beowulf systems

• Grid

• Multicore

• Cloud

Page 11: Visions of the Future of Computing Professor Peter Excell Professor of Communications / Athro Cyfathrebu Glyndwr University / Prifysgol Glyndŵr.

Parallel and Vector Computers What about Quantum Computing?• Seems to be a sort of super-parallel machine• No clear view of when will become viable• Could be driven by intelligence needs

Where Have We Come From?• Computer communications:

at first for ‘serious’ uses• Early PC uses also ‘serious’• PC business almost died,

then Cold War ended• Mass market had to be

appealed to• Consumer applications threw

up worthwhile new challenges

• Moore’s Law: a major influence on strategy

Page 15: Visions of the Future of Computing Professor Peter Excell Professor of Communications / Athro Cyfathrebu Glyndwr University / Prifysgol Glyndŵr.

• The ‘Home Computer’ was evolving incrementally (e.g. Apple II), then IBM stormed in, rushing to get into the PC business.

• 3 dreadful business errors meant IBM threw away its hardware and software:– Compaq hacked BIOS (legally), because it wasn’t

protected properly: this led to the burgeoning of PC clones– The best OS company (CP/M) was scared off by non-

disclosure agreements: the OS business was then given to Microsoft on a much weaker basis

– Microsoft was assigned rights to all software

The Rise of the PC: An Extraordinary

Shambles

Page 16: Visions of the Future of Computing Professor Peter Excell Professor of Communications / Athro Cyfathrebu Glyndwr University / Prifysgol Glyndŵr.

Further:• The GUI and mouse concepts were developed at

Xerox PARC – not seen as of value to Xerox• Essentially copied by Apple• Then copied by Microsoft

Other business failures:• BBC Microcomputer, Acorn, Sinclair, Amstrad,

Commodore, Tandy..

The Rise of the PC: An Extraordinary

Shambles

Page 17: Visions of the Future of Computing Professor Peter Excell Professor of Communications / Athro Cyfathrebu Glyndwr University / Prifysgol Glyndŵr.

Where Have We Come From?Communications:• Optical fibres huge capacity packetised

messages Internet• Crucially dependent on a computer at each end of

link• GSM revolution (digital mobile phones)• Highly complex - but cheap processors - mass

market justifies huge investment, leading to commoditisation

• Upgrade path mapped: 2.5G – 3G – 3.5G – 4G• 5G – millimetre-wave??

Page 18: Visions of the Future of Computing Professor Peter Excell Professor of Communications / Athro Cyfathrebu Glyndwr University / Prifysgol Glyndŵr.

Where Have We Come From?

• Mobile is established part of everyday life worldwide

• No. of subscribers over 4 billion – i.e. about 3 people in 5 in the World– Will be 1 in 1 soon (already reached in Europe)

• (c.f. PCs – market saturated at a much lower level? Is this market dominated by relatively affluent males??)

Page 19: Visions of the Future of Computing Professor Peter Excell Professor of Communications / Athro Cyfathrebu Glyndwr University / Prifysgol Glyndŵr.

Where Are We Going? • Mobile phone: has more processing power than

recent-past PCs• Mobile has increasing Internet ability• All it needs to replace the PC is storage and better

HCI (human-computer interface):– Miniature hard disks already available (e.g. in iPod)– Input: e.g. voice recognition, handwriting recognition,

folding/miniaturised keyboards – 3.5G laptops – Output: larger video displays in phones, unfurlable

screens, ‘head-up’ display devices

Page 20: Visions of the Future of Computing Professor Peter Excell Professor of Communications / Athro Cyfathrebu Glyndwr University / Prifysgol Glyndŵr.

Where Are We Going? iPhone: amazing triumph of

coolness plus usabilityBlackberry’s response:

Page 30: Visions of the Future of Computing Professor Peter Excell Professor of Communications / Athro Cyfathrebu Glyndwr University / Prifysgol Glyndŵr.

Where Are We Going? • Raft of ambitious roll-out plans

– 3.5G, 3G-LTE, 4G, 5G - evolved from GSM• SMS MMS; WAP WAP 2 Mobile Internet; email; 3G

with video bandwidth (why not used much?); 4G will have more bandwidth than needed for video….

