1. CR18: Advanced Compilers Paper Reading
Tomofumi Yuki

2. HW for this Class 2 or 3 paper reviews Short lab-like exercise
do some performance analysis and write report
Breakdown
reviews 20%
report 10%
paper presentation 70%

3. HW: Paper Review Goal: Tasks Get some experience in paper reading
Learn to write reviews
Learn to concisely summarize key points
Tasks
1. Pick a paper from the provided list
2. Write 1-2 page review

4. What should be in a review?
The following 5 questions must be answered
What is the Big Picture problem?
What is the specific problem
Why is the problem important?
How do they address the problem?
How do they evaluate their approach?
What are possible future work?
What is the key cool idea? (punch line)

5. Example: My 1st Paper The Problem Why is the problem important
we need faster code!
tiling is good but tile size selection is tough
prior work used analytical models that are difficult to build
Why is the problem important
tile sizes have more than 5x impact on performance
~20 analytical models proposed in the past

6. Example: My 1st Paper (cont.)
Approach
machine learning to automate model creation
use large number of training data by synthetic kernels
Evaluation
automatically create models for 6 different combination of machines and compilers
the models all perform well

7. Common Pitfalls Also keep in mind when writing papers!
Focus too much on approach/results
placing in context is really important
Get stuck on some technical details
read a paper in 3 passes (at least)
Believe what authors claim
it may not be what they show
For some papers, the answers are sometimes really difficult to identify
Also keep in mind when writing papers!

8. Example: My 1st Paper (cont.)
Punch Line
taking HW prefetching into account greatly improves accuracy
