cuSPARSELt: A High-Performance CUDA Library for Sparse Matrix-Matrix Multiplication
###################################################################################
**NVIDIA cuSPARSELt** is a high-performance CUDA library dedicated to general matrix-matrix operations in which at least one operand is a sparse matrix:
.. math::
D = Activation(\alpha op(A) \cdot op(B) + \beta op(C) + bias)
where :math:`op(A)/op(B)` refers to in-place operations such as transpose/non-transpose, and :math:`alpha, beta` are scalars or vectors.
The *cuSPARSELt APIs* allow flexibility in the algorithm/operation selection, epilogue, and matrix characteristics, including memory layout, alignment, and data types.