• WLAN (e.g. WiFi or IEEE 802.11a/b/g/n) a rival technology – was thought might merge with 3G to form basis of 4G – now a sideshow

• Mobile WMAN (e.g. WiMAX or 802.16e/802.20) – another rival for 4G – beaten by LTE

• PANs: Bluetooth (802.15.1); UWB (802.15.3); ZigBee (802.15.4)

• Mobile TV (DVB-H; DMB)

Page 31: Visions of the Future of Computing Professor Peter Excell Professor of Communications / Athro Cyfathrebu Glyndwr University / Prifysgol Glyndŵr.

Where Are We Going?

Can we get a clearer view?

Can we avoid the mistakes of the past?

Page 32: Visions of the Future of Computing Professor Peter Excell Professor of Communications / Athro Cyfathrebu Glyndwr University / Prifysgol Glyndŵr.

Technological Forecasting

A necessarily imprecise management tool that attempts to predict the evolution of technology in the near-term future.

Page 33: Visions of the Future of Computing Professor Peter Excell Professor of Communications / Athro Cyfathrebu Glyndwr University / Prifysgol Glyndŵr.

Why is it important?

▪    All technology-based companies, and most individuals, have to form a view about the near-term evolution of technology, to decide on investments, purchases, life plans and career paths. ▪    We are living through a particularly exciting time in the evolution of technology: ▪    Computers; Mobile phones; (insert your favourite here)

Page 35: Visions of the Future of Computing Professor Peter Excell Professor of Communications / Athro Cyfathrebu Glyndwr University / Prifysgol Glyndŵr.

The Kurzweil Singularity

Peter Cochrane (ex BT futurologist):“In my estimation it will go something like this:2006 internet ~ 1 human brain 2012 internet ~ 1,000 human brains2018 internet ~ 1,000,000 human brains2024 internet ~ 1,000,000,000 human brains2034 internet ~ 1,000,000,000,000 human brains”

Already, we can read people’s minds, crudely, using MEG (Magnetoencephalography): by 2100 it is reasonable to expect that this will have enough resolution to enable the complete brain contents to be downloaded

Page 36: Visions of the Future of Computing Professor Peter Excell Professor of Communications / Athro Cyfathrebu Glyndwr University / Prifysgol Glyndŵr.

Futurology: an Aid to Insight Millimetre Timeline focuses thoughts:1mm 1 year1 metre 1000 years1km 1 million years1000 km 1 billion years

So:The Renaissance ~40 cmIndustrial Revolution ~20 cmComputing ~6.5 cm- The blink of an eye…

Page 37: Visions of the Future of Computing Professor Peter Excell Professor of Communications / Athro Cyfathrebu Glyndwr University / Prifysgol Glyndŵr.

Digital Examples ▪    The PC, contrary to the expectations of only a few years ago, has become a widely used device and the dominant form of computer. And yet it shows signs of having reached a plateau.▪    Meanwhile, the mobile phone has become even more widespread around the world and appears likely to acquire all of functionality of the PC within a short time.

Page 38: Visions of the Future of Computing Professor Peter Excell Professor of Communications / Athro Cyfathrebu Glyndwr University / Prifysgol Glyndŵr.

Personal Perspectives Several technologies have effectively died out over recent decades: can we predict when this will happen, to avoid damage to our careers?

Radio Valve

Page 39: Visions of the Future of Computing Professor Peter Excell Professor of Communications / Athro Cyfathrebu Glyndwr University / Prifysgol Glyndŵr.

Personal Perspectives Recent ‘deaths’:

• CRT screens• Incandescent light bulbs• Analogue TV• Film cameras• Floppy disks • Vinyl records• Tape?• 1G mobile

Page 40: Visions of the Future of Computing Professor Peter Excell Professor of Communications / Athro Cyfathrebu Glyndwr University / Prifysgol Glyndŵr.

Personal Perspectives Several promising innovations have also failed to take off in the way that was hoped: can we predict this better?

Gas turbine vehicles – Hovercraft – Concorde – Electric vehicles – Betamax – Superconductivity – Transputers – Sinclair QL – Sinclair C5 – Minidisks…

▪   What should we invest our time and money in?

▪   There is thus a need to have a vision of where present and future technologies are heading.

Page 41: Visions of the Future of Computing Professor Peter Excell Professor of Communications / Athro Cyfathrebu Glyndwr University / Prifysgol Glyndŵr.

