| integer(kind(rocblas_status_success)) function | rocblas_chemm_batched_ (handle, side, uplo, m, n, alpha, a, lda, b, ldb, beta, c, ldc, batch_count) |
Detailed Description
BLAS Level 3 API.
The hemm_batched functions perform a batch of the matrix-matrix operations:
C_i := alpha*A_i*B_i + beta*C_i if side == rocblas_side_left, C_i := alpha*B_i*A_i + beta*C_i if side == rocblas_side_right,
where alpha and beta are scalars, B_i and C_i are m by n matrices, and A_i is a Hermitian matrix stored as either upper or lower.
- Parameters
-
[in] handle - [rocblas_handle] handle to the rocBLAS library context queue. [in] side - [rocblas_side] - rocblas_side_left: C_i := alpha*A_i*B_i + beta*C_i
- rocblas_side_right: C_i := alpha*B_i*A_i + beta*C_i
[in] uplo - [rocblas_fill] - rocblas_fill_upper: A_i is an upper triangular matrix.
- rocblas_fill_lower: A_i is a lower triangular matrix.
[in] m - [rocblas_int] m specifies the number of rows of B_i and C_i. m >= 0. [in] n - [rocblas_int] n specifies the number of columns of B_i and C_i. n >= 0. [in] alpha alpha specifies the scalar alpha. When alpha is zero, then A_i and B_i are not referenced. [in] A - device array of device pointers storing each matrix A_i on the GPU. - A_i is m by m if side == rocblas_side_left.
- A_i is n by n if side == rocblas_side_right.
- Only the upper/lower triangular part is accessed.
- The imaginary component of the diagonal elements is not used.
[in] lda - [rocblas_int] lda specifies the first dimension of A_i. - If side = rocblas_side_left, lda >= max( 1, m ).
- Otherwise, lda >= max( 1, n ).
[in] B - device array of device pointers storing each matrix B_i on the GPU. Matrix dimension is m by n. [in] ldb - [rocblas_int] ldb specifies the first dimension of B_i. ldb >= max( 1, m ). [in] beta beta specifies the scalar beta. When beta is zero, then C_i need not be set before entry. [in] C - device array of device pointers storing each matrix C_i on the GPU. Matrix dimension is m by n. [in] ldc - [rocblas_int] ldc specifies the first dimension of C_i. ldc >= max( 1, m ). [in] batch_count - [rocblas_int] number of instances in the batch.
