Failed to setup in bigstation mode, and question about bigstation_mode performance

Hello, I try to test Agora in bigstation mode but failed, and I can't fix it. :(
I used sim_ul.json with a little modification:
{
"bs_radio_num": 8,
"ue_radio_num": 8,
"frame_schedule": [
"PUUUUUUUUUUUUU"
],
"modulation": "64QAM",
"Zc": 104,
"bs_server_addr": "127.0.0.1",
"bs_rru_addr": "127.0.0.1",
"fft_size": 2048,
"ofdm_data_num": 1200,
"demul_block_size": 64,
"freq_orthogonal_pilot": true,
/* Compute configuration */
"core_offset": 4,
"exclude_cores": [
0
],
"bigstation_mode": true,
"fft_thread_num": 8,
"demul_thread_num": 4,
"decode_thread_num": 4,
"worker_thread_num": 16,
"socket_thread_num": 1
}
And I got the below result (I attached it at the last)
(It works fine without bigstation mode.)
Could you please help find the reason? Thank you very much!
Also, I am curious about Agora's performance w/o bigstation mode. In fact, I am confused about how bigstation mode can improve PHY performance, since we just bind the different tasks to different CPUs without any other optimization, maybe we can benefit from cache? But it seems not such a big deal. Is there any theory or experiment result that can tell us that it is really useful?
Thank you very much!

There seems to be a bug with big station mode in Agora. Big station mode was designed for comparison vs Agora "normal" mode. Feel free to reference the result ( https://www.yecl.org/publications/ding2020conext.pdf ) but BigStation mode is only preferable in highly distributed systems where the Agora data-parallel design has increased cost of synchronization.
