[gridengine users] Transitioning from Torque/Maui to Open Grid Scheduler

The biggest difference between Grid Engine & Torque is the concept of "queue",
as mentioned by Rayson.
The rest are much easier to understand or migrate. You can expect same or very
similar limits (stack, runtime, etc) offered by both queueing systems.
And do you have any specific settings for your nodes?

"Queues" in Grid Engine (and Open Grid Scheduler/Grid Engine) and the
ones Torque/Maui have slightly different meaning.
In Grid Engine, jobs are not submitted to "queues", but rather jobs
are submitted to the global waiting area. Then the scheduler picks
"queue instances" (queue instances roughly = hosts, yet each host can
have more than 1 queue instance) that satisfy the resource
requirements of each job, and at that point they are binded to the
We also have global queues called "cluster queues", but they are
abstraction of the queue instances.
So what does that all mean??
In LSF or Torque, some clusters have debug queues, short queues, long
queues, etc. Those can be migrated to Grid Engine cluster queues with
some work (ie. relatively easy).
If you want queue level user-based fairshare or queue-based fairshare
in LSF (eg. users in each queue gets a different priority) - I have
not looked at Maui for a while, not sure if it has this feature, then
it can be harder to implement or model in Grid Engine.
If you let us know a bit more about your setup, then we can provide
