MATSEQAIJHIPSPARSE

MATAIJHIPSPARSE = “(seq)aijhipsparse” - A matrix type to be used for sparse matrices on AMD GPUs A matrix type whose data resides on AMD GPUs. These matrices can be in either CSR, ELL, or Hybrid format. All matrix calculations are performed on AMD/NVIDIA GPUs using the HIPSPARSE library.

Options Database Keys

• -mat_type aijhipsparse - sets the matrix type to MATSEQAIJHIPSPARSE

• -mat_hipsparse_storage_format csr - sets the storage format of matrices (for MatMult() and factors in MatSolve()). Other options include ell (ellpack) or hyb (hybrid).

• -mat_hipsparse_mult_storage_format csr - sets the storage format of matrices (for MatMult()). Other options include ell (ellpack) or hyb (hybrid).

• -mat_hipsparse_use_cpu_solve - Do MatSolve() on the CPU
