# FLASH makefile definitions for Edison, a Cray XC30 machine at NERSC.

# The software stack is managed by the modules system.  The default
# programming environment is PrgEnv-intel/5.0.41.

# Load the following modules before compiling (names as of 6th Aug 13):
# * HDF5: module load cray-hdf5-parallel/1.8.11
# * PNETCDF: module load cray-parallel-netcdf/1.3.1.1

# Compilation flags
#
#  Three sets of compilation/linking flags are defined: one for optimized code
#  code ("-opt"), one for debugging ("-debug"), and one for testing ("-test").
#  Passing these flags to the setup script will cause the value associated with
#  the corresponding keys (i.e. those ending in "_OPT", "_DEBUG", or "_TEST") to
#  be incorporated into the final Makefile. For example, passing "-opt" to the
#  setup script will cause the flags following "FFLAGS_OPT" to be assigned to
#  "FFLAGS" in the final Makefile. If none of these flags are passed, the default
#  behavior will match that of the "-opt" flag.
#  In general, "-opt" is meant to optimize compilation and linking. "-debug"
#  should enable runtime bounds checking, debugger symbols, and other compiler-
#  specific debugging options. "-test" is useful for testing different
#  combinations of compiler flags particular to your individual system.

# Library specific linking

#  If a FLASH module has a 'LIBRARY xxx' line in its Config file, we need to
#  create a macro in this Makefile.h for LIB_xxx, which will be added to the
#  link line when FLASH is built.  This allows us to switch between different
#  (incompatible) libraries.  We also create a _OPT, _DEBUG, and _TEST
#  library macro to add any performance-minded libraries (like fast math),
#  depending on how FLASH was setup.
