LSF_DYNAMIC_HOST_TIMEOUT specifies the length of time (minimum 10 minutes) a dynamic host is unavailable before the master host removes it from the cluster. Each time LSF removes a dynamic host,
mbatchd automatically reconfigures itself.
Note: For very large clusters, defining this parameter could decrease system performance. If you want to use this parameter to remove dynamic hosts from a very large cluster, disable the parameter after LSF has removed the unwanted hosts.
