QMCkl: Quantum Monte Carlo Kernel Library

Build Status

The domain of quantum chemistry needs a library in which the main kernels of Quantum Monte Carlo (QMC) methods are implemented. In the library proposed in this project, we expose the main algorithms in a simple language and provide a standard API and tests to enable the development of high-performance QMCkl implementations taking advantage of modern hardware.

See the source code to read the documentation.

To clone the repository, use:

git clone https://github.com/TREX-CoE/qmckl.git

Installation

The simplest way to obtain the source files of QMCkl is to download a source distribution. This particular repository is for maintainers, who write the kernels in org-mode files and produce the source code and the documentation from these files.

For maintainers

./autogen.sh
./configure --prefix=$PWD/_install

make
make check

For users

Obtain a source distribution and run

./configure 
make
make check
sudo make install
sudo make installcheck

Verificarlo CI

Since Verificarlo should not be a dependency of QMCkl, all Verificarlo functions are called only when the support is explicitely enabled (and ignored by the preprocessor otherwise). To enable vfc_ci support, the library should be configured with the following command :

./configure --prefix=$PWD/_install \ --enable-vfc_ci --host=x86_64 \ CC="verificarlo-f" FC="verificarlo-f"

where CC and FC are set to verificarlo-f, and support is explicitely enabled with the –enable-vfc_ci flag. Configuring the library with the “standard” command will cause all calls to Verificarlo related functions to be ignored, and the library will be built as usual.
