Workstation Suspension

Workstations Suspension is currently in Private Beta and select customers will be able to access it.

Suspending a Workstation

Workstation Suspension allows users to suspend a Workstation, which will power down a compute instance and save all software, configuration settings, and files to the Workstation disk. This functionality is just like powering off your computer. 

  • Suspend and Restart Workstations: it’s like turning your computer on and off (you will not be charged for hardware during suspension)
  • Workstations start-up in < 2 minutes (Applies to only restarts)
  • All software, configuration settings, and files will be saved to the Workstation so that users can pick up where they left off

Suspending a Workstation

In order to Suspend a Workstation, you can click “Suspend Workstation” from the top action icons or click the Suspend Workstation icon in the right-hand action menu.

Once you click Suspend Workstation, a drawer will appear confirming your Workstation of choice to suspend.

Before suspending a Workstation, please note the following:

  • Suspending a Workstation will not cause any data loss and you will not be charged for the compute time while your Workstation is suspended.
  • There is a minimum time of one hour before restarting a Workstation from Suspension.
    • This is a current technical limitation and we plan to eventually reduce or remove this limitation.
  • Any running applications will be stopped.

After clicking Suspend Workstation, your Workstation will go into a Suspending status. The time to suspend will vary, but will generally take 5 minutes.

Restarting from Suspension

In order to Restart your Workstation, click Restart. Restarting from Suspension will restart your Workstation compute instance and you will begin to be charged for compute again.

Once you click Restart, your Workstation will show a Restarting bar.

The time to start up the Workstation will vary but is expected to restart within 3 minutes. Note: Applies to only restart after a suspended state, and not to the first-time startup.

When you reconnect to the Workstation all software, configuration settings, and files will be saved to the Workstation so that you can pick up where you left off

Viewing Suspension Stats

In order to view how long your Workstation has been Active and Suspended, click on your hyperlinked Workstation name to bring you to the detail page. You will be able to view Suspension Stats in this detail page.

Active Time represents the time your Workstation compute instance is powered on and you are being charged for hardware compute. Suspended Time represents the time your Workstation compute instance is powered down and you are not being charged for hardware compute during this time.

In the logs, you will be able to view detailed status changes, including the current core hour summaries.

Collaboration

Users who are given shared access to a Workstation will not be able to Suspend/Restart the Workstation. This is a guardrail to give full control to the primary owner.

Pricing

At this time, Workstation Suspension is a free offering. Rescale will take on the burden of costs (such as storage) while in a suspended state. We may change the pricing mechanisms of this feature in the future.

Support & Limitations

OS: Windows 2019
Hardware: AWS CoreTypes
Max Workstation Session: 30 days
Nodes: Single-Node

Hardware

Suspension supports all single-node AWS hardware with cloud storage support (EBS). If a certain coretype does not support Suspension, you will see an error in the UI stating, “Hardware not eligible for Suspension”.

Operating System

Suspension currently supports only Windows 2019.

Software

We do not guarantee every software to work with Suspension. Our current guaranteed support is: Ansys Fluids, Ansys Mechanical, Oasys Software Suite

Suspension Time

We currently limit Workstation Suspension to a maximum of 30 days.

Run Time Continuing to Count up when Suspended

Today, Workstation run time continues to count up when Suspended. This is expected behavior, but it may appear confusing. The walltime aligns with this run time, so be sure to increase walltime so that your Workstation will not shut down when it is in a suspended state.

We plan to change this behavior to halt the run time from counting up when a Workstation is Suspended in the future, and therefore walltime as well.

FAQ

What are the benefits of Workstation Suspension?

Workstation Suspension offers a couple of benefits:

  • Workstations will start-up in < 2 minutes.
  • All software, configuration settings, and files will be saved to the Workstation so that users do not have to reconfigure a blank Workstation each time they start a machine.

When should I use Workstation Suspension?

We recommend using Workstation Suspension anytime you plan on using a Workstation again! When you suspend a Workstation, your Workstation is your computer in the cloud and allows you to save all of your configuration settings, files, and software. Additionally, you will not be charged for the hardware compute when a Workstation is suspended. Specific examples where it may come in handy:

  • You’re going home for the day, but plan on using a Workstation tomorrow
  • You regularly use a standard Workstation configuration for pre/post-processing

Can I switch hardware when I suspend a Workstation?

No, you cannot switch hardware when you suspend a Workstation today (e.g. Citrine 8 cores –> Citrine 32 cores), however, we plan to support this functionality in the future.

Can I add more software to a Workstation?

By default, you cannot add additional software to a Workstation once it has been started. If you would like the ability to add software after a Workstation has started, you can request Administrator Privileges from your Rescale representative, which will allow you to install the software yourself from within a Workstation.
