Thank you Brain,
Another question is can one node has different weight for different partition?
E.G node1 0.8 in Partition high but 0.5 in partition low?
Best regards,
Bill

Yes, if you put a weight parameter to the nodes.
From the manpage:
Weight
The priority of the node for scheduling purposes. All things
being equal, jobs will be allocated the nodes with the lowest weight
which satisfies their requirements. For example, a heterogeneous
collection of nodes might be placed into a single partition for greater
system utilization, responsiveness and capability. It would be
preferable to allocate smaller memory nodes rather than larger memory
nodes if either will satisfy a job's requirements. The units of weight
are arbitrary, but larger weights should be assigned to nodes with more
processors, memory, disk space, higher processor speed, etc. Note that
if a job allocation request can not be satisfied using the nodes with
the lowest weight, the set of nodes with the next lowest weight
is added to the set of nodes under consideration for use (repeat as
needed for higher weight values). If you absolutely want to minimize
the number of higher weight nodes allocated to a job (at a cost of
higher scheduling overhead), give each node a distinct Weight value
and they will be added to the pool of nodes being considered for
scheduling individually. The default value is 1.

Hi Everyone,
For example, I have two partitions, high,low each has same nodes
node[1-10], When we submit job to high partition the nodes order is
node1,node2......node10, when we submit job to low partition, the
order is node10,node9......node1.
Is it possible to do that?
Thanks in advance,
Bill
