Half of GPU VRAM available to OpenCL under Linux ?

Question asked by madscientist159 on Feb 7, 2018

We purchased a couple of WX4100 4GB cards with the understanding that we could use OpenCL applications requiring at least 3GB of on-card RAM.  Instead, the amdgpu-pro driver under Ubuntu 16.04 is only reporting 2GB of RAM, and our applications will not run.

 

Is there a way to allocate more VRAM to OpenCL under Linux, or do we need to reevaluate the purchase at this point?
