 # Makefile to compile the Material subroutine for BVP solution using spectral method

 # Be sure to remove all files compiled with different options by using "make clean"
-# 
-# Uses OpenMP to parallelize the material subroutines
-# (set number of threads with "export DAMASK_NUM_THREADS=n" to n)
-#
-# Install fftw3 (v3.3 is tested):
-# + execute
-#   ./configure --enable-threads --enable-sse2 --enable-shared
-#   make
-#   make install
-# + set FFTW_ROOT in your envinronment
-#   We essentially look for two library files "lib/libfftw3_threads" and "lib/libfftw3", 
-# Uses linux threads to parallelize fftw3
-#
-# Instead of the AMD Core Math Library or the Intel Kernel Math Library 
-# a standard "lib(64)/liblapack.a/dylib/etc." can be used.
