+# Sample: Grace Hopper Memory
+
+On Grace Hopper, NVLink-C2C makes CPU memory coherently accessible to the GPU,
+and the GPU translates addresses through the host page tables. GPU code can
+therefore work in place on pinned, managed and ordinary pageable host memory,
+and the CPU sees the results without a copy.
+
+This sample allocates one buffer from each `cuda.core` memory resource, plus a
+plain NumPy array:
+
+- `PinnedMemoryResource` on the GPU's nearest host NUMA node
+- `ManagedMemoryResource`
+- pageable memory from `np.empty()`
+- `DeviceMemoryResource`, for comparison
+
+It wraps each buffer as a CuPy array and uses standard CuPy operations, with no
+custom kernels. For each host-accessible buffer the CPU writes the input, CuPy
+doubles it and sums it on the GPU, and the CPU checks the result in the same
+memory. Device memory needs an explicit copy in each direction.
+
+`cp.from_dlpack()` imports the device and managed buffers. It does not import
+pinned (`kDLCUDAHost`) or CPU (`kDLCPU`) memory, so the sample wraps those
+pointers with `cupy.cuda.UnownedMemory`.
+
+## Requirements
+
+- A Grace Hopper system: the GPU must access pageable memory through the host
+  page tables, support concurrent managed access and support host NUMA memory
+  pools. Other systems waive with exit code 2 (configurable via
+  `CUDA_PYTHON_SAMPLE_WAIVER_EXIT_CODE`).
+- `cuda-core` 1.2.2 or newer with CUDA 13, CuPy for CUDA 13 and NumPy 2.2.5
+  or newer.
+
+```bash
+cd samples/cuda_core/graceHopperMemory
+pip install -r requirements.txt
+python graceHopperMemory.py
+```
+
+## Example Output
+
+On a GH200 480GB:
+
+```text
+Device: NVIDIA GH200 480GB, compute capability 9.0
+  host_numa_id: 0
+  pageable_memory_access_uses_host_page_tables: True
+  concurrent_managed_access: True
+  host_numa_memory_pools_supported: True
+GPU work on host-resident memory:
+  pinned, host NUMA node 0               sum=17163091968 verified on the CPU without a copy
+  managed                                sum=17163091968 verified on the CPU without a copy
+  pageable NumPy array                   sum=17163091968 verified on the CPU without a copy
+For comparison, device memory needs explicit copies:
+  device                                 verified after a device-to-host copy
+Done
+```
