Interactive / Batch Use
The batchsystem is running continuously unless any reservations of
the graphical subsystems have been made between 08:30 - 20:00 Monday
to Friday. During this time Lustig is configured for
interactive use and users that utilise Lustig's visualisation
systems have priority. If a reservation has been made, the batchsystem is
stopped automatically by a script before the scheduled time begins. If
a booking is made at the current time, the batchsystem is stopped
within 2 minutes. However, batch jobs may be started by administrator
during scheduled time if the interactive use is low or if all current
interactive users agree.
During nights (20:00 - 08:30)
and weekends batch jobs have priority and the batchsystem is not
stopped even if a booking has been made. Jobs can be submitted to
Lustig's queueing system at any time.
Portable Batch System (PBS) is used for queueing
batch jobs.
File Systems
There are two file systems that are available for user files:
- /home
- Where your $HOME is located. This file system is backed up on a
regular basis. Please, do not put large output data files here that
can easily be reproduced. Instead, put large data file on
- /scratch
(a symbolic link to /disk/fast/scratch)
- This is a large and fast file system for temporary output data storage.
There is no cleaning policy established
yet so your files will currently remain
there until you remove them. When the number of allocated blocks
gets closer to 100%, we will have to start to remove old files.
To avoid file name collisions; create your own directory in which you put all
your files.
Note:
This file system is not backed up.
