Does TX2 support CUDA IPC?
I found two conflicting informations:
- CUDA 9.0.176 API doc : https://docs.nvidia.com/cuda/archive/9.0/cuda-c-programming-guide/index.html#interprocess-communication
- CUDA 10.1.168 API doc : https://docs.nvidia.com/cuda/cuda-c-programming-guide/index.html#interprocess-communication
From CUDA 9.0 doc (support by TX2 in L4T R28.3):
The IPC API is only supported for 64-bit processes on Linux and for devices of compute capability 2.0 and higher.
From CUDA 10.1 doc (version 10.1.166 supported by TX2 in L4T R32.1):
Note: CUDA IPC calls are not supported on Tegra devices.
Jetson TX2 compute capability: 6.2 (from https://developer.nvidia.com/cuda-gpus)
So what is the true information ?
