選択肢

1. One job spreads over many nodes while another job leans on cards inside one node, so the spread job leans on the tight coupling and the packed job wants the paired coprocessor in that qualification.
2. One job spreads over many nodes while another job leans on cards inside one node, so the spread job leans on the tight coupling and the packed job wants the paired partitioning in that qualification.
3. One job spreads over many nodes while another job leans on cards inside one node, so the spread job leans on the tight compression and the packed job wants the paired partitioning in that qualification.
