Breakthroughs in Computing
Transcript of Breakthroughs in Computing
Insatiable market demand for
doubling, little demand for
Free Space Optical (FSO) at 160 gigabits (Pisa)
THZ radio link at 3 Gbps, some day 30 Gbps
Time for “Glass Roots” to enable real competition
Fiber now 1.1 Pbits
per second with
calls at once!
Picocell approach offers unlimited bandwidth
Haas: Wireless through LED bulbs
Reardon claims “DIDO” system offers full bandwidth to every device in the room
Low power “personal area networks” coming
Spectrum allocation becoming obsolete
But others want to auction and own it
Network “management” & neutrality
Battles more political than technical
GPUs generating too much heat
Portability requires low power
Contact lens projector the holy grail
Registration on real world difficult
VR sports, gaming & shopping
Augmented/Alternate reality games
User Interface Breakthroughs
Replacement for the keyboard needed
Speech Recognition,, natural language & translate
Siri, Watson still have far to go
Gesture interfaces from 3-D cameras
Displays & touch
All while small & efficient
The ball-n-chain: System Administration
Is the Apple “walled garden” the only answer?
Improve performance in face of complexity
Provide real time operations
Cloud computing and apps
Software development needs better re-use
MEMS based gyros, accelerometers
Temperature, current/magnetic fields, pressure
Nanotech chemical & DNA sensors
Tiny cameras & new camera technologies
Open hardware like Arduino
Ultra low power embedded chips (1μa asleep)
Query powered (RFID)
No, not for the smart fridge – still looking for the pony
Coded Aperture Camera
Challenges in interoperability and competition
Will the market accept one dominant “AOL” site for everything?
The challenge of “too much signal.”
How does privacy survive?
Ease of use vital
Global trends seen in streams:
Twitter analysis predicts movie gross
Critical mass vs. open
Distributed efforts have uphill battle
The Controlled Platform
One site for everything
The Giant Gateway to the Web
(but also Facebook)
One Big Cloud
A Vast, Usually Interoperable Bazaar
Who will win?
Who should win?
People buying online from competitor while in physical store
Retailers pray for location based services
Delivery robots promise anything in 30 minutes
Look at your software strategy -- will it work in the multicore cloud future?
Look at your payment and banking systems. What has to change with low-friction digital money?
Evaluate your software systems in the context of "immediate" computing and ubiquitous connectivity
Look at your technology strategies. Are you being open and stupid today in order to be smart tomorrow?
Chip-Multiprocessors: “Single-Chip Cloud” Datacenter on a Chip
48 (45 nm)
Chip-Multiprocessors: High Performance Technical Computing
32 cores X 16-wide-vector ≈ 1 TFLOPS peak
2 (32 nm)
8 (32 nm)
Platforms with a
Culture of Innovation
"Miners" hunt for words that meet a magic test
First to find writes on scroll, verifying it for all
People are anonymous but transactions aren't
No repudiation or ability to fix errors
Probably not the final currency
Lots of legal battles
Lots of startup investment
New user interfaces
Cheap sensors & Low Energy Computing
Controversies & Misconceptions
Spectrum and Bandwidth are abundant
Will Moore's Law continue?
Will nations stop anonymous money?
Whose model will rule the net?
Is there a true internet of things?
