bhpart
displays information about host partitions
SYNOPSIS
bhpart [-r] [host_partition_name ...]
bhpart [-h | -V]
DESCRIPTION
By default, displays information about all host partitions. Host partitions are used to configure host-partition fairshare scheduling.
OPTIONS
-r
Displays the entire information tree associated with the host partition recursively.
host_partition_name ...
Displays information about the specified host partitions only.
-h
Prints command usage to stderr and exits.
-V
Prints LSF release version to stderr and exits.
OUTPUT
The following fields are displayed for each host partition:
HOST_PARTITION_NAME
Name of the host partition.
HOSTS
Hosts or host groups that are members of the host partition. The name of
a host group is appended by a slash (/) (see bmgroup(1)).
USER/GROUP
Name of users or user groups who have access to the host partition (see
bugroup(1)).
SHARES
Number of shares of resources assigned to each user or user group in this
host partition, as configured in the file lsb.hosts. The shares affect
dynamic user priority for when fairshare scheduling is configured at the
host level.
PRIORITY
Dynamic user priority for the user or user group. Larger values represent higher priorities. Jobs belonging to the user or user group with the highest priority are considered first for dispatch.
In general, users or user groups with larger SHARES, fewer STARTED and RESERVED, and a lower CPU_TIME and RUN_TIME will have higher PRIORITY.
STARTED
Number of job slots used by running or suspended jobs owned by users or user groups in the host partition.
RESERVED
Number of job slots reserved by the jobs owned by users or user groups in the host partition.
CPU_TIME
Cumulative CPU time used by jobs of users or user groups executed in the host partition. Measured in seconds, to one decimal place.
LSF calculates the cumulative CPU time using the actual (not normalized)
CPU time and a decay factor such that 1 hour of recently-used CPU time
decays to 0.1 hours after an interval of time specified by HIST_HOURS in
lsb.params (5 hours by default).
RUN_TIME
Wall-clock run time plus historical run time of jobs of users or user groups that are executed in the host partition. Measured in seconds.
LSF calculates the historical run time using the actual run time of finished
jobs and a decay factor such that 1 hour of recently-used run time decays
to 0.1 hours after an interval of time specified by HIST_HOURS in
lsb.params (5 hours by default). Wall-clock run time is the run time of
running jobs.
FILES
Reads lsb.hosts.
