About Resource Requirements
About Resource Requirements
Resource requirements define which hosts a job can run on. Each job has its
resource requirements. Hosts that match the resource requirements are the
candidate hosts. When LSF schedules a job, it uses the load index values of all
the candidate hosts. The load values for each host are compared to the
scheduling conditions. Jobs are only dispatched to a host if all load values are
within the scheduling thresholds.
By default, if a job has no resource requirements, LSF places it on a host of the
same type as the submission host (i.e., type==any). However, if a job has
string or Boolean resource requirements specified and the host type has not
been specified, LSF places the job on any host (i.e., type==any) that satisfies
the resource requirements.
To override the LSF defaults, specify resource requirements explicitly. Resource
requirements can be set for queues, for individual applications, or for
individual jobs.
To best place a job with optimized performance, resource requirements can be
specified for each application. This way, you do not have to specify resource
requirements every time you submit a job. The LSF administrator may have
already configured the resource requirements for your jobs, or you can put
your executable name together with its resource requirements into your
personal remote task list.
The bsub command automatically uses the resource requirements of the job
from the remote task lists.
A resource requirement is an expression that contains resource names and
operators.
