Detailed Description

Materialize compact GPU reduction partials and their SDFG accesses.

Uses ReductionBufferAnalysis to declare private/shared arrays, record schedule buffer references, and pack body memlets while retaining original writeback indices. Initialization, combination, and publication remain in GPU codegen. Existing valid materializations are checked and left unchanged.

Member Function Documentation

name()

std::string sdfg::passes::ReductionSharedMemoryDelinearization::name ( )

overridevirtual

Returns

"ReductionSharedMemoryDelinearization".

Implements sdfg::passes::Pass.

run_pass()

bool sdfg::passes::ReductionSharedMemoryDelinearization::run_pass ( builder::StructuredSDFGBuilder & builder, analysis::AnalysisManager & analysis_manager )

overridevirtual

Validate ownership and placement, then materialize pending GPU reductions.

Invalidates all analyses after rewriting the graph.

Returns

true if new buffers/accesses were materialized; false if none were pending.

Exceptions

InvalidSDFGException

for unsupported footprints or incompatible buffer declarations/ownership.

Reimplemented from sdfg::passes::Pass.
