# Parallel SCHISM Makefile
#
# User makes environment settings for particular OS / PLATFORM / COMPILER / MPI
# below as well as setting flags having to do with included algorithms (e.g. sediment)
# and the compiler configuration (debug, timing). 
#
# The environment settings are based on the following options.
#
# Compiler name:
#   FCS: Serial compiler (for utilities)
#   FCP: Parallel compiler
#   FLD: Linker (in general same as parallel compiler)
#
# Compilation flags
#   FCSFLAGS: Flags for serial compilation
#   FCPFLAGS: Flags for parallel compilation (including all pre-processing flags)
#   FLDFLAGS: Flags for linker (e.g., -O2)
#
# Preprocessor flags:
#   DEBUG: Enable debugging code
#   ORDERED_SUM: Enable globally ordered sums & dot-products for bit reproducibility
#     of state quantities independent of number of processors (note: this can
#     significantly degrade performance);
#   INCLUDE_TIMING: Enable wallclock timing of code (note: this can have slight
#     effect on performance);
#   MPI_VERSION = 1 or 2: Version of MPI (try 2 first, if compile fails due to mpi
#     related errors then switch to version 1;
#
# Libraries (needed for parallel code)
#   MTSLIBS: Flags for linking ParMeTiS/MeTiS libaries
