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 |
|---|---|---|
|
Computes a matrix-matrix product with general matrices. |
|
|
Computes a matrix-matrix product where one input matrix is Hermitian and one is general. |
|
|
Performs a Hermitian rank-k update. |
|
|
Performs a Hermitian rank-2k update. |
|
|
Computes a matrix-matrix product where one input matrix is symmetric and one matrix is general. |
|
|
Performs a symmetric rank-k update. |
|
|
Performs a symmetric rank-2k update. |
|
|
Computes a matrix-matrix product where one input matrix is triangular and one input matrix is general. |
|
|
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.
