My problem is that i have for instance 100 CPU, and i want to create two partition each with 50 CPU maximum usage. In this way i can submit job to both partitions independently.<br>

I wonder what you really want to achieve? Why do you want to divide your 100 CPUs (nodes or CPU cores?) into 2 partitions? The queue will be much more flexible if identical nodes constitute 1 partition.<br>
<br>
If you really insist on splitting up your nodes into 2 partitions, you can configure that in slurm.conf, for example with 100 nodes named a001..a100:<br>
<br>
PartitionName=partition1 Nodes=a[001-050]<br>
PartitionName=partition2 Nodes=a[051-100]<br>
<br>
If you wish, you can look at my Slurm Wiki pages for inspiration:<br>

Hi,<br>
<br>
how can i limit the number of CPU that a partition can use?<br>
<br>
For instance when a partition reach its maximum CPUs number you can<br>
submit new job but they are put in queue.<br>