Personal Perspectives

C.f. The remarkable failures of forward vision in the mobile industry:

▪ The unexpected success of SMS▪ The marketing debacle of WAP-1 ▪ The extraordinarily low uptake of video telephony▪ The unexpected success of the iPhone

Page 42: Visions of the Future of Computing Professor Peter Excell Professor of Communications / Athro Cyfathrebu Glyndwr University / Prifysgol Glyndŵr.

Great Blunders in Forecasting I think there is a world market for maybe five computers. Thomas Watson, chairman of IBM, 1943

Computers in the future may weigh no more than 1.5 tons. ‘Popular Mechanics’, forecasting the relentless march of science, 1949

It would appear that we have reached the limits of what it is possible to achieve with computer technology, although one should be careful with such statements, as they tend to sound pretty silly in 5 years. John von Neumann, computing pioneer, 1949

Page 43: Visions of the Future of Computing Professor Peter Excell Professor of Communications / Athro Cyfathrebu Glyndwr University / Prifysgol Glyndŵr.

Great Blunders in Forecasting

British government calculation, early 1950s, to establish the size of the market for computers:

Computers do arithmetic, so estimate the total number of arithmetic calculations being done by human beings (principally financial clerks) and calculate how many contemporary computers were required to replace this work…

Answer: 4 (but add a 5th one in Scotland for political reasons)

Page 44: Visions of the Future of Computing Professor Peter Excell Professor of Communications / Athro Cyfathrebu Glyndwr University / Prifysgol Glyndŵr.

Great Blunders in Forecasting There is no reason anyone would want a computer in their home. Ken Olson, president and founder of Digital Equipment Corp., 1977

640K ought to be enough for anybody. Bill Gates, 1981

Page 45: Visions of the Future of Computing Professor Peter Excell Professor of Communications / Athro Cyfathrebu Glyndwr University / Prifysgol Glyndŵr.

Great Blunders in Forecasting By the mid-1980s the home computer boom appeared to be nothing more than a short lived and, for some computer manufacturers, expensive fad. … As a result a device that was initially heralded as the forerunner of a new technological era was a spectacular failure that threatened to bankrupt the firms that had invested billions of dollars in its development.

From "The Evolution of Technology" by George Basalla (Department of History, University of Delaware), Cambridge University Press, 1988 (reprinted 1995)

Triggers for the Decay Phase

Michael Duffy’s concept of ‘Design Impasse’: improvements are physically possible, but effort is better directed elsewhere(Duffy, M.C. Technomorphology and the Stephenson traction system. Trans. Newcomen Society, Vol. 54 (1982-83) pp. 55-78)

E.g. The ‘Sailing Ship Effect’; Steam engines

Page 49: Visions of the Future of Computing Professor Peter Excell Professor of Communications / Athro Cyfathrebu Glyndwr University / Prifysgol Glyndŵr.

Moore’s Law Gordon Moore, of Intel, made a prediction about the rate of increase of processing power (or “intelligence”) of microprocessors.

He said that the number of transistor gates on a silicon chip would double every 18 months. He made his prediction around 1965 and, amazingly, it has held true ever since. This is known as Moore’s Law.

Not a law of physics: it is partly a self-fulfilling prophecy, because Intel’s shareholders would think the company had a problem if it could not maintain this rate of progress, but would suspect it was spending too much on R&D if it exceeded it.

Moore’s Law

This has led to Commoditisation of computing, e.g.:

Ubiquitous/ Speckled computing

RFID tags Soon to be everywhere, not just a replacement for barcodes, they have intelligence and rewritable memory

IPv6 addresses Will enable huge numbers of artefacts to have an Internet address

Page 55: Visions of the Future of Computing Professor Peter Excell Professor of Communications / Athro Cyfathrebu Glyndwr University / Prifysgol Glyndŵr.

Delphi Method for Futurology▪   Delphi Method: iterate expert opinions

The simple artifice of keeping the experts apart and keeping their responses anonymous frees them to think radically, creatively and independently, and this gives the most useful result from the exercise.

Page 56: Visions of the Future of Computing Professor Peter Excell Professor of Communications / Athro Cyfathrebu Glyndwr University / Prifysgol Glyndŵr.

Are Computers Different?

• Computer and software technologies appear to be qualitatively different.

• Because they possess a degree of 'intelligence', they have more ability to 'reinvent themselves' and hence break the life-cycle pattern of the past.

