     1== QCG BES/AR on separate Machine = 
     2 
     3If you plan to install the Smoa Computing (QCG BES/AR) service on a separate machine (for performance or security reasons) you must assure that: 
     4* the machine is a submit host of the Torque Local Resource Manager, what further implies that: 
     5 * the machine share account information with the whole cluster (e.g. using LDAP or NIS), 
     6 * the torque-client and torque-devel packages are installed, 
     7 * the contents of the `/var/spool/pbs/server_name` points to the machine where the Torque `pbs_server` is running. 
     8 * the Smoa Computing host is added as `submit_host` in the Torque server configuration:

     15  set server submit_hosts += qcg.your.domain 
     16  set server submit_hosts += qcg 
     17}}} 
     18}}} 
     19  '''Note:''' You may need to add the Smoa Computing host in the `/etc/hosts.equiv` file. 
     20 
     21* the machine mounts `/home` filesystem of the cluster. Alternatively you can mount any other file system that can be used by any user (e.g. the scratch filesystem). 
     22* the `/var/spool/pbs/server_logs` directory is exported in read-only mode (e.g. using NFS or Lustre) from Torque server to this machine (this share must be mounted locally as `/var/spool/pbs/server_logs`). The Torque DRMAA library for scalability reason can be configured to use batch system logs to get notified about jobs state changes. 
     23* the machine is administrative host of the Maui Scheduler, what further denotes that: 
     24 * The maui-client package is installed. 
     25 * On the Smoa Computing machine modify the `SERVERHOST` section of the `/var/spool/maui/maui.cfg` file. It must points to the machine where the maui daemon is running. 
     26 * On the Maui server machine modify the `ADMINHOSTS` section of the `/var/spool/maui/maui.cfg` file and add the Smoa Computing host to the list of admin hosts.
