we are currently running Moab on our Cray XT4 and connect it to Gold on
our Cray SMW workstation. We let Moab on the sdb-node talk to a port on
the boot-node which is forwarded with iptables to the SMW.
We have this line in moab.cfg:
AMCFG[bank] TYPE=GOLD HOST=boot PORT=7112 SOCKETPROTOCOL=HTTP
In addition you need the CLIENTCFG[AM:bank]... line in moab-private.cfg.
We installed gold (client) in the XT and set the correct path in moabs
To avoid a high load for Moab/Gold combination we have limited the
number of idle jobs in Moab (MAXIJOB) and put in place cron-jobs which
check if there are idle jobs that cannot start due to wrong cpu-account
or not enough credits (sends email to user and put job on hold).
Also, make sure that your database is tuned and vacuumed and all indexes
are in place.
Let me know if you need more information.