• E.g. the PC is almost an entirely different product from 1st-generation computers

• A PC running Word is effectively a different device from one running a game

Page 57: Visions of the Future of Computing Professor Peter Excell Professor of Communications / Athro Cyfathrebu Glyndwr University / Prifysgol Glyndŵr.

Are Computers Different?

This raises questions about the definition of a ‘Technology’ in the Technology life cycle

- Will computers as such become obsolete?- Doesn’t look likely?

Moore’s Law and mobile bandwidth

Page 59: Visions of the Future of Computing Professor Peter Excell Professor of Communications / Athro Cyfathrebu Glyndwr University / Prifysgol Glyndŵr.

Bandwidth

A measure of the rate at which information is transferred

Analogue version: frequency bands– Voice needs about 5kHz– TV needs about 5MHz– So, “a picture is worth a thousand words”

Page 60: Visions of the Future of Computing Professor Peter Excell Professor of Communications / Athro Cyfathrebu Glyndwr University / Prifysgol Glyndŵr.

Bandwidth • 802.11a/b/g WiFi: 11/22/50Mbps

• 802.11n – aiming for 500Mbps guaranteed

• 802.16 WiMAX: 70Mbps

Pace of change is faster than Moore’s Law

All brilliant technology, but what will it be used for?

Page 61: Visions of the Future of Computing Professor Peter Excell Professor of Communications / Athro Cyfathrebu Glyndwr University / Prifysgol Glyndŵr.

Human Communication Bandwidths

• Human Input– Very high quality video (~100Mbps??)– Good quality audio (~100kbps??)– Other sensations – hard to quantify

• Human Output– Low quality audio (~20kbps?)– Typing (~1kbps?)– Gestures and body language – hard to

quantify– Does deaf sign language give us some clues?

Page 62: Visions of the Future of Computing Professor Peter Excell Professor of Communications / Athro Cyfathrebu Glyndwr University / Prifysgol Glyndŵr.

Human Communication BandwidthsSo the human being’s communications abilities are

very asymmetrical (by ~5000 times)

Compare this with ADSL (popular broadband technology): ‘A’ stands for ‘asymmetric’: the system uses 4 times the capacity for ‘downlink’ traffic (i.e. to the consumer) as ‘uplink’ (from the consumer)

Is this a good thing? Should we facilitate people being more creative??

Page 63: Visions of the Future of Computing Professor Peter Excell Professor of Communications / Athro Cyfathrebu Glyndwr University / Prifysgol Glyndŵr.

Future Concepts • Clear logic of convergence is that a high-end

future mobile will have – processing and storage capabilities similar to a good

contemporary PC and – communications ability in Megabits/sec (WLAN/

WMAN/ 4G)

• Adding convenient and not-too-conspicuous human-computer interface means device will have to be distributed around the body– in other words it will become the same as the ‘wearable

computer’ but with a wide-band radio modem

Page 64: Visions of the Future of Computing Professor Peter Excell Professor of Communications / Athro Cyfathrebu Glyndwr University / Prifysgol Glyndŵr.

Future Concepts • More radical ideas need to be considered for the

way in which it would be used • Cabling objectionable – use wireless (e.g.

Bluetooth) – leads to BAN/PAN concept (Body/Personal Area Network)

• But: charging or other power supply a problem– Energy harvesting needed

• Wearable components: – CPU, possibly separate storage unit,– combined retinal projection unit, earpiece and

microphone, – wrist-mounted keypad/mouse unit, – radio transceiver (on belt or in shoe to provide power)

Page 75: Visions of the Future of Computing Professor Peter Excell Professor of Communications / Athro Cyfathrebu Glyndwr University / Prifysgol Glyndŵr.

Future Concepts Think laterally!Generator (later transceiver) in the shoe

Page 76: Visions of the Future of Computing Professor Peter Excell Professor of Communications / Athro Cyfathrebu Glyndwr University / Prifysgol Glyndŵr.

How would such a system be used? • Video phone communications on the move?

Certainly, but not all of the time. • E-mail, with optional added pictures or non-real-

time video? Yes, this is likely to be a major source of traffic.

• Web browsing? Yes, but not much of the time. • Employer information? Very possibly, but not much

outside working hours. • Immersive gaming? Possibly, but not for the

majority and not in working hours. Is this all? • Mobile TV? Rubbished until recently; now might

make it?

