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:
| ScaLAPACK Name | Algorithm | C++ API | C API | Scalapack C API |
|---|---|---|---|---|
P[S,D,C,Z]TRMM |
Triangular Matrix Multiplication | ✔️ | ❌ | ❌ |
P[C,Z]HEMM, P[S,D]SYMM |
Hermitian Matrix Multiplication | ✔️ | ❌ | ❌ |
P[S,D,C,Z]TRSM |
Triangular Solver | ✔️ | ❌ | ❌ |
P[S,D,C,Z]POTRF |
Cholesky Decomposition | ✔️ | ✔️ | ✔️ |
P[C,Z]HEEV*, P[S,D]SYEV* |
Symmetric / Hermitian eigenvalue solver | ✔️ | ✔️ | ✔️ |
P[C,Z]HEGV*, P[S,D]SYGV* |
Generalized Symmetric / Hermitian eigenvalue solver | ✔️ | ✔️ | ✔️ |
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_PREFIX_PATH
cmake -DCMAKE_PREFIX_PATH=${DLAF_INSTALL_PREFIX} ..
# ... or by setting DLAF_DIR
cmake -DDLAF_DIR="$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)
See DOCUMENTATION.md for the documentation of older versions, or for the instructions to build it.
