Compiling CESM for intel MIC in offload mode

[aketh_t_]

Hi All,

I am trying to run CESM(community earth system model written in Fortran) with offload sections for Intel Xeon Phi. I am trying to do this for an OpenMP loop present in a section called baroclinic function. While doing this, I get the following error during compilation of the offload code. 

A procedure called by a procedure with the OFFLOAD:TARGET attribute must have the OFFLOAD:TARGET attribute.

I am also getting this error for Global variables. I tried adding the attributes "offload: mic :: <function name>" and "offload: mic :: <variable name>". This solves the problem. However, the hierarchical calls go down to almost 7-8 levels and doing this for every function and variable is too tedious. 

How to go about this? Is there any workaround?

Thanks,

Aketh

Adding "-qoffload-attribute-target=mic" to the compiler command line will cause all functions and variables to be compiled as it they had the been explicitly declared with the offload attribute.
