We set DefMemPerCPU in each partition to approximately the amount of RAM in a
node divided by the number of cores in the node. For heterogeneous partitions,
we use a lower limit, and we always reserve a bit of RAM for the OS, too. So
for a 64 GB node with 28 cores, we default to 2000 M per CPU,
Spencer,
Thank you for your response!
It does appear that the memory allocation was the issue. When I specify
--mem=1, I am able to queue jobs on a single node.
That being said, I was under the impression that the DefMemPerCPU,
DefMemPerNode (what sbatch claims to default to), etc. values defa
Jason,
The array jobs are designed to behave like independent jobs (but are stored
more efficiently internally to avoid straining the controller). So in principle
slurm could schedule them one per node or multiple per node. The --nodes and
--ntasks parameters apply to individual jobs in the arr
Hello all,
I have a couple of users, each of whom has contributed funds to purchase a
node for the cluster, much like a condo system. Each node has 52 cores, so
I'd like to provide each user with preempt access for up to 52 cores. I can
configure that easily enough with a QOS for each user with Gr
Hello,
I am new to Slurm and I am working on setting up a cluster. I am testing out
running a batch execution using an array and am seeing only one task executed
in the array per node. Even if I specify in the sbatch command that only one
node should be used, it executes a single task on each o

We use Active Directory, so I created a script that iterates all the
cluster-related AD groups and generates
Hello all.
We'd need to setup two QoS:
- debug : low priority, max 15' wall time, unaccounted CPU time
- hpc: should get "half node" allocation units for accounting purposes
(both for CPU and RAM)
For "debug" I tried (and obviously failed):
# sacctmgr create qos debug MaxJobsPerUser=1 MaxSubmitJo
