[Question] How cusparse APIs are used in AMGx

Open Soujanyajanga opened this issue 2 years ago • 1 comments

Can you please let us know how cusparse API are getting leveraged by AMGx. Specifically what configurations (condition/criteria) needs to be met in the code flow for AMGx to use cusparse APIs.

Can you please recommend any specific test case that can be studied to understand the flow.

We use SpGEMM and SpMV extensively. I would recommend amgx_mpi_poisson7 as the simplest test case to do some profiling with.
