Details of the hypergraph:
Center hyperedge (induced by source paper "a unified iteration space transformation framework for sparse and dense tensor algebra"):
  Abstract: We address the problem of optimizing mixed sparse and dense tensor algebra in a compiler. We show that standard loop transformations, such as strip-mining, tiling, collapsing, parallelization and vectorization, can be applied to irregular loops over sparse iteration spaces. We also show how these transformations can be applied to the contiguous value arrays of sparse tensor data structures, which we call their position space, to unlock load-balanced tiling and parallelism. #R##N#We have prototyped these concepts in the open-source TACO system, where they are exposed as a scheduling API similar to the Halide domain-specific language for dense computations. Using this scheduling API, we show how to optimize mixed sparse/dense tensor algebra expressions, how to generate load-balanced code by scheduling sparse tensor algebra in position space, and how to generate sparse tensor algebra GPU code. Our evaluation shows that our transformations let us generate good code that is competitive with many hand-optimized implementations from the literature.
