BLAS Level 3 Routines
BLAS Level 3 routines perform matrix-matrix operations. The following
table lists the BLAS Level 3 routine groups and the data types
associated with them.
Routine Group | Data Types | Description |
|---|---|---|
std::int8_t , oneapi::mkl::bfloat16 , sycl::half , float , double , std::complex<float> , std::complex<double> , mixed | Computes a matrix-matrix product with general matrices. | |
std::complex<float> , std::complex<double> | Computes a matrix-matrix product where one input matrix is Hermitian and one is general. | |
float , double , std::complex<float> , std::complex<double> | Computes a matrix-matrix product where one input matrix is symmetric and one matrix is general. | |
float , double , std::complex<float> , std::complex<double> | Computes a matrix-matrix product where one input matrix is triangular and one input matrix is general. | |
float , double , std::complex<float> , std::complex<double> | Solves a triangular matrix equation (forward or backward solve). |
The BLAS functions are blocked where possible to restructure the
code in a way that increases the localization of data reference,
enhances cache memory use, and reduces the dependency on the
memory bus.
The code is distributed across the processors to maximize
parallelism.
