Compiling and installing FFTW 3.3.3 with OpenMPI and OpenMP

To Compile FFTW 3.3.3 single precision with OpenMPI, make sure you compile and set your path for Intel and OpenMPI.  

Step 1: Compiling FFTW 3.3.3 (Single Precision) with OpenMPI and OpenMP.
After unpacking FFTW 3.3.3, you may want to use the flags

# ./configure CC=icc 
--enable-float --enable-threads --enable-openmp \
--enable-mpi MPICC=mpicc \
LDFLAGS=-L/usr/local/openmpi/intel/lib CPPFLAGS=-I/usr/local/openmpi/intel/include \ 
--prefix=/usr/local/fftw-3.3.3-single
# make -j8
# make install

Inside /usr/local/fftw-3.3.3-single/lib, you should see at least the files below

libfftw3f.a
libfftw3f_mpi.a
libfftw3f_omp.a
libfftw3f_threads.a
....
....

Step 2: Compiling FFTW 3.3.3 (Double Precision) with OpenMPI and OpenMP

# ./configure CC=icc 
--enable-threads --enable-openmp \
--enable-mpi MPICC=mpicc \
LDFLAGS=-L/usr/local/openmpi/intel/lib CPPFLAGS=-I/usr/local/openmpi/intel/include \ 
--prefix=/usr/local/fftw-3.3.3-single
# make -j8
# make install

Inside /usr/local/fftw-3.3.3-double/lib, you should see at least the files below

libfftw3.a
libfftw3_mpi.a
libfftw3_omp.a
libfftw3_threads.a
....
....
