This allows the current nekRS/master to run on Summit.

I've tested the following cases on gcc/7.4.0, cuda/10.2.89:

  • ethier, single node Summit
  • turbPipePeriodic, single node Summit
  • pb146, single node Summit
  • pb146, two nodes Summit
  • kershaw, single node Summit

Note this is not a true fix for (#305). However, this should allow users to run on Summit while I further investigate this issue.

I don't have access to lassen, so I am unsure if this issue is also there.

…her compilation.
