Verified ATL Scheduling Framework

This repository contains the implementation and demonstrations of the verified ATL user-scheduling framework.

To build the framework, simply run make in the src directory.

The C code generated from our set of examples can be found in src/clib. It can also be regenerated by running make clib from src.

For a set of simple programs and proofs to walk through please see:

• pipeline_schedule in src/Blur.v. This is a walkthrough of the scheduling proof for the example in the introduction of our paper.
• scatter_gather in src/GatherScatter.v. This is a walkthrough of the scheduling proof for the scatter-to-gather transformation mentioned in the evaluation section of our paper.
• equiv in src/Im2col.v. This is a walkthrough of im2col transformation outlined in the evaluation section of our paper.

For the full-scale proof constructing the tiled blur performance evaluation example, please see total_fusion_to_tiled in src/Blur.v.
