# The following 3rd party direct linear solvers are supported:
# - Pardiso (multi-threaded - OMP)
# - IntelPardiso (multi-threaded - OMP)
# - SuperLU (sequential)
# - SuperLU_MT (multi-threaded - pthreads, OMP)
# - Trilinos Amesos (sequential): Klu, SuperLU, Lapack, Umfpack
# If you are using Pardiso or IntelPardiso solvers you have to export their bin directories,
# using, for instance, LD_LIBRARY_PATH shell variable (for more details see their documentation).
# If you are using OpenMP capable solvers you should set the number of threads
# (typically to the number of cores), for instance:
# export OMP_NUM_THREADS=4
# or if using IntelPardiso solver:
# export MKL_NUM_THREADS=24
# You can place the above command at the end of $HOME/.bashrc (or type it in shell, before simulation).
# Import desired solver module (uncomment it from below) and set it using SetLASolver function:
