Flexible GPUs (fGPUs) are resources used for graphic rendering and large parallel computation in the Cloud. You can allocate fGPUs to your account and attach them to or detach them from your instances.

General Information

An fGPU is a resource that can be allocated to your account, and attached to or detached from your instances. You can attach several fGPUs to the same instance, provided that the fGPUs are the same models.

An fGPU can be in these different states:

  • allocated: The fGPU is reserved for your account.
  • attaching: The fGPU is scheduled for attachment to the specified instance. You need to stop the instance for the fGPU to reach the attached state. 
  • attached: The fGPU is used by the instance. It is considered a device connected to the instance.
  • detaching: The fGPU is scheduled for detachment from its instance. You need to stop the instance for the fGPU to reach the allocated state.

Note

When you attach an fGPU, the instance must meet the following conditions (see the table of models of fGPUs below):

  • Have less than a certain number of vCores
  • Have less than a certain amount of memory
  • Have a processor generation that is compatible with the fGPU

In addition, the instance must not be a dedicated instance.

Models of fGPUs

3DS OUTSCALE provides different models of fGPUs, with different amounts of video RAM (VRAM):

Instance Type Conversion

As with all instances, you can modify the type of an instance that has fGPUs attached to it. However, the number of attached fGPUs might be incompatible with the new instance type (number of vCores, amount of memory, and processor generation). Different behaviors occur depending on the conversion:

Old Type

New Type

Conversion Behavior
AWSAWS

All fGPUs attached to the instance are deleted.

Then as many as possible are created and attached to the converted instance.

AWSTINA

All fGPUs attached to the instance are deleted.

TINAAWS

All fGPUs attached to the instance are detached.

Then as many as possible are created and attached to the converted instance.

TINATINA

If all fGPUs attached to the instance are compatible with the new instance type, the instance is converted.

If not, a vm-specs-mismatch error is returned.

For more information on modifying instance types, see Modifying an Instance Attribute.
