Are there any default resource limits set for jobs?

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

+MaxRuntime = 1200
request_memory = 2G
request_CPUs = 1 

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.
