# Parallel Fortran:
#
# For CG, EP, FT, MG, LU, SP, BT and UA, which are in Fortran, the following 
# must be defined:
#
# F77        - Fortran compiler
# FFLAGS     - Fortran compilation arguments
# F_INC      - any -I arguments required for compiling Fortran 
# FLINK      - Fortran linker
# FLINKFLAGS - Fortran linker arguments
# F_LIB      - any -L and -l arguments required for linking Fortran 
# 
# compilations are done with $(F77) $(F_INC) $(FFLAGS) or
#                            $(F77) $(FFLAGS)
# linking is done with       $(FLINK) $(F_LIB) $(FLINKFLAGS)

# Parallel C:
#
# For IS and DC, which are in C, the following must be defined:

# CFLAGS     - C compilation arguments
# C_INC      - any -I arguments required for compiling C 
# CLINK      - C linker

# C_LIB      - any -L and -l arguments required for linking C

# Global *compile time* flags for C programs
# DC inspects the following flags (preceded by "-D"):
#
# IN_CORE - computes all views and checksums in main memory (if there is 
# enough memory)
#
# VIEW_FILE_OUTPUT - forces DC to write the generated views to disk
#
# OPTIMIZATION - turns on some nonstandard DC optimizations
#
# _FILE_OFFSET_BITS=64 
# _LARGEFILE64_SOURCE - are standard compiler flags which allow to work with 
# files larger than 2GB.

# Utilities C:

# This is the C compiler used to compile C utilities.  Flags required by 
# this compiler go here also; typically there are few flags required; hence 
# there are no separate macros provided for such flags.
