If you only have one jobstep, a much cleaner solution is to use exec to start that step in the main BATCH process (solution courtesy Michael Boratko. If you cancel the job manually, make sure that you specify the signal as TERM like so scancel -signal=TERM. As a cluster workload manager, Slurm has three key functions. You want to run nine distinct copies of the Python script separately on each of those data files. Slurm requires no kernel modifications for its operation and is relatively self-contained. You have a Python script which reads one of those data files. trap 'echo signal recieved in BATCH! kill -15 "$ " The number of threads that can be used in parallel depends on the number of cores (parameter -cpus-per-task ) within the Slurm request, e.g. Slurm is an open source, fault-tolerant, and highly scalable cluster management and job scheduling system for large and small Linux clusters. # To avoid this, you can send SIGINT, # i.e., KeyboardInterrupt using (kill -2). # Note: Most python scripts don't install handler # for SIGTERM and hence might die a quick painful death # on recieveing SIGTERM (kill -15). # Send SIGTERM using kill to the internal script's # process and wait for it to close gracefully. We first ssh into the primary node (see part 2 of this series for details on SSH and. ![]() ![]() # Install trap for the signals INT and TERM to # the main BATCH script here. Ubuntu 22.04 comes with Python 3.8 preinstalled at the system level. #!/bin/bash #SBATCH -output=t.log #SBATCH # tells the controller # to send SIGTERM to the job 60 secs # before its time ends to give it a # chance for better cleanup.
