Hello,
I'm using slurm version 19.05.2 on debian 10.
I'm try to hand a SIGINT signal by a child process of a batch.
The signal is automatically send 30 s before the end of time.
You can see this mechanism in this minimal example:

That's right. Thank to Bjørn-Helge who help me.
You must enable swapaccount in the kernel as shown here:

It was the case, I make a mistake when I copy/cut... So, I haven't space here.

Hello,
I tried using, in slurm.conf
TaskPlugin=task/affinity, task/cgroup
SelectTypeParameters=CR_CPU_Memory
MemLimitEnforce=yes
and in cgroup.conf:
CgroupAutomount=yes
ConstrainCores=yes
ConstrainRAMSpace=yes
ConstrainSwapSpace=yes
MaxSwapPercent=10
TaskAffinity=no
But when the job
Hello,
Is there a way to preempt jobs by using the priority of a job calculate with
priority_multifactor and not with a priority related to partition or qos ?
I tried using PreemptType=preempt/partition_prio in slurm.conf but it doesn't
work and I haven't seen this type of use case in the doc

Hello,
Most jobs of my users are single-thread. I have multithreaded processors. The
jobs seem to reserve 2 logical CPU (1 core=2 CPU (2 threads)) whereas it only

Hello,
Do you know a command to get a summary of the use of compute nodes and/or
partition of a cluster in real time ? Something with a output like this:
$ sutilization
Partition/Node_Name CPU_Use CPU_Total %Use
standard 236 564 41,8 %
n001 36 72 50 %
n002 18 72 25 %

the same time (--array=1-100%10), all jobs succeed. But if I force slurm to
execute only 30 jobs at the same time (--array=1-100%30), I have a part that
fails again.
Has anyone ever faced this type of problem? If so, please kindly enlighten me.
