Ingmar,

While not using a Cray, I do run gold and moab on different servers (having to do with failover).  The Moab integration is very straightforward, e.g.:

AMCFG[bank]     SERVER=gold://Linuxbox/ TIMEOUT=15
AMCFG[bank]     CHARGEPOLICY=DEBITALLBLOCKED
AMCFG[bank]     NODECHARGEPOLICY=MAX
AMCFG[bank]     JOBFAILUREACTION=HOLD
AMCFG[bank]     FLUSHINTERVAL=12:00:00


Normally gold gets sent the number of cores and CPU time and calculates charges based on its "machine"-related attributes.  For finer control (I have different node generations) I use this:


# http://www.clusterresources.com/products/mwm/docs/6.4allocationmanagement.shtml#flags
# To use node-specific CHARGERATE as defined below, set LOCALCOST
AMCFG[bank]     FLAGS=LOCALCOST
...
NODECFG[n143]   RACK=5  SLOT=36 PROCSPEED=2667  SPEED=1.0 CHARGERATE=0.5
NODECFG[n144]   RACK=6  SLOT=36 PROCSPEED=2667  SPEED=1.0 CHARGERATE=0.5

NODECFG[n145]   RACK=9  SLOT=1  PROCSPEED=2533  SPEED=2.5 CHARGERATE=1.0
NODECFG[n146]   RACK=10 SLOT=1  PROCSPEED=2533  SPEED=2.5 CHARGERATE=1.0
...


With best regards,
