447 Strikes Back

 Who has taken 447?

 Do you remember the first assignment?

 Have you done it?

Question: What Is This?

Answer: Masterpiece of A Famous Architect

Recall: But First, Today’s First Assignment

 Find The Differences Of This and That

Find Differences Of This and That

Recall: A Key Question

 How Was Wright Able To Design Fallingwater?

 Can have many guesses

 (Ultra) hard work, perseverance, dedication (over decades)  Experience of decades  Creativity  Out-of-the-box thinking  Principled design  A good understanding of past designs  Good judgment and intuition  Strong combination of skills (math, architecture, art, …)  …

 (You will be exposed to and hopefully develop/enhance many of these skills in this course)

A Quote from The Architect Himself

 “architecture […] based upon principle, and not upon precedent”

A Quote from The Architect Himself

 “architecture […] based upon principle, and not upon precedent”

Recall: Role of the (Computer) Architect

from Yale Patt’s lecture notes

Recall: Role of The (Computer) Architect

 Look backward (to the past)

 Understand tradeoffs and designs, upsides/downsides, past workloads. Analyze and evaluate the past.

 Look forward (to the future)

 Be the dreamer and create new designs. Listen to dreamers.  Push the state of the art. Evaluate new design choices.

 Look up (towards problems in the computing stack)

 Understand important problems and their nature.  Develop architectures and ideas to solve important problems.

 Look down (towards device/circuit technology)

 Understand the capabilities of the underlying technology.  Predict and adapt to the future of technology (you are designing for N years ahead). Enable the future technology.

Agenda

 Course Overview

 Assumed Background (Videos and Lectures to Study)

 How to Jump Into Research

 How to Do the Paper Reviews

 Some Promising Research Topics in Computer Architecture

 First Assignments (for Next Week)
