LSF Version 7.3 - Platform LSF Configuration Reference

Description
Displays an abbreviated list of hosts in bjobs and bhist for a parallel job where multiple
processes of a job are running on a host. Multiple processes are displayed in the following
format:
processes*hostA
For example, if a parallel job is running 5 processes on hostA, the information is displayed in
the following manner:
5*hostA
Setting this parameter may improve mbatchd restart performance and accelerate event replay.
Default
Not defined
LSB_SIGSTOP
Syntax
LSB_SIGSTOP=signal_name | signal_value
Description
Specifies the signal sent by the SUSPEND action in LSF. You can specify a signal name or a
number.
If LSB_SIGSTOP is set to anything other than SIGSTOP, the SIGTSTP signal that is normally
sent by the SUSPEND action is not sent.
If this parameter is not defined, by default the SUSPEND action in LSF sends the following
signals to a job:
•
Parallel or interactive jobs: 1. SIGTSTP is sent first to allow user programs to catch the
signal and clean up. 2. SIGSTOP is sent 10 seconds after SIGTSTP. SIGSTOP cannot be
caught by user programs.
•
Other jobs: SIGSTOP is sent. SIGSTOP cannot be caught by user programs. The same set
of signals is not supported on all UNIX systems. To display a list of the symbolic names of
the signals (without the SIG prefix) supported on your system, use the kill -l command.
Example
LSB_SIGSTOP=SIGKILL
In this example, the SUSPEND action sends the three default signals sent by the TERMINATE
action (SIGINT, SIGTERM, and SIGKILL) 10 seconds apart.
Default
Not defined. Default SUSPEND action in LSF is sent.
LSB_STDOUT_DIRECT
Syntax
LSB_STDOUT_DIRECT=y | Y
