Arch Linux

Description:

I'm running two TITAN Xp GPUs with nvidia driver version 418.56, on Arch Linux x86_64.

When I execute nvidia-smi I'm getting all the information about both of the GPUs:

+-----------------------------------------------------------------------------+
| NVIDIA-SMI 418.56 Driver Version: 418.56 CUDA Version: 10.1 |
|-------------------------------+----------------------+----------------------+
| GPU Name Persistence-M| Bus-Id Disp.A | Volatile Uncorr. ECC |
| Fan Temp Perf Pwr:Usage/Cap| Memory-Usage | GPU-Util Compute M. |
|===============================+======================+======================|
| 0 TITAN Xp Off | 00000000:17:00.0 Off | N/A |
| 23% 37C P8 9W / 250W | 2MiB / 12196MiB | 0% Default |
+-------------------------------+----------------------+----------------------+
| 1 TITAN Xp Off | 00000000:65:00.0 On | N/A |
| 26% 43C P8 20W / 250W | 251MiB / 12192MiB | 0% Default |
+-------------------------------+----------------------+----------------------+


But when I execute simple P2P bandwidth test from cuda package

/opt/cuda/samples/1_Utilities/p2pBandwidthLatencyTest/p2pBandwidthLatencyTest

my system hangs.
