integer(c_int) function	hipblassgemmgroupedbatched_ (handle, transa_array, transb_array, m_array, n_array, k_array, alpha_array, aarray, lda_array, barray, ldb_array, beta_array, carray, ldc_array, group_count, group_size)

Detailed Description

BLAS Level 3 API.

The gemmGroupedBatched functions perform grouped batched matrix-matrix operations. There are group_count groups. Within group i, all problems share the same transA, transB, m, n, k, lda, ldb, ldc, alpha, and beta. Each group i contains group_size[i] problems. The total number of problems is problem_count = sum(group_size[i]).

For each problem j in group i:

C_j = alpha_i*op( A_j )*op( B_j ) + beta_i*C_j,

where op( X ) is one of

op( X ) = X      or
op( X ) = X**T   or
op( X ) = X**H.

Aarray, Barray, and Carray are device arrays of device pointers with length problem_count.

• Supported precisions in rocBLAS : s and d.
• Supported precisions in cuBLAS : not supported.

[in]	transB_array	- [const hipblasOperation_t*] host array of length group_count specifying op( B ) for each group.
[in]	m_array	- [const int*] host array of length group_count.
[in]	n_array	- [const int*] host array of length group_count.
[in]	k_array	- [const int*] host array of length group_count.
[in]	alpha_array	- device pointer or host pointer to an array of length group_count.
[in]	Aarray	- device array of device pointers storing each matrix A_j.
[in]	lda_array	- [const int*] host array of length group_count.
[in]	Barray	- device array of device pointers storing each matrix B_j.
[in]	ldb_array	- [const int*] host array of length group_count.
[in]	beta_array	- device pointer or host pointer to an array of length group_count.
[in,out]	Carray	- device array of device pointers storing each matrix C_j.
[in]	ldc_array	- [const int*] host array of length group_count.
[in]	group_count	- [int] number of groups.
[in]	group_size	- [const int*] host array of length group_count with the number of problems in each group.
