Introduction

rocSPARSE is a library that contains basic linear algebra subroutines for sparse matrices and vectors written in HIP for GPU devices. It is designed to be used from C and C++ code. The functionality of rocSPARSE is organized in the following categories:

• Sparse Auxiliary Functions describe available helper functions that are required for subsequent library calls.

• Sparse Level 1 Functions describe operations between a vector in sparse format and a vector in dense format.

• Sparse Level 2 Functions describe operations between a matrix in sparse format and a vector in dense format.

• Sparse Level 3 Functions describe operations between a matrix in sparse format and multiple vectors in dense format.

• Sparse Extra Functions describe operations that manipulate sparse matrices.

• Sparse Preconditioner Functions describe manipulations on a matrix in sparse format to obtain a preconditioner.

• Sparse Conversion Functions describe operations on a matrix in sparse format to obtain a different matrix format.

• Sparse Reordering Functions describe operations on a matrix in sparse format to obtain a reordering.

• Sparse Utility Functions describe routines useful for checking sparse matrices for valid data
