About this task
By default, memory is reserved for parallel jobs on a
per-host basis. For example, by default, the command:
bsub -n 4 -R "rusage[mem=500]" -q reservation myjob
requires the job to reserve 500 MB on each host
where the job runs.
Procedure
To enable per-slot memory reservation, define RESOURCE_RESERVE_PER_SLOT=y
in lsb.params. In this example, if per-slot reservation
is enabled, the job must reserve 500 MB of memory for each job slot
(4 * 500 = 2 GB) on the host in order to run.
