Semi-automatic Generation of Parallelizable Patterns From Source Code Examples

Generation of program patterns from source code is a difficult, time consuming and error-prone process when performed by programmers. We describe an implemented system which generates patterns from an abstract syntax tree with interaction by the user. Our approach is based on creating intermediate pattems by exploring d.m dependencies in the source code and allowing the user to change andor eliminate parts of it in order to create a final pattern. We describe the architecture of our system as well as the pattem language used, and illustrate our upproach with examples. 1
