There are a couple of options for rebooting:

Soft reboot: login to your Research Server and reboot it as you would a regular desktop by clicking ‘Restart’.

Hard reboot: click the options button to the right of the "Open" button on the Home page and then click the "Hard Reboot" button. Hard rebooting shuts down the Research Server and restarts it after the power has been completely turned off, clearing the Research Server’s RAM and resetting the system.

If your Research Server shuts down, the Research Computing Portal will detect this and if you refresh the portal it will change the ‘Open’ button to a ‘Start’ button. Click this to start your Research Server up again. Once it has rebooted successfully, you will be able to access your Research Server again.

When you need more (or less) compute power (i.e. vCores or RAM) to carry out your research activities, you can resize your Research Server from the original size to another size that is more appropriate to your needs. Just click on the options button (to the right of the 'Open' button) to access the Research Server Options page. Then select the desired size (i.e. vCores or RAM) from the dropdown list in the “Resize” section and click “Resize”.

To reserve premium sizes (GPGPU, Big Memory, Fast Cores), create a reservation on your Research Server’s Options page. Find the reserve button, then select a size, then find a host that has availability for the dates you would like, finally add a justification for the use of the premium size. Once your reservation starts, you can then resize your Research Server to use the reserved premium size. To extend your use of the premium size, edit the length of the reservation via the options page. You can also cancel a reservation at any time. Read more about reserving premium sizes here.

If you’re not actively using your Research Server for a while and would like to preserve the state of it without deleting it, you can shelve your Research Server. This saves the state of your Research Server to disk and frees the resources up for other researchers to use, helping the to keep the service available to everyone. The saved state can then be un-shelved later when you need it again (loading your Research Server back to the state it was in before you shelved it).

Shelve your Research Server by clicking the “Shelve” button on the Research Server Options page. You can get your Research Server back by clicking the “Unshelve” button on the Home page, relaunching it with all your previous data. Read more about shelving and unshelving here.

vCPUs are portions or shares of the underlying, physical CPUs assigned to a particular Research Server. Research Servers are launched in the Melbourne Research Cloud where the physical cores are hyper-threaded. This allows a physical core to run twice as many computational tasks (threads) at a time. Unlike Researcher Desktop, no additional subscription is applied.
