- Abstract:
Automatic parallelization in the polyhedral model is based on affine
transformations from an original computation domain (iteration space) to a target
space-time domain, often with a different transformation for each
variable. Code generation, an often ignored step in this process that has a
significant impact on the quality of the final code. Previous methods of doing code generation are based on loop splitting, however they have non-optimal behavior when working in parameterized programs.
We have previously developed a general parameterized method for code generation based on dual representation of polyhedra. Here, we present a formal proof of correctness of the proposed method. We also discuss how our algorithm enables fine control over the tradeoff between code size and control overhead.
