Hello,
Thank you for your answer, but it doesn't solve my problem. I want to
use a preemption based on QOS, not on the partition.
I want three levels of preemption, 'def', 'hi' and 'veryhi', for each
project (I have 10 projets).
partition 'hi' can preempt partition 'def'.
But I want the 'veryhi' partitions only be able to preempt the 'hi'
jobs of their project or 'def' jobs.

I am not sure I fully understand your question, but if I do I believe
the problem is that you forgot to add
PreemptMode=off
to the partitions which you do NOT want to be preempted, otherwise
everything gets the cluster default. For example I have configured
mine as follows
PreemptType = preempt/partition_prio
PreemptMode=REQUEUE
PartitionName=highpriority DefMemPerCPU=4580 Nodes=node[01-36]
PreemptMode=off PriorityTier=500 State=UP
PartitionName=lowpriority DefMemPerCPU=4580 Nodes=node[01-36]
PreemptMode=cancel PriorityTier=100 State=UP
and only jobs in the lowpriority partition get cancelled, other
partitions (not shown) get requeued and highpriority one are left alone

Hello,
I want too use QOS preemption.
my configuration is :
preemptMode = GANG,SUSPEND
PreemptParameters = (null)
PreemptType = preempt/qos
PriorityType = priority/multifactor
SelectType = select/cons_tres
SelectTypeParameters = CR_CPU
I define 3 partitions :
PartitionName=DEFAULT Nodes=ALL Default=NO MaxTime=15-0 State=UP
OverSubscribe=FORCE:1 PreemptMode=suspend
PartitionName=veryhi PriorityTier=30
AllowQos=veryhi_short,gaia_veryhi_short
PartitionName=hi PriorityTier=20 AllowQos=hi_short,gaia_hi_short
PartitionName=def PriorityTier=10 OverSubscribe=No
Default=YES
AllowQos=def_short
I define 5 QOS :
sacctmgr show qos format=name%20,Priority,Preempt%40,PreemptMode
Name Priority Preempt PreemptMode
----------------------- ------------
----------------------------------
---------------
normal 0 cluster
veryhi_short 20000 def_short suspend
hi_short 10000 def_short suspend
def_short 0 normal suspend
gaia_veryhi_short 20000 def_short,gaia_hi_short suspend
gaia_hi_short 10000 def_short suspend
I define account :
sacctmgr show ass format=account%20,user,qos%60
Account
User QOS
-------------------- --------
--------------------------------------------
gaia_hi user1 gaia_hi_short
gaia_veryhi user1 gaia_veryhi_short
mis_hi user1 hi_short
def user1
def_short
I submit 2 jobs :
JOBID PARTITION QOS ACCOUNT NAME USER
STATE PRIORITY
159 hi hi_short mis_hi test user1
SUSPENDE 637
160 veryhi gaia_veryhi_short gaia_veryhi test user1
RUNNING 1150
I don't understand why job 160 suspend job 159, the partition
priority
is higher, but I want gaia_veryhi_short QOS preempt only
def_short and
gaia_hi_short QOS.
The QOS of job 159 is hi_short.
Where is my configuration error ?
Thanks for your time,
Aurélia
