Are there any default resource limits set for jobs?

A: Default values are set for walltime, CPUs, memory and scratch. You can adjust these values at a job_submission_file.

+MaxRuntime = 1200
request_cpus = 1
request_memory = 2G ... per one core
request_disk = 20G ... per one core

The value of maximum walltime is set to two weeks.

Jobs that exceed MaxRuntime or a triple value of request_memory will be killed by the batch system.
Jobs that exceed a required value for scratch will be set to HOLD state.
