are mixed into

Ethernet Home network
Basic ideas:
1. PC records or plays
thru video cable
channels.
2. PC “broadcasts” art
images, webcams,
presentations,
videos, DVDs, etc.
3. Ethernet not cable?
PC will prevail for the next decade
as the dominant platform…
to HPCC community its COTS!
Moore’s Law to reduce price
 Lack of last mile bandwidth to move
pictures, data, and interact favors
home mainframes aka PCs
 Very large disks (1TB by 2005)
to “store everything” personal
 Screens to enhance use
 Home entertainment server…

Thesis: SNAP: Scalable Networks and Platforms
• upsize from desktop to world-scale computer
• based on a few standard components
• similar to NEC’s Computers &
Communications 1983 vision

Because:
• Moore’s law:
exponential progress
• Standardization & Commoditization
• Stratification and competition
When: Sooner than you think!
• massive standardization gives massive use

Section: The economics of
operating systems and databases
(or why NT has the advantage
over proprietary or vanity
chips and UNIX dialects )
Copyright Gordon Bell & Jim Gray
PC+
The UNIX Trap:
creating the myth of “open systems”
“Standard” now means different!
VendorIX platforms have created the “downsizing”
market that provides an apparent, order of magnitude
cost reduction
Hardware platform vendors lock-in users with servers of
proprietary UNIX dialects and unique chips
to maintain margins for chip and UNIX development
Users hostage with client-server, database, and apps
An implicit or unconscious cartel forms that maintains
the industry status quo
Copyright Gordon Bell & Jim Gray
PC+
The UNIX Cartel and Tax:
It’s not competitive and
it introduces higher downstream costs
xx
10,000 programmers @75 companies maintain dialects
R & D costs $1.4 - $2 billion
Implied selling price $10 - 14 billion for $1.4 billion,
or a sales tax of 1 million UNIX units of $10,000
Cost could be reduced to $400 million for ONE UNIX,
sales price for 1 million units would be $2,400 - 4,000
NT sales price is $650; OS2 needs to sell for $1.2b/6m
Furthermore:
The downstream effects on database vendors is
40% R&D efficiency causing
an implied database tax of 2.5x the sales price!
The downstream effects on apps vendors is similar

In a decade we can/will have:

more powerful personal computers
–
–
–
–

adequate networking? PCs now operate at 1 Gbps
–
–



processing 10-100x
4x resolution (2K x 2K) displays to impact paper
Large, wall-sized and watch-sized displays
low cost, storage of one terabyte for personal use
ubiquitous access = today’s fast LANs
Competitive wireless networking
One chip, networked platforms e.g. light bulbs,
cameras everywhere, etc. managed by PCs!
Some well-defined platforms that compete with the
PC for mind (time) and market share
watch, pocket, body implant, home
Inevitable, continued cyberization… the
challenge… interfacing platforms and people.

 1 Gbps ethernet switches scale to
10s of Gbps, scaling upward
 SP2 scales from 1.2

So where are the challenges?


Continued development based on clusters
… Scalar processors need to compete with
vectors. The U.S. has cast its lot with COTS!
WWW is here. Now exploit it in every respect.


Exploit OSS!
Grid
Application Service Providers for scientific
and technical apps

What am I willing to predict?

Processing can be anywhere…

Maui… in the winter. BW is the limiter!
Japan… if supers are so super, otherwise use
PCs
In the disks
Application Service Providers: separation of
our data from ourselves and businesses
The GRID e.g. biologist & chemist
workbenches iff the IP doesn’t get in way
Collaboration ala astrophysics (high
energy physics, math, earth sci. and any
pure science if pure science continues!)
OSS is the big bang for supercomputing??
