The standard operating system on the cluster is Redhat linux. However, another operating system can be run on the cluster using virtual images. For example, It is possible to run windows OS and windows based application on Griffith HPC. The following HowTo will outline the steps involved. There are some limitations which will be mentioned at the end.
...
e.g: qsub -I -X -q qweek_s -l walltime=01:00:00
There would be a wait time especially if enough resouces are not available. You will get a meesage like this below when the job is successfull and would be taken to the compute time for the period of the walltime.

Creating the Virtual Machine
cd /scratch/images/
The pre-installed image files are placed here:
check the vdi image file :
ls -lh *.vdi
It will show the size of the image in GB.
Make sure Windwos VM is turned off, if not sure run
virtualbox
to check and power it off if necessary.
Now you can resize the image, for example if you want to increase the disk size to 80GB (81920MB), you can use VBoxManage command to do it, here the size need to be in MB :
VBoxManage modifyhd win7-hpc.vdi --resize 81920
