+# AMG4PSBLAS  v1.2
+Algebraic Multigrid Package  based on [PSBLAS](https://github.com/sfilippone/psblas3) (Parallel Sparse BLAS version 3.9)
 
----------------------------------------------------------------------
+AMG4PSBLAS is a package of parallel algebraic multilevel preconditioners included in the PSCToolkit (Parallel Sparse Computation Toolkit) software framework.
 
-AMG4PSBLAS is a package of Algebraic MultiGrid (AMG)
-preconditioners for  the iterative solution of large and sparse linear systems.
+It is a progress of a software development project started in 2007, named MLD2P4, which originally implemented a multilevel version of some domain decomposition preconditioners of additive-Schwarz type and was based on a parallel decoupled version of the well known smoothed aggregation method to generate the multilevel hierarchy of coarser matrices.
 
-It is an evolution of MLD2P4 (see LICENSE.MLD2P4), but it has been
-thoroughly reworked, and it is sufficiently different to warrant a new
-project name.
+In the last years the package was extended for including new algorithms and functionalities for the setup and application new AMG preconditioners with the final aims of improving efficiency and scalability when tens of thousands cores are used and of boosting reliability in dealing with general symmetric positive definite linear systems.
 
+It is an evolution of MLD2P4 (see [LICENSE.MLD2P4](LICENSE.MLD2P4)), but due to the significant number of changes and the increase in scope, we decided to rename the package as AMG4PSBLAS.
 
-MAIN REFERENCES:
+AMG4PSBLAS has been designed to provide scalable and easy-to-use preconditioners in the context of the PSBLAS (Parallel Sparse Basic Linear Algebra Subprograms) computational framework and can be used in conjuction with the Krylov solvers available in this framework. Our package is based on a completely algebraic approach; therefore users level interfaces assume that the system matrix and preconditioners are represented as PSBLAS distributed sparse matrices.
 
-     
+AMG4PSBLAS enables the user to easily specify different features of an algebraic multilevel preconditioner, thus allowing to experiment with different preconditioners for the problem and parallel computers at hand.

+The package employs object-oriented design techniques in Fortran 2008, with interfaces to additional third party libraries such as MUMPS, UMFPACK, SuperLU, and SuperLU_Dist, which can be exploited in building multilevel preconditioners. The parallel implementation is based on a Single Program Multiple Data (SPMD) paradigm; the inter-process communication is based on MPI and is managed mainly through PSBLAS.

+## Installing
+
+Installation requires having a working version of the [PSBLAS](https://github.com/sfilippone/psblas3) library installed.
+AMG4PSBLAS has several interfaces to third-party libraries that can be used in the construction and application phases of preconditioners. 
+In particular, it is possible to link AMG4PSBLAS with the libraries: MUMPS, SuperLU, SuperLU_Dist, UMFPACK. This is _not mandatory_ and the library can run 
+in isolation and without these features.
 
 0. Unpack the tar file in a directory of your choice (preferrably
    outside the main PSBLAS directory).
-1. run configure --with-psblas=<ABSOLUTE path of the PSBLAS install directory>
+1. run configure `--with-psblas=<ABSOLUTE path of the PSBLAS install directory>`
    adding the options for MUMPS, SuperLU, SuperLU_Dist, UMFPACK as desired.
-   See MLD2P4 User's and Reference Guide (Section 3) for details.
-2. Tweak Make.inc if you are not satisfied.
-3. make; 
+   See [AMG4PSBLAS User's and Reference Guide](docs/amg4psblas_1.0-guide.pdf) (Section 3) for details.
+2. Tweak `Make.inc` if you are not satisfied.
+3. run `make`; 
 4. Go into the test subdirectory and build the examples of your choice.
-5. (if desired): make install 
+5. (if desired): `make install` 
 
+>[!CAUTION]
+>The single precision version is supported only by MUMPS and SuperLU;
+>thus, even if you specify at configure time to use UMFPACK or SuperLU_Dist,
+>the corresponding preconditioner options will be available only from
+>the double precision version.
 
