WebbBatch System Slurm¶ ZIH uses the batch system Slurm for resource management and job scheduling. Compute nodes are not accessed directly, but addressed through Slurm. You specify the needed resources (cores, memory, GPU, time, ...) and Slurm will schedule your job for execution. When logging in to ZIH systems, you are placed on a login node. Webb19 feb. 2024 · Writing Slurm scripts for Job submission. Slurm submission scripts have two parts: (1) Resource Requests (2) Job Execution. The first part of the scripts specifies the number of nodes, maximum CPU time, the maximum amount of RAM, whether GPUs are needed, etc. that the job will request for running the computation task.

WebbIntroduction. To request one or more GPUs for a Slurm job, use this form: --gpus-per-node= [type:]number. The square-bracket notation means that you must specify the number of GPUs, and you may optionally specify the GPU type. Choose a type from the "Available hardware" table below.

Jobs that run on the same node might compete for memory resources and cause the other job to fail. When memory-based scheduling is disabled, we recommend that users don't specify the --mem-per-cpu or --mem-per-gpu options.

WebbNodes can have features assigned to them by the Slurm administrator. Users can specify which of these features are required by their job using the constraint option. If you are looking for 'soft' constraints please see --prefer for more information. Only nodes having features matching the job constraints will be used to satisfy the request. WebbThere are other ways to specify memory such as --mem-per-cpu. Make sure you only use one so they do not conflict. Example Multi-Thread Job Wrapper Note: Job must support multithreading through libraries such as OpenMP/OpenMPI and you must have those loaded via the appropriate module. #!/bin/bash #SBATCH -J parallel_job # Job name
