# Makefile to compile the Material subroutine for BVP solution using spectral method
#
# use switch on make to determine PRECISION, e.g make PRECISION=single
# default is PRECISION=double
# be sure to remove all librarys with different PRECISION (make clean)
# 
# Uses openmp to parallelise the material subroutines (set number of cores with "export MPIE_NUM_THREADS=n" to n)
# Uses linux threads to parallelise fftw3 (should also be possible with openmp)
# Besides of the f90 files written at MPIE, the two library files of fftw3 "libfftw3_threads.a" "libfftw3.a" are also needed
# Install fftw3 (v3.2.2 is tested) with "./configure --enable-threads --enable-float"  and "make", "make install" is not needed
# as long as the two library files are copied to the source code directory.

# OPTIONS = standart (alternative): meaning
#-------------------------------------------------------------
# PRECISION = double (single): floating point precision
# F90 = ifort (gfortran): compiler, choose Intel or GNU
# VERSION = 10 (12): version of Intel compiler. More aggressive optimization if VERSION =12
# PORTABLE = TRUE (FALSE): decision, if executable is optimized for the machine on which it was built
