 Please keep in mind that this is also a shared machine, and more users want to use the GPU in this machine. So, allow everyone to make use of these GPUs and do not perform long runs here. Long runs should be submitted as jobs to scheduler. Please keep in mind that this is also a shared machine, and more users want to use the GPU in this machine.

 +===== Periodic reboots =====
 +
 +In order to prevent the login/interactive nodes from being filled up with temporary files and long-running processes, these nodes are rebooted every other week on Monday morning at 6:00 CE(S)T. The odd-numbered nodes (''login1'', ''interactive1'', ''gpu1'') are rebooted in odd weeks, and the even-numbered nodes (''login2'', ''interactive2'', ''gpu2'') are rebooted in even weeks.
