Specifying resource requirements

About resource requirements
Resource requirements define which hosts a job can run on. Each job has its resource requirements and 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.
Queue-level resource requirements
Each queue can define resource requirements that apply to all the jobs in the queue.
Job-level resource requirements
Each job can specify resource requirements. Job-level resource requirements override any resource requirements specified in the remote task list.
Resource requirement strings
Most LSF commands accept a -R res_req argument to specify resource requirements. A resource requirement string describes the resources that a job needs. The exact behavior depends on the command. LSF uses resource requirements to select hosts for remote execution and job execution. Resource requirement strings can be simple (applying to the entire job) or compound (applying to the specified number of slots).
Specify GPU resource requirements for your jobs
Specify all GPU resource requirements as part of job submission, or in a queue or application profile, or use the default GPU requirement "num=1:mode=shared:mps=no:j_exclusive=no". Use the option bsub –gpu to submit jobs that require GPU resources. Specify how LSF manages GPU mode (exclusive or shared), and whether to enable the NVIDIA Multi-Process Service (MPS) for the GPUs used by the job.
