[Mauiusers] NodeAllocationPolicy and Partitions

Dear all,
(1) We are using maui-3.2.6p13 and we have a problem with the
configuration of NODEALLOCATIONPOLICY=FASTEST in combination with
configured PARTITION values of each node.
What I mean is: in maui.cfg there is such a line for each node:
NODECFG[cn1] SPEED=1.0 PARTITION=SLOW
...
NODECFG[cn50] SPEED=2.0 PARTITION=FAST
If no partition is requested the scheduler always uses nodes with lowest
SPEED. If PARTITION:FAST is requested the scheduler uses the nodes with
lowest SPEED in this partition.
Before we configured partitions in our cluster the scheduler always took
nodes with the highest speed value.
So, what is to do to realize FASTEST correctly?
(2) Another problem with patitions arises when we configure standig
reservations. Without
SRCFG[wartung] PARTITION=ALL
the reservation is only for the first partition, even though all nodes
are listed in HOSTLIST.
Thanks!
Henrik
