Function

Obtains the heterogeneous networking mode of a given communicator.

Prototype

HcclResult HcclGetHeterogMode(HcclComm comm, HcclHeterogMode *mode)

Parameters

Parameter

Input/Output

Description

comm

Input

Communicator where the collective communication operation is performed.

The HcclComm type is defined as follows:

typedef void *HcclComm;

mode

Output

Heterogeneous mode.

For details about the HcclHeterogMode type, see HcclHeterogMode.

Returns

HcclResult: HCCL_SUCCESS on success, or else failure.

Restrictions

None

Example

HcclHeterogMode mode;
HcclResult ret = HcclGetHeterogMode(comm, &mode);
if (ret == HCCL_SUCCESS) {
    switch (mode) {
        case HCCL_HETEROG_MODE_HOMOGENEOUS:
            printf("Homogeneous networking\n");
            break;
        case HCCL_HETEROG_MODE_MIX_A2_A3:
            printf("A2/A3 heterogeneous networking\n");
