On ARC2 there is a single general access queue that allows submission to all available compute resources.

Queue limits

In order to submit a job to the queue, the user must give an indication of the resources required. At a minimum the required runtime, or wall clock time, needs to be specified, without a runtime the job will be rejected. The maximum amount of time that can be requested is 48 hours. Jobs exceeding their requested runtime will be terminated by the scheduler.

Each node on ARC2 has a total of 32GB of memory available. The available memory can be split between cores. For example, each node can run:

• One single core, 32Gb process

OR

• Eight single core 4Gb processes

Jobs exceeding the memory requested will be terminated by the scheduler.

Queue defaults

Unless otherwise specified:

• a default of a single core is assigned to a job
• a default memory allocation of 1GB/core is assigned to a job