-NOTES
+### CUDA, OpeMP, OpenACC
 
-- The single precision version is supported only by MUMPS and SuperLU;
-  thus, even if you specify at configure time to use UMFPACK or SuperLU_Dist, 
-  the corresponding preconditioner options will be available only from
-  the double precision version.
+CUDA, OpenMP and OpenACC features are transparently inherited by PSBLAS installation. If PSBLAS has been configured (and installed) with these supports then AMG4PSBLAS will transparently inherit them. It will then be possible to move the computation to GPU accelerator simply by selecting the appropriate variable types. If these have not been activated or installed for PSBLAS then they will not be available for AMG4PSBLAS either and the operation will be purely on CPU/MPI. See also the samples/cuda folder.

+In the European project “Energy oriented Center of Excellence: toward exascale for energy” we made available a software as service portal: [https://eocoe.psnc.pl/](https://eocoe.psnc.pl/). This permits to test several cutting-edge computational methods for accelerating the transition to the production, storage and management of clean, decarbonized energy. Among them you have the possibility of running PSBLAS+AMG4PSBLAS on some test problems to become familiar with using the software.

-  !   parms        -  type(amg_RTml_parms)

-  !                   Pointer (really a pointer!) to the local part of the current 
-  !                   matrix (so we have a unified treatment of residuals).
-  !                   We need this to avoid passing explicitly the current matrix
-  !                   to the routine which applies the preconditioner.

-  !                   Pointer to the communication descriptor associated to the
-  !                   matrix pointed by base_a.
-  !   map          -  Stores the maps (restriction and prolongation) between the
-  !                   vector spaces associated to the index spaces of the previous
-  !                   and current levels.
-  !
-  !   Methods:  
-  !     Most methods follow the encapsulation hierarchy: they take whatever action
-  !     is appropriate for the current object, then call the corresponding method for
-  !     the contained object.
-  !     As an example: the descr() method prints out a description of the
-  !     level. It starts by invoking the descr() method of the parms object,
-  !     then calls the descr() method of the smoother object. 
-  !
-  !    descr      -   Prints a description of the object.
-  !    default    -   Set default values
-  !    dump       -   Dump to file object contents
-  !    set        -   Sets various parameters; when a request is unknown
-  !                   it is passed to the smoother object for further processing.
-  !    check      -   Sanity checks.

-  !   ac           -  The local part of the current-level matrix, built by
-  !                   coarsening the previous-level matrix.
-  !   desc_ac      -  type(psb_desc_type).
-  !                   The communication descriptor associated to the matrix
-  !                   stored in ac.
-  !   base_a       -  type(psb_Tspmat_type), pointer.
-  !                   Pointer (really a pointer!) to the local part of the current 
-  !                   matrix (so we have a unified treatment of residuals).
-  !                   We need this to avoid passing explicitly the current matrix
-  !                   to the routine which applies the preconditioner.

-  !                   Pointer to the communication descriptor associated to the
-  !                   matrix pointed by base_a.
-  !   map          -  Stores the maps (restriction and prolongation) between the
-  !                   vector spaces associated to the index spaces of the previous
-  !                   and current levels.
-  !
-  !   Methods:  
-  !     Most methods follow the encapsulation hierarchy: they take whatever action
-  !     is appropriate for the current object, then call the corresponding method for
-  !     the contained object.
-  !     As an example: the descr() method prints out a description of the
-  !     level. It starts by invoking the descr() method of the parms object,
-  !     then calls the descr() method of the smoother object. 
-  !
-  !    descr      -   Prints a description of the object.
-  !    default    -   Set default values
-  !    dump       -   Dump to file object contents
-  !    set        -   Sets various parameters; when a request is unknown
-  !                   it is passed to the smoother object for further processing.
-  !    check      -   Sanity checks.
-  !    sizeof     -   Total memory occupation in bytes
-  !    get_nzeros -   Number of nonzeros

+!  This module defines:

+!    smoother for a Jacobi/block Jacobi smoother.
+!  The smoother stores in ND the block off-diagonal matrix.
+!  One special case is treated separately, when the solver is DIAG or L1-DIAG
+!  then the ND is the entire off-diagonal part of the matrix (including the
+!  main diagonal block), so that it becomes possible to implement
+!  a pure Jacobi or L1-Jacobi global solver.

