lsplace
displays hosts available to execute tasks
SYNOPSIS
lsplace [-L] [-n minimum | -n 0] [-R res_req] [-w maximum | -w 0]
[host_name ...]
lsplace [-h | -V]
DESCRIPTION
Displays hosts available for the execution of tasks, and temporarily increases the load on
these hosts (to avoid sending too many jobs to the same host in quick succession). The
inflated load will decay slowly over time before the real load produced by the dispatched
task is reflected in the LIM’s load information. Host names may be duplicated for
multiprocessor hosts, to indicate that multiple tasks can be placed on a single host.
By default, displays only one host name.
By default, uses LSF default resource requirements.
OPTIONS
-L
Attempts to place tasks on as few hosts as possible. This is useful for distributed parallel
applications in order to minimize communication costs between tasks.
-n minimum | -n 0
Displays at least the specified number of hosts. Specify 0 to display as many hosts as
possible.
Prints
Not enough host(s) currently eligible and exits with status 1 if the
required number of hosts holding the required resources cannot be found.
-R res_req
Displays only hosts with the specified resource requirements.
-w maximum | -w 0
Displays no more than the specified number of hosts. Specify 0 to display as many hosts
as possible.
host_name ...
Displays only hosts that are among the specified hosts.
-h
Prints command usage to stderr and exits.
-V
Prints LSF release version to stderr and exits.
