Function Description

AscendIndexCluster needs to use Init to initialize corresponding resources. After the initialization is complete, a complete space is allocated to store the database. Then, Finalize is called to destroy the resources.

AscendIndexCluster supports only the vector inner product distance type in standard deployment mode of the Atlas inference product. AscendIndexCluster depends on the Flat and AICPU operators. For details, see Flat and AICPU.

Multi-thread concurrent calling is supported. You need to set the environment variable MX_INDEX_MULTITHREAD to 1, that is, export MX_INDEX_MULTITHREAD=1. If this variable is set to another value or is not set, the multi-thread function is disabled. Currently, FeatureRetrieval uses the OMP for performance acceleration. The OMP cannot be used together with other multi-thread mechanisms. If new threads are repeatedly created to use the OMP, the memory usage keeps increasing. Therefore, you are advised to use fixed threads to run retrieval tasks.
