DLA-Future is a distributed linear algebra library implemented using C++ std::execution P2300 which provides:

• an asynchronous C++ interface,
• a synchronous C interface,
• a synchronous ScaLAPACK-like C interface (ScaLAPACK drop-in with a subset of ScaLAPACK arguments. E.g. workspace arguments are not present),
• a synchronous ScaLAPACK-like Fortran interface (See DLA-Future-Fortran).

DLA-Future runs on x86 and ARM CPUs as well as NVIDIA and AMD GPUs.

Currently DLA-Future provides the following algorithms which are available in the following interfaces:

Notes:

• The C++ interface provides a non distributed interface as well.

See BUILD.md.

Using DLAF in a CMake project is extremely easy!

In the following, the variable DLAF_INSTALL_PREFIX is set to where DLAF is installed. In case you used spack for installing DLAF, you can easily set it with:

export DLAF_INSTALL_PREFIX=`spack location -i dla-future`

Then, you can configure your project with one of the following:

# By appending the value to the CMAKE_INSTALL_PREFIX
cmake -DCMAKE_INSTALL_PREFIX=${DLAF_INSTALL_PREFIX} ..

# ... or by setting DLAF_DIR
cmake -DDLAF_DIR="$DLAF_INSTALL_PREFIX/lib/cmake" ..

Then, it is just as simple as adding these directives in your CMakeLists.txt:

find_package(DLAF)
# ... and then for your executable/library target
target_link_libraries(<your_target> PRIVATE DLAF::DLAF)

• Documentation of master branch
• Documentation of v0.6.0

See DOCUMENTATION.md for the documentation of older versions, or for the instructions to build it.
