This topic should definitely be put in a FAQ... as it is asked 3 or 4 
times a year.

Here is the method I use there :

- colorize the nodes, ie in the server_priv/nodes file of Torque, put 
attributes like that :

callas01 np=2 opteron
callas02 np=2 opteron
abeille01 np=2 xeon
abeille02 np=2 xeon

- then use the color in the queues :


set queue intel resources_default.nodes = 1:xeon
set queue intel resources_default.neednodes = xeon

set queue amd resources_default.neednodes = callas
set queue amd resources_default.nodes = 1:callas

- finally for MAUI to take it in account, put the 2 lines in maui.cfg :

CLASSCFG[opteron]
CLASSCFG[xeon]


Then when you submit jobs use the queues "intel" for xeon nodes and 
"amd" for opteron nodes.

Please note that if you force the start of a job waiting for a color to 
be free, it can start on the other color nodes...
