Are the partitions dynamic? i.e. is the desire to limit based on partitions that float across a larger number of nodes and so the desire is to limit a particular partition to maximum amount of those nodes?

How can I limit the maximum number of CPUs that a partition can use. Thank You. 2018-01-02 18:28 GMT+01:00 Nicolò Parmiggiani <nicolo.parmiggi...@gmail.com<mailto:nicolo.parmiggi...@gmail.com>>: I have only one server and two data analysis pipelines, one for standard jobs and other one for high priority job that can be triggered sometimes. My first solution was to split the CPU of the server in two partition, one for each pipeline. A more complex (but i suppose better) solution could be to use one partition and manage the priority of the two pipeline and when i get jobs from high priority pipeline those jobs must start immediately, temporarily blocking standard jobs. What solution do you recommend? And how can I implement it?

In this way i can submit job to both partitions independently. 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. 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: PartitionName=partition1 Nodes=a[001-050] PartitionName=partition2 Nodes=a[051-100] If you wish, you can look at my Slurm Wiki pages for inspiration: https://wiki.fysik.dtu.dk/niflheim/SLURM https://wiki.fysik.dtu.dk/niflheim/Slurm_configuration 2018-01-02 11:29 GMT+01:00 Nicolò Parmiggiani <nicolo.parmiggi...@gmail.com<mailto:nicolo.parmiggi...@gmail.com> <mailto:nicolo.parmiggi...@gmail.com<mailto:nicolo.parmiggi...@gmail.com>>>: Hi, how can i limit the number of CPU that a partition can use? For instance when a partition reach its maximum CPUs number you can submit new job but they are put in queue. /Ole -- You received this message because you are subscribed to a topic in the Google Groups "slurm-users" group.
