[slurm-users] preempt/qos is not working as expected

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
