Node to queue mapping is not recommended and is not efficient in terms of resource usage by the end users. It is recommended to configure Qlists instead.
- qlists ( refer : 4.9.2.2.i Procedure to Associate Vnodes with Multiple
queues https://www.pbsworks.com/pdfs/PBS18.2_BigBook.pdf )
You can use reservations ( Advance or Standing) here with Qlist configuration without any issues.
