error in offload directive in fortran

[aketh_t_]

hi all,

i have been trying to add a small OFFLOAD section to a program in CESM.

however i get the following error on compilation.

!dir$ end offload

i have added the source code here as an attachment for reference.

You are just missing the BEGIN keyword. The syntax of the OFFLOAD BEGIN/END directives for your code would be:

    !dir$ offload begin target(mic)
    write(*,*) "CAM atmosphere model initialization"     
    !dir$ end offload

If you need more details, refer OFFLOAD BEGIN and END OFFLOAD in the User's Guide.

thank you that worked now the error seems to be in linking the MIC.

/home/aketh/cesm/cases/B_mic/exe/lib//libatm.a(atm_comp_mct.o): In function `atm_comp_mct_mp_atm_write_srfrest_mct_':

any help.

this error is thrown by this command.
