Function Usage

Creates a handle to matrix-matrix multiplication. The data type of the input and output data is FLOAT16. After the handle is created, call aclopExecWithHandle to execute the operator.

Prototype

aclError aclblasCreateHandleForHgemm(aclTransType transA,
aclTransType transB,
aclTransType transC,
int m,
int n,
int k,
aclComputeType type,
aclopHandle **handle)

Parameters

Parameter	Input/Output	Description
transA	Input	Transpose flag of matrix A. For details about the type definition, see aclTransType.
transB	Input	Transpose flag of matrix B. For details about the type definition, see aclTransType.
transC	Input	Transpose flag of matrix C. Currently, the value can only be ACL_TRANS_N. For details about the type definition, see aclTransType.
m	Input	Number of rows in matrix A and matrix C.
n	Input	Number of columns in matrix B and matrix C.
k	Input	Number of columns in matrix A and number of rows in matrix B.
type	Input	Computation precision type (high precision by default). For details about the type definition, see aclComputeType.
handle	Output	Pointer to the operator execution handle's pointer. For details about the type definition, see aclopHandle.

Returns

0 on success; else, failure. For details, see aclError.
