LSF Version 7.3 - Platform LSF Configuration Reference

Scope
Applicability Details
Operating system
•
UNIX and Linux
•
Windows
Security
•
Data passing between esub on the submission host and eexec on the execution host
is not encrypted.
Job types
•
Batch jobs submitted with bsub or modified by bmod.
•
Batch jobs restarted with brestart.
•
Interactive tasks submitted with lsrun and lsgrun (eexec only).
Dependencies
•
UNIX and Windows user accounts must be valid on all hosts in the cluster, or the
correct type of account mapping must be enabled.
•
For a mixed UNIX/Windows cluster, UNIX/Windows user account mapping must
be enabled.
•
For a cluster with a non-uniform user name space, between-host account mapping
must be enabled.
•
For a MultiCluster environment with a non-uniform user name space, cross-cluster
user account mapping must be enabled.
•
User accounts must have the correct permissions to successfully run jobs.
•
An eexec that requires root privileges to run on UNIX or Linux, must be configured to
run as the root user.
Limitations
•
Only an esub invoked by bsub can change the job environment on the submission
host. An esub invoked by bmod or brestart cannot change the environment.
•
Any esub messages provided to the user must be directed to standard error, not to
standard output. Standard output from any esub is automatically passed to eexec.
•
An eexec can handle only one standard output stream from an esub as standard
input to eexec. You must make sure that your eexec handles standard output from
correctly if any esub writes to standard output.
•
The esub/eexec combination cannot handle daemon authentication. To configure
daemon authentication, you must enable external authentication, which uses the
eauth executable.
Configuration to enable job submission and execution controls
This feature is enabled by the presence of at least one esub or one eexec executable in the
directory specified by the parameter LSF_SERVERDIR in lsf.conf. LSF does not include a
default esub or eexec; you should write your own executables to meet the job requirements
of your site.
Feature: External job submission and execution controls
