Getting Started
Logging in.
To log in to the cluster, ssh to
gowonda.rcs.griffith.edu.au
What is ssh
SSH Secure Shell provides users with a secure, encrypted mechanism to log into systems and transfer files
ssh clients
windows platform
To use X11 port forwarding, Install Xming X Server for Windows first.
See instructions here
If X11 forwading is not needed (true for most cases), do not install it.
To install a ssh client e.g. putty, please follow this instruction
Linux platform and mac platform
ssh -Y gowonda.rcs.griffith.edu.au
Transferring files between your desktop and gowonda cluster
Once you are on the system, have a look around. Your home directory is stored in:
/exports/home/<SNumber>
where you have 50GB of allocated space.
Work space is available at:
/scratch/<snumber>
which is a "scratch" area for short lived data. All data older than one week is deleted from this folder.
You should not read or write directly into your home directory with submitted jobs - they should always use the "/scratch/<snumber>" filesystem
Running Jobs
We provide modules that set up the environments you need to use for specific packages. You can see what modules are available with the command:
module available
and you can load them with the command:
module load MODULENAME
See sample pbs scripts here.
If you don't specify a maximum runtime, you will end up with a maximum runtime as short as 30 minutes, depending on which node your job runs on.
Job State
when you run qstat from the command line, you will see your job's state within the queue. The following form lists the possible states and their descriptions
state code | State description |
|---|---|
q | queued |
r | running |
