[torqueusers] Downgrading from Moab to Maui w/Torque-- any gotchas?

[Nicholas Lindberg]

Hello,

We are donating our cluster to a hospital for use doing genomics and bioinformatics. They don’t have a ton of experience with HPC so I’m setting it all up for them and then doing some of the IT remotely for a few months until they’re comfortable
 That said, we let our Moab license lapse, and they didn’t want to pay for the scheduler (don’t need all those features) so I was going to install Maui for them to use in its place. Has anybody ever downgraded from Moab to Maui and if so, anything I should watch out for?

Currently running Moab 7.2.5 with Torque 4.2.2. I know it’s an older Torque, but I’d just as assume keep Torque at the same level as it’s worked just fine for us—it’s what came with Bright Cluster Manager and was built to interact properly, etc. I built 5.0.3 at one point but never used it.

Thanks in advance.

Nick

Our two clusters work with Torque 4.2.5 and Maui 3.3.1.
We have a modest number of users, and don't need a very
rigorous job priority control, no need for preemption, and so on.
I guess Torque 4.2.2 would work as well.

As another user pointed out, '-l procs' doesn't work,
but considering what you said about the new cluster owners' needs,
that may not be essential for them, can get away with -l nodes=N:ppn=P.

Make sure you point to the Torque installation when you install Maui
--with-pbs=/Torque/installation/dir (Yes, they Maui still calls Torque "pbs".)
I also set --prefix=(directory where Maui will be installed),
and --with-spooldir= (same directory as --prefix).

In maui.cfg, make sure you have consistent values for

SERVERHOST your_torque_server_node_name

# primary admin must be first in list
ADMIN1 maui root #I created a "maui" user to run maui

# Resource Manager Definition
RMCFG[MASTER] TYPE=PBS #oh well, there comes PBS again ...

You can tweak more with Maui configuration parameters,
described in the Maui Admin Guide:
http://docs.adaptivecomputing.com/maui/

Some features of Maui work well, others not so much, but for instance,
you can set up separate queues on Torque,
attach some nodes to specific queues (assigning
node properties in the nodes' file and configuring the queue to use only
those nodes), have routing and execution queues, etc.

I hope this helps,
Gus Correa
