Specify y to enable LSF memory limit enforcement.
If enabled, LSF sends a signal to kill all processes that exceed queue-level memory limits set by MEMLIMIT in lsb.queues or job-level memory limits specified by bsub -M mem_limit.
Otherwise, LSF passes memory limit enforcement to the OS. UNIX operating systems that support RLIMIT_RSS for setrlimit() can apply the memory limit to each process.
