#

#
# 0) Specify compiler and linker:

CXX=g++
LINKER=g++


# 1) Build with MPI or not?
#    If you want to run the program with MPI, make sure USE_MPI is set 
#    to -DUSING_MPI

#USE_MPI =
USE_MPI = -DUSING_MPI


# 2) MPI headers:  
#    If you:
#    - Are building MPI mode (-DUSING_MPI is set above).
#    - Do not have the MPI headers installed a default search directory and
#    - Are not using MPI compiler wrappers
#    Then specify the path to your MPI header file (include a -I)

MPI_INC = -I/usr/MPICH/SDK.gcc/include


# 3) Specify C++ compiler optimization flags (if any)
#    Typically some reasonably high level of optimization should be used to 
#    enhance performance.

#IA32 with GCC: 
#CPP_OPT_FLAGS = -O3 -funroll-all-loops -malign-double

CPP_OPT_FLAGS = -O3 -funroll-all-loops

#
# 4) MPI library:
#    If you:
#    - Are building MPI mode (-DUSING_MPI is set above).
#    - Do not have the MPI library installed a default search directory and
#    - Are not using MPI compiler wrappers for linking
#    Then specify the path to your MPI library (include -L and -l directives)

MPI_LIB = -L/usr/MPICH/SDK.gcc/lib -lmpich

#
# 5) System libraries:

SYS_LIB = -lg2c -lm

#
# 6) Specify name if executable (optional):

TARGET = test_HPCCG
