Function

Sets the number of BatchWrite communication queues on each core that delivers tasks to the server.

Prototype

uint32_t SetQueueNum(uint16_t num)

Parameters

**Table 1** Parameters
Parameter	Input/Output	Description
num	Input	Number of queues. The range of the value that equals to the number of cores involved in communication × the number of queues is [0, 40]. For details about how to set the number of cores involved in communication, see SetCommBlockNum.

Returns

0: Setting succeeded.
Other values: Setting failed.

Restrictions

This API takes effect only when the communication type is HCCL_CMD_BATCH_WRITE on the Atlas A3 training products/Atlas A3 inference products.

Example

const char *groupName = "testGroup";
uint32_t opType = HCCL_CMD_BATCH_WRITE;
std::string algConfig = "BatchWrite=level0:fullmesh";
uint32_t reduceType = HCCL_REDUCE_SUM;
AscendC::Mc2CcTilingConfig mc2CcTilingConfig(groupName, opType, algConfig, reduceType);
mc2CcTilingConfig.SetQueueNum(2U);
