I'm working with Linux Mint 18.1, using the driver settings with Nvidia. I have a GTX 1050 Ti (Pascal) and GTX 750 Ti (Maxwell) The 375 drivers are supposed to recognize both, but don't seem to. Eventually, I'll want to put the third Nvidia card back in. nvidia-smi Tue Jun 6 00:37:27 2017 +-----------------------------------------------------------------------------+ | NVIDIA-SMI 375.66 Driver Version: 375.66 | |-------------------------------+----------------------+----------------------+ | GPU Name Persistence-M| Bus-Id Disp.A | Volatile Uncorr.

Mint 18.1 seems a bit better behaved than 17.2 or 18.0, But I'm not sure what is missing. |

All three VGA devices seem to show appropriately. $ lspci | grep VGA 00:02.0 VGA compatible controller: Intel Corporation Xeon E3-1200 v3/4th Gen Core Processor Integrated Graphics Controller (rev 06) 01:00.0 VGA compatible controller: NVIDIA Corporation Device 1c82 (rev a1) 02:00.0 VGA compatible controller: NVIDIA Corporation GM107 [GeForce GTX 750 Ti] (rev a2) |

Found what was missing: The use_all_gpus setting in the cc_config.xml (/var/lib/boinc-client/cc_config.xml) was missing. Now I'm using all of my cude cores: <use_all_gpus>1</use_all_gpus> Wed 07 Jun 2017 02:56:35 AM EDT | | CUDA: NVIDIA GPU 0: GeForce GTX 1050 Ti (driver version 375.66, CUDA version 8.0, compute capability 6.1, 4039MB, 3994MB available, 2274 GFLOPS peak) Wed 07 Jun 2017 02:56:35 AM EDT | | CUDA: NVIDIA GPU 1: GeForce GTX 750 Ti (driver version 375.66, CUDA version 8.0, compute capability 5.0, 2001MB, 1973MB available, 1606 GFLOPS peak) Wed 07 Jun 2017 02:56:35 AM EDT | | OpenCL: NVIDIA GPU 0: GeForce GTX 1050 Ti (driver version 375.66, device version OpenCL 1.2 CUDA, 4039MB, 3994MB available, 2274 GFLOPS peak) Wed 07 Jun 2017 02:56:35 AM EDT | | OpenCL: NVIDIA GPU 1: GeForce GTX 750 Ti (driver version 375.66, device version OpenCL 1.2 CUDA, 2001MB, 1973MB available, 1606 GFLOPS peak) Wed 07 Jun 2017 02:56:35 AM EDT | | [coproc] NVIDIA library reports 2 GPUs [/code] |
