  • Test suite not using NVIDIA pci-passthrough on VMware

    Hi,

    I'd like to do some benchmarks on a virtual machine under Vmware (vSphere 6.7u1), but looks like Phoronix Test Suite is trying to use the default Video Card instead the NVIDIA connected using PCI-Passthrough.

    Using 'nvtop' I see the following:
    Code:
     Device 0 [Tesla V100-PCIE-16GB] PCIe GEN [email protected] RX: 0.000 kB/s TX: 0.000 kB/s
     GPU 135MHz  MEM 877MHz  TEMP  44°C FAN N/A% POW  28 / 250 W
    Or, by using nvidia-smi:

    Code:
    +-----------------------------------------------------------------------------+

    However, Test Suite fails on CUDA tests. Here's the output when using 'diagnostics':

    Any way to 'force' test suite to use the pci-passthrough device?




    Thanks and kind regards,
