Matrix format support for DSS solver

Meng__Xiangyi — Sat, 30 Nov 2019 10:57:52 GMT

Hello!

I know PARDISO solver supports both CSR and BSR sparse matrix format, but what format does DSS solver support? Only CSR?

And what are the other differences between PARDISO and DSS solver? If I want to solve a sparse linear system using direct method, which solver is recommended? PARDISO or DSS?

Thanks in advance for reply!
