# cat lsf.csh
if ( "${path}" !~ *-slurm/etc* ) then
if ( -f /opt/hptc/lsf/top/conf/cshrc.lsf ) then
source /opt/hptc/lsf/top/conf/cshrc.lsf
endif
endif
The goal of these custom files is to source (only once) the appropriate LSF environment
file: $LSF_ENVDIR/cshrc.lsf for csh users, and $LSF_ENVDIR/profile.lsf for
users of sh, bash, and other shells based on sh.
Create /etc/profile.d/lsf.sh and /etc/profile.d/lsf.csh on the HP XC
system to set up the LSF environment on HP XC. Using /shared/lsf for the value of
LSF_TOP as an example, the new files would resemble these:
# cat lsf.sh
case $PATH in
*-slurm/etc:*) ;;
*:/shared/lsf/*) ;;
*)
if [ -f /shared/lsf/conf/profile.lsf.xc ]; then
. /shared/lsf/conf/profile.lsf.xc
fi
esac
# cat lsf.csh
if ( "${path}" !~ *-slurm/etc* ) then
if ( -f /shared/lsf/conf/cshrc.lsf.xc ) then
source /shared/lsf/conf/cshrc.lsf.xc
endif
endif
NOTE: The profile.lsf.xc and cshrc.lsf.xc scripts do not exist yet. We will
establish them after installing LSF with SLURM in a future step. Be sure to replace
/shared/lsf with the location of LSF_TOP on your system. Note that the names of
the setup files are appended with .xc.
After installing LSF with SLURM, rename the setup files to avoid disturbing the existing
setup files. These new custom files /etc/profile.d/lsf.sh and /etc/profile.d/
lsf.csh must be propagated to every node in the HP XC system; this is done in an
upcoming step.