+! Module: amg_d_poly_smoother_mod
+!
+!  This module defines:
+!    the amg_d_poly_smoother_type data structure containing the
+!    smoother for a Jacobi/block Jacobi smoother.
+!  The smoother stores in ND the block off-diagonal matrix.
+!  One special case is treated separately, when the solver is DIAG or L1-DIAG
+!  then the ND is the entire off-diagonal part of the matrix (including the
+!  main diagonal block), so that it becomes possible to implement
+!  a pure Jacobi or L1-Jacobi global solver.

-  !   parms        -  type(amg_RTml_parms)

-  !                   The communication descriptor associated to the matrix

-  !                   Pointer (really a pointer!) to the local part of the current 
-  !                   matrix (so we have a unified treatment of residuals).
-  !                   We need this to avoid passing explicitly the current matrix

-  !                   matrix pointed by base_a.
-  !   map          -  Stores the maps (restriction and prolongation) between the

-  !                   and current levels.
-  !
-  !   Methods:  
-  !     Most methods follow the encapsulation hierarchy: they take whatever action
-  !     is appropriate for the current object, then call the corresponding method for
-  !     the contained object.
-  !     As an example: the descr() method prints out a description of the
-  !     level. It starts by invoking the descr() method of the parms object,
-  !     then calls the descr() method of the smoother object. 
-  !
-  !    descr      -   Prints a description of the object.
-  !    default    -   Set default values
-  !    dump       -   Dump to file object contents
-  !    set        -   Sets various parameters; when a request is unknown
-  !                   it is passed to the smoother object for further processing.
-  !    check      -   Sanity checks.
-  !    sizeof     -   Total memory occupation in bytes
-  !    get_nzeros -   Number of nonzeros

+! Module: amg_s_poly_smoother_mod
+!
+!  This module defines:
+!    the amg_s_poly_smoother_type data structure containing the
+!    smoother for a Jacobi/block Jacobi smoother.
+!  The smoother stores in ND the block off-diagonal matrix.
+!  One special case is treated separately, when the solver is DIAG or L1-DIAG
+!  then the ND is the entire off-diagonal part of the matrix (including the
+!  main diagonal block), so that it becomes possible to implement
+!  a pure Jacobi or L1-Jacobi global solver.

-  !   sm           -  class(amg_T_base_smoother_type), allocatable

-  !   parms        -  type(amg_RTml_parms)

-  !                   The communication descriptor associated to the matrix

-  !                   Pointer (really a pointer!) to the local part of the current 
-  !                   matrix (so we have a unified treatment of residuals).
-  !                   We need this to avoid passing explicitly the current matrix
-  !                   to the routine which applies the preconditioner.

-  !                   Pointer to the communication descriptor associated to the
-  !                   matrix pointed by base_a.
-  !   map          -  Stores the maps (restriction and prolongation) between the
-  !                   vector spaces associated to the index spaces of the previous
-  !                   and current levels.
-  !
-  !   Methods:  
-  !     Most methods follow the encapsulation hierarchy: they take whatever action
-  !     is appropriate for the current object, then call the corresponding method for
-  !     the contained object.
-  !     As an example: the descr() method prints out a description of the
-  !     level. It starts by invoking the descr() method of the parms object,
-  !     then calls the descr() method of the smoother object. 
-  !
-  !    descr      -   Prints a description of the object.
-  !    default    -   Set default values
-  !    dump       -   Dump to file object contents
-  !    set        -   Sets various parameters; when a request is unknown
-  !                   it is passed to the smoother object for further processing.
-  !    check      -   Sanity checks.
-  !    sizeof     -   Total memory occupation in bytes
-  !    get_nzeros -   Number of nonzeros
