How do I Install MOAB 9.x on top of Bright?

(Tested on Bright 7.3 with torque 6.0.1)

1. Download MOAB sources from Adaptive website and extract it on the head node:[root@ma-b73-c7 ~]# tar -xzvf moab-9.1.0-el7.tar.gz

2. Change into the extracted MOAB folder and configure the sources with the required configuration parameters. A sample configuration could be as follows:
[root@ma-b73-c7 ~]# cd moab-9.1.0-el7
[root@ma-b73-c7 moab-9.1.0-el7]# ./configure --prefix=/cm/shared/apps/moab --with-init --with-modulefiles=/cm/local/modulefiles --with-ipmi --with-knl --with-homedir=/cm/shared/apps/moab
------------------------------------------------------------------------
moab 9.0.2:  Configure successful.

Configuration:
   Install Directory: /cm/shared/apps/moab
   Home Directory   : /cm/shared/apps/moab
   Server Host      : ma-b73-c7
   Server Port      : 42559
   Primary Admin    : root
   Machine Name     : pbs
   With Web Services: 
   With Insight     : 

Next:

   Type ‘make install’ as root to install moab.

Attention:

    You have specified a non-default home directory (/cm/shared/apps/moab).
    You must set MOABHOMEDIR=/cm/shared/apps/moab in your environment when
    starting moab or using moab commands.

3. Install MOAB:
[root@ma-b73-c7 moab-9.1.0-el7]# make install
[...]

4. Modify the MOAB configuration to point to Torque:
[root@ma-b73-c7 moab-9.1.0-el7]# grep RMC /cm/shared/apps/moab/etc/moab.cfg 
RMCFG[torque]      TYPE=TORQUE SUBMITCMD=/cm/shared/apps/torque/current/bin/qsub

5. Configure dynamic linker run-time bindings:
[root@ma-b73-c7 moab-9.1.0-el7]# cat > /etc/ld.so.conf.d/moab.conf
/cm/shared/apps/torque/current/lib
/cm/shared/apps/moab/lib
[root@ma-b73-c7 moab-9.1.0-el7]# ldconfig 
[root@ma-b73-c7 moab-9.1.0-el7]# 

6. Copy the license:
[root@ma-b73-c7 moab-9.1.0-el7]# cp /root/moab.lic /cm/shared/apps/moab/etc/

7. Edit /lib/systemd/system/moab.service to append the required environment variable:
[root@ma-b73-c7 moab-9.1.0-el7]# grep Env /lib/systemd/system/moab.service
Environment=PATH=/sbin:/bin:/usr/sbin:/usr/bin MOABHOMEDIR=/cm/shared/apps/moab

8. Enable Torque/MOAB via Bright:
[root@ma-b73-c7 moab-9.1.0-el7]# wlm-setup -w torquemoab -s
