Expand description
Sparse matrix-dense matrix multiplication (SpMM).
Computes C = alpha * A * B + beta * C where A is a sparse CSR matrix
and B, C are dense matrices.
§Strategy
Each warp processes one row of A and tiles across columns of B.
Within each row, the warp collaboratively loads non-zero entries and
accumulates partial sums into the output columns.
