> How do I do if I want to submit alternatively to one of the three nodes: host5, host6 or host7 ? If I specifify this:  
> qsub -l nodes=host5,nodes=host6,nodes=host7  
> Will it submit to host5 or alternatively to host6 (or host7) when there is no more available resources on host5 (or host6) ?

[Answer]: No, you need to create qsub wrapper script based on the logic of selecting one of the nodes, which will take the inputs from user and submit the job alternatively.
