**The qexp queue is equipped with nodes that do not have exactly the same CPU clock speed.** Should you need the nodes to have exactly the same CPU speed, you have to select the proper nodes during the PSB job submission.
***qexp**, the Express queue: This queue is dedicated to testing and running very small jobs. It is not required to specify a project to enter the qexp. There are always 2 nodes reserved for this queue (w/o accelerators), a maximum 8 nodes are available via the qexp for a particular user. The nodes may be allocated on a per core basis. No special authorization is required to use qexp. The maximum runtime in qexp is 1 hour.

***qprod**, the Production queue: This queue is intended for normal production runs. It is required that an active project with nonzero remaining resources is specified to enter the qprod. All nodes may be accessed via the qprod queue, except the reserved ones. 187 nodes without accelerators are included. Full nodes, 36 cores per node, are allocated. The queue runs with medium priority and no special authorization is required to use it. The maximum runtime in qprod is 48 hours.

***qlong**, the Long queue: This queue is intended for long production runs. It is required that an active project with nonzero remaining resources is specified to enter the qlong. Only 20 nodes without acceleration may be accessed via the qlong queue. Full nodes, 36 cores per node, are allocated. The queue runs with medium priority and no special authorization is required to use it. The maximum runtime in qlong is 144 hours (three times that of the standard qprod time - 3 x 48 h).
