LSF Version 7.3 - Platform LSF Configuration Reference

Applicability Details
Dependencies
•
UNIX and Windows user accounts must be valid on all hosts in the cluster and must
have the correct permissions to successfully run jobs.
•
For clusters that include both UNIX and Windows hosts, you must also enable the
UNIX/Windows user account mapping feature.
Limitations
•
For a MultiCluster environment that has different user accounts assigned to
different hosts, you must also enable the cross-cluster user account mapping
feature. Do not configure between-host user account mapping if you want to use
system-level mapping in a MultiCluster environment; LSF ignores system-level
mapping if mapping local user mapping is also defined in .lsfhosts.
•
For Windows workgroup account mapping in a Windows workgroup environment,
all jobs run using the permissions associated with the specified system account.
Configuration to enable between-host user account mapping
Between-host user account mapping can be configured in one of the following ways:
•
Users can map their local accounts at the user level in the file .lsfhosts. This file must
reside in the user’s home directory with owner read-write permissions for UNIX and owner
read-write-execute permissions for Windows. Save the .lsfhosts file without a file
extension. Both the remote and local hosts must have corresponding mappings in their
respective .lsfhosts files.
•
LSF administrators can set up Windows workgroup account mapping at the system level
in lsb.params.
Local user account mapping configuration
Local user account mapping is enabled by adding lines to the file .lsfhosts. Both the remote
and local hosts must have corresponding mappings in their respective .lsfhosts files.
