#  $Name:  $
#
# Adapted from linux_amd64_ifort11+mpi_generic
#  with specific local path (=MPI_INC_DIR & NETCDF_ROOT ) for MPI & NetCDF
# Tested on jmc's laptop with MPI & Multi-Threaded
#  using intel compiler v.11.1.046 & mpich-1.2.7 (FC.11)
#                       v.12.0.4   & mpich-1.2.7 (FC.14)
#  (intel compiler, mpich & netcdf installed in /opt/intel/ )

#  Build options for the intel 11 fortran compiler with a generic MPI
# DON'T FORGET to set environment variable MPI_INC_DIR to the include
# directory of your MPI implementation

#-------
# run with OpenMP: needs to set environment var. OMP_NUM_THREADS
#    and generally, needs to increase the stack-size:
#   -  sh,bash:
#     > export OMP_NUM_THREADS=2
#     > export KMP_STACKSIZE=400m
#   - csh,tcsh:
#     > setenv OMP_NUM_THREADS 2
#     > setenv KMP_STACKSIZE 400m
#  NOTE: need to set KMP_STACKSIZE in ~/.tcshrc (but curiously, works
#  without OMP_NUM_THREADS in ~/.tcshrc).
