//! Provides backend-agnostic BLAS operations for [Coaster][coaster]. //! //! BLAS (Basic Linear Algebra Subprograms) is a specification that prescribes a set of low-level //! routines for performing common linear algebra operations such as vector addition, scalar //! multiplication, dot products, linear combinations, and matrix multiplication. They are the de //! facto standard low-level routines for linear algebra libraries; the routines have bindings for //! both C and Fortran. Although the BLAS specification is general, BLAS implementations are often //! optimized for speed on a particular machine, so using them can bring substantial performance //! benefits. BLAS implementations will take advantage of special floating point hardware such as //! vector registers or SIMD instructions.<br/> //! [Source][blas-source] //! //! ## Overview //! //! A Coaster Plugin describes the functionality through three types of traits. //! //! * __PluginTrait__ -> IBlas<br/> //! This trait provides 'provided methods', which already specify the exact, backend-agnostic //! behavior of an Operation. These come in two forms `operation()` and `operation_plain()`, //! where the first takes care of full memory management and the later one just provides the computation //! without any memory management. In some scenarios you would like to use the plain operation for faster //! exection. //! //! * __BinaryTrait__ -> IBlasBinary<br> //! The binary trait provides the actual and potentially initialized Functions, which are able to compute //! the Operations (as they implement the OperationTrait). //! //! * __OperationTrait__ -> e.g. IOperationDot<br/> //! The PluginTrait can provide 'provided methods', thanks to the OperationTrait. The OperationTrait, //! has one required method `compute` which every Framework Function will implement on it's own way. //! //! Beside these traits a Coaster Plugin might also use macros for faster //! implementation for various Coaster Frameworks such as CUDA, OpenCL or common host CPU. //! //! Beside these generic functionality through traits, a Plugin also extends the Coaster Backend //! with implementations of the generic functionality for the Coaster Frameworks. //! //!
