I have not personally installed PBS Professional with ACE, but I had helped Joon Chae and team to install on a test/development system back in 2015.
I will share the notes that I took, specific to the PBS MOM installation. I don't know how you/Cray Japan will be setting up ACE, so these notes may not be applicable to you.
• Prerequisites for PBS Professional
o Setup of the PBS_HOME will be completed over NFS (/ha_cluster/pbs_shared/$hostname), which will be a symbolic link from the compute nodes /var/spool/PBS --> /ha_cluster/pbs_shared/$hostname. NOTE: ACE is setting up the appropriate exports, permissions, and symbolic links.
• Installation of PBS MOM on prod-000[1-3]
o CS team checked out the image, installed PBS Professional (using PBS default answers for the INSTALL script).
o Although, we did not start pbs_mom because we needed to "chkconfig pbs off". ACE will call a script to start pbs after it has verified the environment.
o Modified /etc/pbs.conf to include PBS_SCP=/usr/bin/scp
o Time was spent with Cray CS Team tweaking the ACE startup scripts
The /etc/pbs.conf and PBS_HOME/mom_priv/config files on nb-0001 are working for the temporary system. The critical point about PBS_HOME is that it is writable by the pbs_mom daemon on the compute node. In other words, please do NOT install PBS_HOME on a read-only mount.
The /etc/pbs.conf file has some variables commented out in anticipation of jb01 and jb02 HA configuration being setup. So, when you configure HA on jb01 and jb02, please let us know so that we can be available to help.
