Queries the topology type of the current rank in the specified topology instance based on the given communicator and topology layer ID.

HcclResult HcclRankGraphGetTopoType(HcclComm comm, uint32_t netLayer, uint32_t topoInstId, CommTopo *topoType)

Parameter

Input/Output

Description

comm

Input

Communicator.

The HcclComm type is defined as follows:

typedef void *HcclComm;

netLayer

Input

Topology layer ID.

topoInstId

Input

Topology instance ID.

topoType

Output

Topology type:

For the definition of the CommTopo type, see CommTopo.

HcclResult: HCCL_SUCCESS on success, or else failure.

None

HcclComm comm;
CommTopo topoType;
HcclRankGraphGetTopoType(comm, netLayer=0, topoInstId=0, &topoType); // topoType=1 (1DMesh)
