dpgen run problem, how to using para_deg?

[llmxq]

i am now using bohrium platform. if i want to run two dp train jobs on one GPU, how do i set the parameters? i have tried to set para_deg = 2, but it didn't work. the following is the part of my machine.json file.
"resources": {
"number_node": 1,
"cpu_per_node": 8,
"gpu_per_node": 1,
"para_deg": 2,
"queue_name": "V100_8_32",
"group_size": 1,
"custom_flags": [],
"strategy": {"if_cuda_multi_devices": true},
"para_deg": 3,
"source_list": []

group_size should be no less than para_deg.
