LSF uses the directory specified in the execution cluster and ignores the directory specified in the submission cluster.
LSF writes the checkpoint file in a subdirectory named with the submission cluster name and submission cluster job ID. This allows LSF to checkpoint multiple jobs to the same checkpoint directory. For example, the submission cluster is ClusterA, the submission job ID is 789, and the send-jobs queue enables checkpointing. The job is forwarded to clusterB, the execution job ID is 123, and the receive-jobs queue specifies a checkpoint directory called XYZ_dir. LSF will save the checkpoint file in:
In this example, users in a remote cluster submit work to a data center using a send-jobs queue that is configured to forward jobs to only one receive-jobs queue. You are the administrator of the data center and you need to shut down a host for maintenance. The host is busy running checkpointable MultiCluster jobs.
