With the 2025 [[infrastructure renewal]] it will become possible to schedule a fraction of a GPU using [[multi-instance GPU]] technology. Different jobs, potentially belonging to different users, can run on the same GPU at the same time. Following [https://docs.nvidia.com/datacenter/tesla/mig-user-guide/#terminology NVidia's terminology], a fraction of a GPU allocated to a single job is called a "GPU instance", also sometimes called a "MIG instance". | With the 2025 [[infrastructure renewal]] it will become possible to schedule a fraction of a GPU using [[multi-instance GPU]] technology.

The following table lists the GPU models and instances that can be selected in the CCDB form for RAC 2025. RGU values for GPU instances have been estimated from whole-GPU performance numbers and the fraction of the GPU which comprises the instance. | The following table lists the GPU models and instances that can be selected in the CCDB form for RAC 2025.

Note: a GPU instance of profile <b>1g</b> is worth 1/7 of a A100 or H100 GPU. The case of <b>3g</b> takes into consideration the extra amount of memory per <b>g</b>. | Note: a GPU instance of profile <b>1g</b> is worth 1/7 of a A100 or H100 GPU.
