Does integrating Airflow + Slurm for ML training pipelines make sense? We can have access to a cheap cluster which we want to use only for model training tasks between around 500 concurrent users (the deployment pipeline is different), and I was wondering if using SLURM for the scheduling and management of the training pipeline might make sense. Bases: airflow. {"payload":{"allShortcutsEnabled":false,"fileTree":{"":{"items":[{"name":". When a jobs file is submitted, the sbatch command is used for each job. There are two types of executor - those that run tasks locally (inside the scheduler process), and those that run their tasks remotely (usually via a pool of workers). In this presentation we will introduce the hardest challenge we had to overcome: adapting Airflow to run on multiple Slurm-managed HPC clusters by using deferrable operators. We include multiple examples of working pod operators below, but we would also like to explain a few necessary components if you want to See the License for the # specific language governing permissions and limitations # under the License. - sunset666/Airflow-Slurm-Executor If you want Nextflow to distribute your jobs using the SLURM cluster you’ll need to generate a SLURM executor config that Nextflow understands. penv. celery_executor; airflow.
