LinearSolve solvers
In this page, we list several recommended solvers provided by LinearSolve.jl for solving steadystate and spectrum in hierarchical equations of motion approach.
Remember to import LinearSolve.jl
using LinearSolve(click here to see the full solver list provided by LinearSolve.jl)
UMFPACKFactorization (Default solver)
This solver performs better when there is more structure to the sparsity pattern (depends on the complexity of your system and baths).
UMFPACKFactorization()KLUFactorization
This solver performs better when there is less structure to the sparsity pattern (depends on the complexity of your system and baths).
KLUFactorization()A generic BICGSTAB implementation from Krylov
KrylovJL_BICGSTAB()Pardiso
This solver is based on Intel openAPI Math Kernel Library (MKL) Pardiso
Using this solver requires adding the package Pardiso.jl, i.e. using Pardiso
using Pardiso
using LinearSolve
MKLPardisoFactorize()
MKLPardisoIterate()
