3. 100 Google searches = 30Wh
How much energy do you use when you type in a Google search or watch a
YouTube video?
Google said that
100 searches are equal to a 60-watt light bulb burning for 28 minutes.
"Specifically, we currently use about 0.0003 kWh of energy to answer the
average search query," Google said. "This translates into roughly 0.2g of
carbon dioxide."
2011 PC Magazine
60W
28min
x 100 =
We ICT user should care about energy consumption of the service that we use.

6. Eco Programming
Only using eco platform
is not enough
eco platform + good program = efficient

Only using eco car
is not enough
eco car + bad driving = wasting energy
eco car + eco driving = efficient
eco platform + bad program = not efficient

Distributed Platform consists of
- distributed execute engine: load management and execution fault tolerance
- distributed storage: fault tolerance for persistent data
- distributed memory: fault tolerance for runtime data (temporary data)
- easy to maintain
Flavor
- Web: small and frequent application (affinity and cache consideration)
- HPC: big and long life application (runtime robust, <-homomorphic coding)
For cluster (many servers), high efficient and easy-to-use platform is needed.

Web App Framework History
- simple server framework for cluster
- minimum session, minimum server persistence
- reconsideration of cookie and client (instead of session & load balancer model)
- not only request/response model but also publish/subscribe model or …
Reconsideration of Web App Framework for efficiency
e.g.
HTTP + Cookie + CGI/wsgi/rack/… or PHP
(no session or minimum session framework)

10. Eco PHP Platform
•Eco PHP language= subset of PHP
(optimized for Compiler and CPU like http://asmjs.org/ in JS world)
•Eco programming convention and Eco Programmer
•Eco library
•Eco language engine
•HipHop compiler
•HipHop machine (VM, Processor, SoC)
•Eco framework for cluster
•Application framework with distributed computing
technology
•Disaggregated Rack

11. Eco Programming Culture
new programming culture
Eco programming is more electric-power-efficient
programming. Eco language, eco platform, eco
programming convention, and eco programmer makes
the world better.
eco PHP
is cool!
Like Eco Wordpress

12. Goal
Create new programming culture
• Build eco application framework (eco PHP and middleware)
• Foster eco programmer (eco programming conventions)
Key technology
• Building eco platform to maximize runtime efficiency on OCP
physical system
• Measurement of runtime efficiency

13. MEASUREMENT OF RUNTIME
EFFICIENCY
for the most efficient computing infrastructures

14. Measuring efficiency
Hacking Conventional Computing Infrastructure
We started a project at Facebook almost two years ago with a
pretty big goal: to build one of the most efficient computing
infrastructures at the lowest possible cost. We decided to honor
our hacker roots and challenge convention by custom designing
and building our software, servers and data centers from the
ground up – and then share these technologies as they evolve.
Measure the runtime efficiency

• HipHop Project (PHP Compiler, PHP VM)
• Processor or SoC Project? (Intel, AMD, ARM, …)
• Disaggregated Rack