Page 77: Visions of the Future of Computing Professor Peter Excell Professor of Communications / Athro Cyfathrebu Glyndwr University / Prifysgol Glyndŵr.

How would such a system be used? Need to break from the Microsoft

HAPPI: One Vision of the Future

Personal advisor: a vision from 1980 (IEEE Spectrum)

A cartoon, but the idea has merit

Page 79: Visions of the Future of Computing Professor Peter Excell Professor of Communications / Athro Cyfathrebu Glyndwr University / Prifysgol Glyndŵr.

HAPPI: One Vision of the Future• HAPPI: ‘Human-as-peripheral paradigm

initiative’• Hence human user will become an appendage

attached to global intelligent network • Standard caricatures depict a frightening and

dehumanising experience: justified?• Consider user with mental handicap –

computer/network acts as helper/advisor

Page 80: Visions of the Future of Computing Professor Peter Excell Professor of Communications / Athro Cyfathrebu Glyndwr University / Prifysgol Glyndŵr.

HAPPI: One Vision of the Future• Should such aids be limited to the handicapped?

– If network has potential to be more intelligent and knowledgeable than even the wisest human being, surely it has potential to improve life of any person integrated with it?

• Deep questions arise about nature of intelligence and value and purpose of human life

Page 81: Visions of the Future of Computing Professor Peter Excell Professor of Communications / Athro Cyfathrebu Glyndwr University / Prifysgol Glyndŵr.

HAPPI: One Vision of the Future• This is a good thing: computers and automation

have already freed human beings from doing many monotonous jobs, – so the wearable computer/communications system has

potential to free the human from the great majority of tedious and non-creative activity

– human would be freed to concentrate on faculties that cannot be replicated in a computer

– the human would become akin to a special-purpose ‘peripheral’, with unique abilities, attached to the computer system

Page 82: Visions of the Future of Computing Professor Peter Excell Professor of Communications / Athro Cyfathrebu Glyndwr University / Prifysgol Glyndŵr.

HAPPI: One Vision of the Future• This vision could be realisable within about two

decades:– researchers and industry need to explore such

possibilities (and consider alternative visions)– preparations need to be made, especially in

development of the relevant software/content– potential is challenging, frightening and exciting. It

seems likely to change human life more than any other technology

– Even those who object to it will be unlikely to be able to prevent its evolution

The Emotional Wardrobe: another vision of the future

Project (with Glyndŵr staff) led by garment design researchers at Central St. Martin’s School of Art & Design, London (CSM).

Investigating technology-enabled garment design

CSM’s specialism is communication of emotions, by sensing skin potentials etc and communicating this as warmth, touch (‘hugs’) and displays– This represents a new human output channel

Immediate tasks• Mobile Content Development

• Expected to be a big business (4+ billion customers)

• Needs creative ideas

• We are developing teaching of this

• New scenarios are currently mainly research, but also some student projects

Mobile vs PCMobile devices have bigger economies-of-scale advantages

They digitally enfranchise more people – in both developed and developing worlds

They facilitate spontaneity – major creative aid

Interest in fixed phones is fading: fixed PCs could be next

But much more needs to be done to make the mobile device a facilitator of enriched life.

So what about traditional computing?

Computer power trickles down to smaller and cheaper units

The screen+keyboard model won’t last for long

Experience with cutting-edge computers helps us to envision what will be commonplace tomorrow

HPC Wales project coming….

Future Ubiquitous ComputingIntegrated Product Design Approach:

1. Engineering design (of the internal electronics) to function reliably and at an economic cost

2. Physical product design (aesthetics, ergonomics)3. Software design, to achieve a useful/desirable

purpose reliably and at an economic cost4. Human interaction design: aesthetics,

meaningfulness, engagement…5. The business model (it’s no good making a loss!)

Conclusions• The future will be very exciting for computer-based technology.• Our wilder ideas are more likely to come true than conservative visions.• Moving from the big-government leadership of technology in the Cold War era, to the consumer-led situation today has been far better for progress than we imagined.• Liberating all the people in the World to do more creative things is a wonderful opportunity that computer and communications technology can facilitate.

ConclusionsWhile many claim that the future will be dominated by biomedical technologies, these are, in the main, only tools to repair people with problems, whereas computer and communications technologies facilitate new opportunities, new products, new ways of living, and liberation of human beings’ potentials.
