Task Files
There are 3 task list files that can affect a job:
◆ lsf.task—system-wide defaults apply to all LSF users, even across multiple
clusters if MultiCluster is installed
◆ lsf.task.cluster_name —cluster-wide defaults apply to all users in the
cluster
◆ $HOME/.lsftask—user-level defaults apply to a single user
This file lists applications to be added to or removed from the default system lists
for your jobs. Resource requirements specified in this file override those in the
system lists.
The clusterwide task file is used to augment the systemwide file. The user’s task file is
used to augment the systemwide and clusterwide task files.
LSF combines the systemwide, clusterwide, and user-specific task lists for each user's
view of the task list. In cases of conflicts, such as different resource requirements
specified for the same task in different lists, the clusterwide list overrides the systemwide
list, and the user-specific list overrides both.
LSF_CONFDIR/lsf.task
Systemwide task list applies to all clusters and all users.
This file is used in a MultiCluster environment.
LSF_CONFDIR/lsf.task.cluster_name
Clusterwide task list applies to all users in the same cluster.
$HOME/.lsftask
User task list, one per user, applies only to the specific user. This file is automatically
created in the user’s home directory whenever a user first updates his task lists using the
lsrtasks or lsltasks commands. For details about task eligibility lists, see the man
page
ls_task(3).
Permissions
Only the LSF administrator can modify the systemwide task list(lsf.task) and the
clusterwide task list(
lsf.task.cluster_name).
A user can modify his own task list(
.lsftask) with the lsrtasks and lsltasks
commands. See the man pages
lsrtasks(1) and lsltasks(1) for more details.
