"""
max_data_len : maximum data length, sum of maximum sequence lengths on all NPU cores. Defaults to 4096.
max_seq_len : maximum sequence length. Defaults to 4096.
max_cache_len : maximum cache length. Defaults to 4096.
random_seq_len_calib : sequence length for random calibration. Defaults to 80.
use_full_seq_len_calib : whether to use full sequence length for calibration for the last attention layer. Defaults to False.
use_custom_mask_input : whether to use custom mask input. Defaults to False.
start_dram_offset : start dram offset. Defaults to 0.
use_global_core : whether to use global core. Defaults to False.
llm_batch_size : batch size for LLM. Defaults to 1.
npu_core_ids : NPU core IDs to use(batched LLM). Defaults to [0]. If the llm_batch_size is greater than 1, then defaults to [0, 1, 2, 3, 4, 5, 6, 7].
