LCT-AUX by M. Iazzi, combined with ALPSCore

This branch is using ALPSCore for MPI parallelization of the LCT-AUX code of M. Iazzi (https://gitlab.phys.ethz.ch/iazzi/lct-aux).

Install

Here we switched to the CMake building framework. The code can be compile running the following:

mkdir build && cd build
cmake ..
make
make install

Finding dependencies

The code depends on

• Eigen3
• Lua
• ALPSCore (with MPI support)
• (optional) Intel MKL

Here are some variable that can be set when the dependencies are not in the stadard locations.

Eigen3 Here we use pkg-config to find the include path. Make sure to have the directory containing eigen3.pc in the pkg-config path. One can add more search directories for pkg-config with the environment variable export PKG_CONFIG_PATH=/path/to/eigen/share/pkgconfig:$PKG_CONFIG_PATH.

Lua Set the environment variable export LUA_DIR=/path/to/lua/root to the root of the Lua installation.

ALPSCore Set the environment variable export ALPSCore_DIR=/path/to/alpscore/root to the root of the ALPSCore installation.

CMake options

Here are some useful CMake options that can be set during the configuration

cmake -DOPTION=VALUE ..

or later with the CMake interactive interface ccmake .

• ENABLE_MKL (ON / OFF) : Whether to enable MKL support in Eigen or not
• CMAKE_BUILD_TYPE (Release / Debug / RelWithDebInfo): Which kind of build
• CMAKE_INSTALL_PREFIX (PATH) : where to install

Special installation

The directory build_examples contains example for building the code and its dependencies on special platforms, e.g. on supercomputers or clusters using the module system.
