[slurm-users] Increasing job priority based on resources requested.

[Prentice Bisbal]

Slurm-users,

Is there away to increase a jobs priority based on the resources or 
constraints it has requested?

For example, we have a very heterogeneous cluster here: Some nodes only 
have 1 Gb Ethernet, some have 10 Gb Ethernet, and others have DDR IB. In 
addition, we have some large memory nodes with RAM amounts ranging from 
128 GB up to 512 GB. To allow a user to request IB, I have implemented 
that as a feature in the node definition so users can request that as a 
constraint.

I would like to make it that if a job request IB, it's priority will go 
up, or if it requests a lot of memory (specifically memory-per-cpu), 
it's priority will go up proportionately to the amount of memory 
requested. Is this possible? If so, how?

I have tried going through the documentation, and googling, but 
'priority' is used to discuss job priority so much, I couldn't find any 
search results relevant to this.
