=================== Sharing CUDA Memory =================== .. _cuda-ipc-memory: Sharing between process ======================= .. warning:: This feature is limited to Linux only. Export device array to another process -------------------------------------- A device array can be shared with another process in the same machine using the CUDA IPC API. To do so, use the ``.get_ipc_handle()`` method on the device array to get a ``IpcArrayHandle`` object, which can be transferred to another process. .. automethod:: numba.cuda.cudadrv.devicearray.DeviceNDArray.get_ipc_handle .. autoclass:: numba.cuda.cudadrv.devicearray.IpcArrayHandle :members: open, close Import IPC memory from another process -------------------------------------- The following function is used to open IPC handle from another process as a device array. .. automethod:: numba.cuda.open_ipc_array
