Distributed Linear Algebra from the Future

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[S,D,C,Z]POTRI | Inverse from Cholesky factor | ✔️ | ✔️ | ✔️ | | P[S,D,C,Z]TRTRI | Inverse of triangular matrix | ✔️ | ❌ | ❌ | | 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.

Getting started with DLAF

Build

See BUILD.md.

Link your program/library with DLAF

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:

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

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

```bash

By appending the value to the CMAKEPREFIXPATH

cmake -DCMAKEPREFIXPATH=${DLAFINSTALLPREFIX} ..

... or by setting DLAF_DIR

cmake -DDLAFDIR="$DLAFINSTALL_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

targetlinklibraries( PRIVATE DLAF::DLAF) ```

Documentation

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