# Assumes icc is installed. Run this script to compile both intel fftw2, fftw3 libraries. It should install fftw3 and fftw2 in /share/apps/intel/Compiler/11.1/072/mkl

#####
# Important: must run this code as root, or it may not find the correct links, e.g., -liomp5
# It may also not able to install if it can't find icc in the path. In that case, ln -s the icc into /usr/bin or add the path for icc in root's .bashrc, then rerun this script again.
