LSF Version 7.3 - Platform LSF Configuration Reference

Configuration to specify the directory for application-level
executables
By default, LSF looks for application-level checkpoint and restart executables in
LSF_SERVERDIR. You can modify this behavior by specifying a different directory as an
environment variable or in lsf.conf.
Configuration
file
Parameter and syntax Behavior
lsf.conf
LSB_ECHKPNT_METHOD_DIR=
path
•
Specifies the absolute path to the directory that contains
the echkpnt.application and erestart.application
executables
•
User accounts that run these executables must have the
correct permissions for the
LSB_ECHKPNT_METHOD_DIR directory.
Configuration to save standard output and standard error
By default, LSF redirects the standard output and standard error from checkpoint and restart
executables to /dev/null and discards the data. You can modify this behavior by defining
the parameter LSB_ECHKPNT_KEEP_OUTPUT as an environment variable or in
lsf.conf.
