FirePro W9100 Ubuntu 16.04 Performance Issue

Hello community,

hello AMD,

 

after a long time waiting and the interim deployment of a experimental driver,

I’ve just installed the most recent, stable AMD pro driver for Ubuntu 16.04.

 

My setup is a  headless workstation with a Radeon FirePro W9100 32GB which should be used for image processing (via opencl).

 

I’m running

  • Ubuntu 16.04
  • Kernel 4.4.0-51-generic

and I’ve installed

  • amdgpu-pro-16.40-348864
  • AMD-APP-SDK-v3.0.130.136-GA-linux64

 

The driver seemed to be installed correctly:

 

lshw -C display

  *-display             

       description: VGA compatible controller

       product: Hawaii XT GL [FirePro W9100]

       vendor: Advanced Micro Devices, Inc. [AMD/ATI]

       [….]

       configuration: driver=amdgpu latency=0

       […]

 

lspci -nnk | grep -i vga -A3 | grep 'in use'

  Kernel driver in use: amdgpu

 

However a quick test via pyopencl resulted in a benchmark which performed worse than before (with the experimental driver).

 

It seems like only 16 GB of RAM and only 14 compute units out of 44 were detected:

Device name: Hawaii

Device type: GPU

Device memory: 16192 MB

Device max clock speed: 555 MHz

Device compute units: 14

 

Running /opt/amdgpu-pro/bin/clinfo produced a rather confusing output (find attached), which leads to the assumption, that

something related to the driver might be broken.

 

Does anyone have a similar experience (or even better a solution) with the FirePro W9100 running Ubuntu 16.04?

 

Kind regards,

Dorian
