What both publish
| Fact | Apptainer | Enroot |
|---|---|---|
| GPU support | Apptainer supports NVIDIA CUDA, AMD ROCm, Intel Gaudi, and OCI Container Device Interface accelerators. | Built-in GPU support uses libnvidia-container, and the optional GPU requirements include NVIDIA drivers version 361.93 or later and libnvidia-container-tools version 1.0 or later. |
| Linux requirements | Full functionality requires kernel support for FUSE and unprivileged user namespaces; some features require additional software such as BuildKit or IPFS. | Enroot requires Linux kernel 3.10 or later and kernel support for namespaces, user namespaces, and seccomp filters. |
