Ubuntu + AMDGPUPRO results ?

[skn123]

I don't think I am able to understand these results. Do they make sense?

Could you please restate your question? I'm afraid I don't know what you are asking here.

[skn123]

The numbers didnt come out correctly After doing NMF.. I get the following: W*H [7,6] ((0,0,0,0,0,0),(0,0,0,0,0,0),(0,0,0,0,0,0),(0,0,0,0,0,0),(0,0,0,0,0,0),(0,0,0,0,0,0),(0,0,0,0,0,0)) Is this correct? The host and device tests look plausible

karl, please reformat my question. I am unable to reformat it myself :(

[karlrupp]

Oh, this doesn't sound reasonable. If possible, can you run tests/nmf-test-opencl? It requires ENABLE_TESTING to be activated in CMake and also uBLAS to be available on the system.
