Peephole contest: rules and prizes
Part of the A+ JOOS project involves the design and implementation of
peephole patterns that operate on an intermediate representation of
Java bytecode. Each project group submits a collection of peephole
patterns that attempts to minimize the number of bytes required by
JOOS methods, and these collections then compete against each other.
The rules are as follows:
- Each project group may submit only one entry.
- An entry is a collection of peephole patterns as defined by the
requirements of the A+ project.
- All unsound patterns are deleted from the collection.
- A pattern is judged to be unsound by the teaching assistant. A
project group may appeal this judgment.
- Each entry will be tested on the entire collection of benchmark
programs generated by the project groups.
- The patterns will be run in the context of the standard A+ compiler.
- The winner is the entry that minimizes the combined code size
(number of bytes) of methods in the class benchmark programs as measured by
the
totalbytes script (to be provided).
- Finally, entries are only accepted until the beginning of week 12
at McGill.
The prizes for this year are to be determined. In the past, prizes were
Official dOvs Peephole Contest Winners' T-Shirts, one for each
member of the winning project group, and the T-shirts were presented to
the winners at the end of the course.
