Westmere and Sandy Bridge in the Same Queue using Complex Attributes
What we want:
- our 12-core Westmere exec hosts and our 12-core Sandy-Bridge exec hosts in the same queue, with an optional switch to select a SB node;
- jobs which do not select the SB switch to run on Westmere and SB nodes;
- jobs which do select the SB switch to run on only SB nodes (therefore may have to wait longer).
