Hi Joseph, 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? -Ron ----- Original Message ----- From: Rayson Ho <[email protected]> To: [email protected] Cc: [email protected] Sent: Saturday, April 21, 2012 12:01 AM Subject: Re: [gridengine users] Transitioning from Torque/Maui to Open Grid Scheduler Hi Joseph, "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 queues. 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 further help. Rayson On Fri, Apr 20, 2012 at 11:42 PM, Joseph A.
