Breaking unit-tests on AMD GPU

See original GitHub issue

Describe the bug There are 15 unit-tests in the develop branch failing when AMD is used as the default device.

How To Reproduce In my setup the AMD is device 0:2. I use the thunder machine which has an AMD gfx900 GPU.

git checkout develop
make
tornado-test.py --ea --verbose -J"-Dtornado.unittests.device=0:2"
