scontrol show node orange01
scontrol show node orange02
show? Just to see if there's a default node weight hanging around, and if your weight changes have been picked up.

I'm experimenting with node weights and I'm very puzzled by what I see. Looking at the documentation I gathered that jobs will be allocated to the nodes with the lowest weight which satisfies their requirements. I have 3 nodes in a partition and I have defined the nodes like so..
NodeName=orange01 Procs=48 Sockets=8 CoresPerSocket=6 ThreadsPerCore=1 RealMemory=1018990 State=UNKNOWN Weight=50
NodeName=orange[02-03] Procs=48 Sockets=8 CoresPerSocket=6 ThreadsPerCore=1 RealMemory=1018990 State=UNKNOWN
So, given that the default weight is 1 I would expect jobs to be allocated to orange02 and orange03 first. I find, however that my test job is always allocated to orange01 with the higher weight. Have I overlooked something? I would appreciate your advice, please.
