Solv_AMG

#include <Solv_AMG.h>

AMD solver wrapper to switch to the more robust/performant AMG preconditioner on CPU/GPU Nvidia/GPU AMD and have datafile unicity, as changing solver/preconditioner for different architecture is painful.

readOn

Entree & Solv_AMG::readOn(Entree &) override

Reads the configuration for the AMG solver from the input stream.

This function parses the input stream to configure the AMG solver parameters, including the relative tolerance (RTOL), absolute tolerance (ATOL), and whether to print additional information (IMPR). It supports different solver libraries based on the available hardware (CPU or GPU). The expected input format is: amg solver { rtol value [impr] }
