Building the Software

Building

Before continuing, understand that this code is intended to run on Intel hardware. It likely could see a performance boost with coprocessors. However, the idea of porting to a GPU is daunting and I instead would prefer to run the code on a Xeon Phi first to confirm my suspicions before writing that mountain of kernel code. Given this the Intel build instructions are discussed.

Prerequisites

To build it is required that one have

• CMake version at least 2.6
• A fully C11 compliant C compiler.
• A fully Fortran2008 compliant Fortran compiler.
• Intel MKL
• Intel Performance Primitives
• HDF5
• libxml2
• iniparser

To build the fully parallel software one must additionally obtain

• Message Passing Interface v3. Recommended free versions are MPICH and OpenMPI. The Fortran 2008 bindings must be available.

Configuring CMake

It can be expedient to configure CMake with a script. Though I sometimes have to run the script twice for whatever reason.

Serial GCC Build

The simplest build can be done with GCC and without MPI. An example script may look something like

#!/bin/sh
export CC=gcc
export FC=gfortran
export MKL_LIB_ROOT=/opt/intel/mkl/lib/intel64
export IPP_LIB_ROOT=/opt/intel/ipp/lib/intel64
if [ -f Makefile ]; then
   echo "Cleaning..."
   make clean
fi
if [ -f CMakeCache.txt ]; then
   echo "Removing CMakeCache.txt"
   rm CMakeCache.txt
fi
if [ -d CMakeFiles ]; then
   echo "Removing CMakeFiles"
   rm -rf CMakeFiles
fi
cmake \
-DCMAKE_INSTALL_PREFIX=./ \
-DCMAKE_C_COMPILER=gcc \
-DCMAKE_Fortran_COMPILER=gfortran \

Building

After CMake has been successfully configured one then simply types

make

in the root source directory to build the software. To install the software one then types

make install

in the root source directory.

Building the Developer Level Documentation

If Doxygen is available then the developer level documentation can be built by specifying

doxygen Doxyfile

in the root source directory.
