Good day, everyone! I run an example, and get below amgx exception:

Hi. Apologies, the mixed precision solver option has been disabled for some time now.

We are always open to revisiting that, but in the past few years it has not been something that has been raised as a priority.

Thanks!

Is it possible to implement my own mixed precision PCG/FGMRES solver by using AMGX as the preconditioner? Reference papers or examples or ideas are appreciated !
