REVERSE AUGMENTED OVERVIEW

NOTE: Before using this driver, the user must install the Chronos package and activate its license. In order to download and install Chronos, please contact the developer team by using the form provided at DEMO_Chronos

This package is composed by the following directories:

Drivers contains the source codes (c++) of the Driver_Lagrange, the Reverse Augmented Constraint preconditioner and the Saddle Point matrix classes.

Chronos is the symbolic link to the INSTALL directory of the the linear solver package (version 1.0).

ExternalLib is the symbolic link to the the external libraries necessary for Chronos:

• lapack lapack package (version 3.8.0).

• parmetis metis package (version 4.0.3).

• pugixml pugixml package (version 11.1).

• jwt-cpp A header only library for creating and validating json web tokens in c++ (version 0.5.0).

• curlpp C++ wrapper around libcURL (version 0.8.1).

• LexActivator interface for Chronos with LexActivator package (https://docs.cryptlex.com/changelog/lexactivator).

Both the INSTALL and the ExternalLib directories are provided in the Chronos installation package.

Binary contains scripts (bash) to compile the driver.

Benchmarks contains the examples used for the validation of the code.

TO COMPILE

- REQUIRED PACKAGES

cmake 3.10.2, GNU 7.5.0, OMP 4.5, MPI 3.1

- COMPILE DRIVER

Create directories to store binary file in Binary directory:

mkdir Driver_Lagrange

Run scripts in Binary directory:

./run_cmake
./run_make

- COMPILE DRIVER AFTER MINOR CHANGES

Run script in the Binary directory:

./run_make

- COMPILE DRIVER AFTER MAJOR CHANGES

Run scripts in the Binary directory:

./rm_binary
./run_cmake
./run_make

TO RUN THE BENCHMARK

The executable driver_Lagrange is located at the path ./Binary/Driver_Lagrange/src/Core/driver_Lagrange.

Move to ./Benchmarks/TestLagrange/ directory and extract the matrices from the archive with the following bash command:

tar -xvf mat.tar.gz

Finally, run the script with ./RUN in order to test the program.
