Easily deploy Dask on job queuing systems like PBS, Slurm, MOAB, SGE, LSF, and HTCondor.
The Dask-jobqueue project makes it easy to deploy Dask on common job queuing systems typically found in high performance supercomputers, academic research institutions, and other clusters. It provides a convenient interface that is accessible from interactive systems like Jupyter notebooks, or batch jobs.
from dask_jobqueue import PBSCluster cluster = PBSCluster() cluster.scale(jobs=10) # Deploy ten single-node jobs from dask.distributed import Client client = Client(cluster) # Connect this local process to remote workers # wait for jobs to arrive, depending on the queue, this may take some time import dask.array as da x = ... # Dask commands now use these distributed resources
Dask jobqueue can also adapt the cluster size dynamically based on current load. This helps to scale up the cluster when necessary but scale it down and save resources when not actively computing.
cluster.adapt(minimum_jobs=10, maximum_jobs=100) # auto-scale between 10 and 100 jobs cluster.adapt(maximum_memory="10 TB") # or use core/memory limits
