+The software is self optimising, trying several algorithms at run time and choosing the best performing one.  To achieve its high  computational speed latest version supports the [[SSE]] and [[AVX]] instructions of the latest x86-processors.  The library provides a native [[C]]-API.  In [[Fortran]]-2003 this is easily accessed using the C-bindings which are part of the language standard.  For older versions of Fortran the library also contains a Fortran interface.  To avoid data alignment issues, which could inhibit the performance, using the Fortran-2003 bindings to the C-API is encouraged.
-The library contains parallel versions using either of [[pthreads]], [[OpenMP]] or [[MPI]].  Besides the current version 3.x, there is the older version 2.x, which have different application interfaces.  It is not recommended to use version 2.x for new developments, however it is still widely used in legacy code.
