guppy_basecall_server --log_path <log_dir_location> --config dna_r9.4.1_450bps_fast_prom.cfg --num_callers 12 --ipc_threads 20 --device "cuda:0 cuda:1 cuda:2 cuda:3" --port ipc:///tmp/.guppy/5556 --num_alignment_threads 24 --max_queued_reads 20000

--log_path
or-l
argument. Log files can be used for debugging.The server needs to be launched in a location where it can continue to run until it is shut down. For example, start a separate terminal session to manage the server, or launch the server in the background before starting basecalling.
