Compiling the code with OpenACC support

In order to find the correct flags for the compiler run: 

pgaccelinfo

The flags are in the last output line. Example: 

pgicc/pgfortran -ta=tesla:cc35

Note: Don't forget to add the OpenACC flags to the linker: 

pgicc/pgfortran -acc -acclibs

Issues met

/tmp/pgaccTlnihVRmAnZx.gpu(244): error: expression must have class type
