Dear all,

I just compiled VASP OpenACC (see attached makefile.include) and sucessfully run all tests.
However, I see a lot of ieee floating point warnings:

Warning: ieee_invalid is signaling
Warning: ieee_divide_by_zero is signaling
Warning: ieee_overflow is signaling
Warning: ieee_underflow is signaling
Warning: ieee_inexact is signaling
FORTRAN STOP

Is this already known? It does not seem to effect the results:

SUCCESS: ALL SELECTED TESTS PASSED

We are aware that running the code with all checks enabled will raise some warnings. However if your tests run and produce the expected results, the code should be setup properly.
