Here is a list of all documented modules with brief descriptions:

Mcontrol	This module handles the calculation of the acceptance ratio. It also monitors the precision of the code, as well as the timing
Ndefault_parameters_generic
Mfields_mod	Handles Hubbard Stratonovitch fields
Mglobal_mod	Handles global updates and parallel tempering
Mhamiltonian	This module defines the Hamiltonian and observables. Here, we have included a set of predefined Hamiltonians. They include the Hubbard and SU(N) tV models on honeycomb, pi-flux and square lattices
Mhamiltonian_main	This module defines the interface between the Hamiltonians (= model and observables definition) and the Monte Carlo core. Hamiltonians are defined as submodules of this module. The Monte Carlo core has only access to public members of this module. For defining a new Hamiltonian named <new_ham_name>, the user has to create the file Hamiltonians/Hamiltonian_<new_ham_name>_smod.F90 and add the line <new_ham_name> to Hamiltonians.list
Mhop_mod	This module computes and stores the exponential of the hopping matrix. It also provide routines to carry out multiplications with \( e^{ - \Delta \tau H_t } = \prod_{n=1}^{N} e^{ - \Delta \tau_n H_t(n) } \), \( e^{ \Delta \tau H_t } = \prod_{n=N}^{1} e^{ \Delta \tau_n H_t(n) } \), \( e^{ - \Delta \tau H_t/2 } = \prod_{n=1}^{N} e^{ - \Delta \tau_n H_t(n)/2 } \), and \( e^{ \Delta \tau H_t/2 } = \prod_{n=N}^{1} e^{ \Delta \tau_n H_t(n)/2 } \). The last equality are important for the symmetric Trotter option. (See variable: Symm in the Hamiltonian module)
Mlattices_interface	C Interface for creating lattice. For use in pyALF
Mlrc_mod	This module handles the long range Coulomb repulsion
Mmpi_shared_memory	This module provides an interface to allocate memory that is shared between different MPI jobs from a single communicator on the same node
Mmymats	Wrappers for linear algebra
Mobservables	This module defines the Obser_Vec and Obser_Latt types and provides routine to initialize them and to print out the bins
Moperator_mod	Defines the Operator type, and provides a number of operations on this type
Nparse_ham
Nparse_ham_mod
Mpredefined_hoppings	This module provides a set of predefined hoppings as well as a general framework to specify the hopping matrix for translation invariant multi-orbital systems
Mpredefined_int	This module provides a set of predefined interactions
Mpredefined_lattices	This module provides a set of predefined lattices
Mpredefined_obs	This module provides a set of predefined observables
Mpredefined_trial	This module provides a set of predefined trial wave functions
Mqdrp_mod	This constructs a decompostion Mat = Q D R P^* using a pivoted QR decomposition
Mtau_m_mod	This module handles calculation of imagimary time displaced Green functions and calls the routine ObserT.F90 in the Hamiltonian module, so as to compute the defined time dispalced correlations functions. This modules is for the finite temperature code
Mtau_p_mod	This module handles calculation of imaginary-time-displaced Green functions and calls the routine ObserT.F90 in the Hamiltonian module, so as to compute user defined time-displaced correlations functions. This module is for the projector code
Mudv_state_mod	Handles UDV decompositions
Mudv_wrap_mod	This module contains two version of the stabilization. To switch between the two schemes you should define STAB1 in the set_env.sh file. The defaut scheme is quick and gernerically works better
Mwavefunction_mod	Defines the wavefunction type
Mwrapgr_mod	Handles global updates on a single time slice
