Super Computing
From Vector Machines to Clusters
Old times
Basic ideas
 A super computer is like a Ferrari → use specific components
 Super computing is like F1 or WRG → adapt to the application
scenario
Vector Computer (Cray)
Database Computer

Super SIMD (Connection
Machines)
Incredible creativity in
architecture and network design

Distributed Computing
Everything as a Service
Cloud Computing
“A large-scale distributed computing paradigm that is
driven by economies of scale, in which a pool of
abstracted, virtualized, dynamically-scalable, managed
computing power, storage, platforms, and services are
delivered on demand to external customers over the
Internet” (Foster at al.)
SalesForces, Amazon, IBM, Google, Microsoft, Backblaze…
Everything as a service
 Infrastructure as a service
 Platform as a service
 Software as a service
Behind the scene: some kind of a (proprietary) grid

Mobile/Ubiquitous/Pervasive Computing
A Focus on the User
Mobile/Ubiquitous/Pervasive Computing
Mobile communications have freed the user from the Internet plug
3G/4G mobile Internet is as faster as Internet-at-work and Internetat-home
Ubiquity, i.e., Internet-everywhere, is a reality (at least in Western
countries)
A dramatic social (and business) change!
A still-open issue: context-awareness
 what is your device, what are the network conditions?
 where are you?
 what are you doing right now and in the near future?
 what are your preferences?
 Who are your friends?

The Internet of Things
When (Smart) Things Meets Internet
The Internet of Things: Definition
The « Internet of Things (IoT) is […] a dynamic global network
infrastructure with self configuring capabilities based on standard and
interoperable communication protocols where physical and virtual
‘things’ have identities, physical attributes, and virtual personalities and
use intelligent interfaces, and are seamlessly integrated into the
information network.
In the IoT, ‘things’ are expected to become active participants in
business, information and social processes where they are enabled to
interact and communicate among themselves and with the environment
by exchanging data and information ‘sensed’ about the environment,
while reacting autonomously to the ‘real/physical world’s events »
(CERP-IoT)

Applications of the Internet of Things
IoT platforms yet exist: xively (ex-cosm, ex-pachube),
sen.se, etc.

Ubiquitous/Pervasive Computing

Ubiquitous and Pervasive Computing…
The Vision of a Calm Technology
« The most profound technologies are those that disappear. They
weave themselves into the fabric of everyday life until they are
indistinguishable from it »
[The objective of pervasive computing is to ] “ … make a computer so
imbedded, so fitting, so natural, that we use it without even thinking
about it.”
“Ubiquitous (pervasive) computing is roughly the opposite of virtual
reality. Where virtual reality puts people inside a computer-generated
world, ubiquitous computing forces the computer to live out here in the
world with people.”
« A new way of thinking about computers in the world, one that takes
into account the natural human environment and allows the computers
themselves to vanish in the background »
Mark Weiser, Xerox PARC, 1991-
Ubiquitous and Pervasive Computing…
The Vision of a Calm Technology
[M. Satyanarayanan, 2001]
Pervasive computing environment = « one saturated with
computing and communication capability, yet so gracefully
integrated with users that it becomes ‘a technology that
disappears’ »
So:
 “Smart” spaces
 “Invisibility” and transparency
 Scalability
35
Some Key Ideas for an Holistic Vision
The « object-subject » is actor (a first-class citizen) of the “system” / of the
Future
 smart objects / smart everything
 active objects
 “the” cloud
« Intelligence » is, at first, the « network » i.e., the ability to exchange
information / communicate
« Intelligence », is also the ability to self-adapt to the user profile and the
context (« context awareness »), “to weave” into the environment
« Ego » is part of the context
« Intelligence », finally, is the ability to organize:
 autonomously (autonomic computing, self healing…)
 spontaneously
Multi-Scale Ubiquitous Ego-Centric Digital Ecosystem
36
A Partial Conclusion
An incredible change!
A digital world (and digital life)
An (almost) unlimited power of processing, storage,
communication
Unlimited opportunities of new applications
But a coined in the 60’s client-server way of thinking!
And strong concerns about privacy
