lags technology

• New eras of computing start when the previous era is so strong it is hard to imagine that things could ever be different

– mainframe -> mini

• The new dominant use was almost completely absent before.

• Technology spread increases

• Technology discontinuities drive new computing paradigms, applications, system architectures• E.g., Xerox Alto
– 3Ms--1 mips, 1 megapixel, 1 mbps
– Fourth M: 1 megabyte of memory
– From time sharing to LAN-connected client-server with display intensive applications
• What will drive the next discontinuity? What are the new metrics of system capability?

• Technology exists (or will soon) to realize grand visions of where computing can go
• What’s missing?

• Architecture
• Framework that realizes the application vision from emerging technology
– systematic application of design methods
