Platform LSF Command Reference 259
lslogin
remotely logs in to a lightly loaded host
Synopsis
lslogin [-v] [-m "host_name ..." | -m "cluster_name ..."]
[-R "res_req"] [rlogin_options]
lslogin [-h | -V]
Description
Remotely logs in to a lightly loaded host.
By default,
lslogin selects the least loaded host, with few users logged in, and
remotely logs in to that host using the UNIX
rlogin command.
In a MultiCluster environment, the default is to select the least loaded host in the
local cluster.
Options
-v Displays the name of the host to which lslogin remotely logs you in.
-m "host_name ..." | -m "cluster_name ..."
Remotely logs in to the specified host.
With MultiCluster job forwarding, when a cluster name is specified, remotely logs
in to the least loaded host in the specified cluster, if the remote cluster accepts
interactive jobs from the local cluster (see
lsf.cluster(5)).
-R "res_req" Remotely logs in to a host that meets the specified resource requirement. The
resource requirement expression restricts the set of candidate hosts and determines
the host selection policy.
For a complete explanation of resource requirement expressions, see Administering
Platform LSF. To find out what resources are configured in your system, use
lsinfo
and
lshosts.
rlogin_options Specify remote login options passed to the rlogin command.
If remote execution fails,
lslogin logs in locally only if the local host also satisfies
required resources; otherwise, log in fails.
-h Prints command usage to stderr and exits.
-V Prints LSF release version to stderr and exits.
Example
lslogin -R "select[it>1 && bsd]"
Remotely logs in to a host that has been idle for at least 1 minute, that runs BSD
UNIX, and is lightly loaded both in CPU resources and the number of users logged
in.
