Symmetry exploitation in cuDSS

Accelerated Computing GPU-Accelerated Libraries

HI
Have been using CUDA cuDSS from the simple example provided and think it is fantastic library.

Was wondering if exploitation can be taken of matrix if it is symmetric to get even faster execution?

Cheers
Terry

Hi, please see cuDSS Data Types — NVIDIA cuDSS documentation if matrix is symmetric or symmetric positive defined and cuDSS Data Types — NVIDIA cuDSS documentation to specify which triangular to be use. Note that cudssMatrixViewType_t defines what part of the matrix will be used. For example if CUDSS_MVIEW_LOWER is set then cudss will ignore all matrix indexes and values from upper part

Thank you Antona, it has taken a few days to go through the documentation and examples your hints above were fantastic.
