== 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 ==

# After trying to compile a Fortran code I got the following error:
 /tmp/pgaccTlnihVRmAnZx.gpu(244): error: expression must have class type

'''Solution''':

There was an OpenACC directive that was causing the problem, which was commented out:
 !$ACC  parallel present(alpha,nitcg) 
       alpha=0
       nitcg=nitcg+1
 !$ACC  end parallel
