HP XC System Software Installation Guide Version 3.2

I LSF and SLURM Environment Variables
This appendix lists the default values for LSF and SLURM environment variables that were set
during the HP XC System Software installation process.
For more information about setting LSF environment variables and parameters listed in Table I-1,
see the Platform LSF Reference manual.
Table I-1 Default Installation Values for LSF and SLURM
Where is this Value
Stored?DescriptionDefault ValueEnvironment Variable
lsb.params file
This value is set to 0 when
LSF-HPC with SLURM is
installed, and is set with
the default (1) when
standard LSF is installed.
This environment variable
controls how many jobs
are dispatched to a host
during a scheduling cycle.
Because the HP XC system
is considered one host
when LSF-HPC with
SLURM is installed, this
value is set to 0 to allow
the scheduler to dispatch
as many jobs as possible
on HP XC during each
scheduling cycle.
1JOB_ACCEPT_INTERVAL
lsb.params file
Controls the maximum
number of files mbatchd
can have open and
connected to sbatchd.
32MAX_SBD_CONNS
lsf.conf file
Specifies the mail program
to use.
sendmailLSB_MAILPROG
lsf.conf file
Enables external
scheduling.
YLSF_ENABLE_EXTSCHEDULER
lsf.conf file
Sets the TCP port for
communication between
the LSF HPC allocation
adapter (RLA), sbatchd
and the SLURM scheduler
plug-in.
6883LSB_RLA_PORT
lsf.conf file
This environment variable
is needed so that LSF
commands that are
launched from the rest of
the HP XC nodes know to
which nodes to send their
requests. This environment
variable is not needed for
standard LSF.
lsfhost.localdomainLSF_SERVER_HOSTS
lsf.conf file
Displays an abbreviated
list of hosts in bjobs and
bhist for a parallel job
when multiple processes
of a job are running on a
host.
