Give COO, Laplacian, symmetrization and sparse helper templates independent CUDA owners, reusing existing map, scan and lower shared dispatch.
Register every sparse helper matrix, generate the COO kernel declarations before their consumers, and give shared masked-matrix, Laplacian-map, and CUB-merge kernels canonical owners.
The existing
generate_inst_matrixexpands ordinary JSON matrices directly into separate.cufiles, with one concrete owning instantiation per generated translation unit. Launcher declarations stay in headers; host definitions and the corresponding device kernels stay in CUDA sources. Shared lower kernels have their own owners.Prerequisites: #2937, #2906, #2913, #2921, #2938.
Diff against this PR’s parent: 40 files, +1601/−52 lines.
Validation: native JSON/CMake generation checked on this exact branch and its dependency closure; each generated owner has one owning instantiation. Complete-library builds, device-kernel census, and focused runtime checks are tracked in #2888.
Binary savings: the previous figures measured the grouped-owner implementation and are retired for this revised layout. Per-PR CUDA 12.9 and 13.3 complete-library remeasurement is pending; increased fatbin-container overhead means the old figures must not be carried forward.
