Description

While GPU timing could work, timing reduction is not implemented and therefore what's printed is not correct (as it's the timings from the first rank).

Should be disabled (or if simple enough reduction should be added).

Indeed. Did not think much and set the target to the latest 2018.x in the drop-down.

I made the 2018.3 early, but it does need to exist before we make 2018.2 so that the triage process is clear to people.
