# Memory-enforced GPU sharing

NVIDIA CUDA 13.4 adds an application-transparent time-sharing mode that confines each workload to a fraction of GPU memory, so an allocation above the requested size fails as it would on a smaller GPU. KAI Scheduler offers an NvFractions sharing mode from v0.18.0 that picks GPU slices and writes memory and compute mode into Pod annotations, and the new open-source gpu-fractioning operator enforces those limits on each node and measures per-fraction use.
