Edge Computing

1
Edge Computing

• Computing at the Edge of the Internet

2
Introduction

• Michael Baker
• Edge computing

3
Topics of Discussion

• What is edge computing?
• SETI_at_home
• Future of edge computing

4
What is Edge Computing?

• Internet-connected PCs
• No fixed IP address
• Edge cycles
• Edge resources

5
Edge Computing Power

• Conservative estimate
• 100 million PCs
• 100 MHz CPU
• 100 MB hard drive
• 10 billion MHz CPU
• 10,000 TB of storage

6
Edge Computing Characteristics

• Decentralized
• Outside the DNS system
• Unpredictable IP addresses
• Unstable connectivity

7
Practical Benefits of Decentralization

• Cooperative ownership
• Features (services)
• Cost
• Administration

8
Other Edge Computing Issues

• Bypassing DNS system
• Machine-centric world view of DNS
• Autonomy of nodes
• Ownership

9
Strategies for Bypassing DNS

• Create directory of protocol-specific addresses
• Use numeric IP addresses
• Scheduling, fixed addresses

10
Edge Resources

• Storage
• Cycles
• Content
• Human presence

11
Notion of Presence

• Managing presence
• Human vs. machine presence
• Authentication

12
Virtual Mainframe

• P2P
• Napster
• Implicit agreement

13
P2P Litmus Test

• Assumes temporary IP addresses
• Variable connectivity
• Autonomy of nodes

14
Instant Messaging

• 2-peer example
• No central server
• Problems

15
No Central Server

• Scalable
• Robust
• Fast

16
Problems

• Firewalls
• Security
• Presence information

17
SETI_at_home

• Most compelling example of edge computing
• SETI_at_home statistics
• Future of SETI_at_home

18
Quintessential Edge Computer

• Computing power
• Growth in popularity
• Security

19
SETI_at_home vs. Supercomputer

• IBM's ASCII White
• 12 TFLOPS
• 110 million
• SETI_at_home
• 25 TFLOPS and growing!!!
• 500K so far

20
SETI_at_home Popularity

• Shows results
• Eye-catching screensaver graphics
• Certificates of participation
• Credit for discovering extraterrestrial life

21
