-AMG4PSBLAS is a package of parallel algebraic multilevel preconditioners included in the PSCToolkit (Parallel Sparse Computation Toolkit) software framework.
+AMG4PSBLAS is a package of parallel algebraic multilevel preconditioners included in
+the PSCToolkit (Parallel Sparse Computation Toolkit) software framework.
 
-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.

+smoothed aggregation method to generate the multilevel hierarchy of coarser matrices. 
 
-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.

-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.

+## CMAKE 
+AMG4PSBLAS supports building with CMake. To configure the project, you must explicitly provide the path where PSBLAS is installed. If this path is not specified, the configuration will fail with a fatal error.
+
+From the root directory of the project, run:
+### 1. Create and enter the build directory
+```
+mkdir build
+cd build
+```
+
+### 2. Configure the project (MANDATORY: specify your PSBLAS path)
+```
+cmake -DPSBLAS_INSTALL_DIR=</path/to/psblas/installation> ..
+```
+During this step, CMake will:
+- Search for the PSBLAS package in the provided path.
+- Detect and configure MPI (required for C, C++, and Fortran).
+- Set up include and module directories based on the PSBLAS configuration.
+- Configure integer sizes (IPK and LPK) to match the PSBLAS installation.
+### 2.1. Customizing the Installation Path
+By default, the library will be installed in standard system locations. To install amg4psblas in a custom directory, use the CMAKE_INSTALL_PREFIX variable:
+```
+cmake -DPSBLAS_INSTALL_DIR=</path/to/psblas/installation> \
+      -DCMAKE_INSTALL_PREFIX=</path/to/amg4psblas_install> ..
+```
+
+### 3. Compiling and Installing
+Once configured, you can build the libraries (amg_prec and amg_cbind) and install them.
+#### Build the library
+```
+make
+```
+
+#### Install the library, modules, and samples
+```
+make install
+```
+
+
 ### CUDA, OpeMP, OpenACC
 
-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.

 ### EoCoE - Software as service portal
 
-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.

+## MPI and Compilers
+ The library has been successfully compiled and tested with the same  compilers
+ and MPI implementations as PSBLAS 3.9, which include:
+ - MPICH 4.2.3, 4.3.0, 4.3.2
+ - OpenMPI 4.1.8. 5.0.7, 5.0.8, 5.0.9
+ 
+ combined with
+ 
+ - GNU compilers 10.5.0, 11.5.0, 12.5.0, 13.3.0, 14.2.0 14.3.0, 15.2.0
+ - LLVM  20.1.0 and 21.1.0 (except OpenMPI 4.1.8 which does not build with LLVM)
+ 
+ Moreover, it has been tested with the Intel OneAPI toolchain versions 2025.2 and 2025.3
+
+ As of this release, the NVIDIA compiler 25.7 fails to handle our code.
+ Cray, IBM and NAg compilers have been used for testing in the past, but not on this version.
