System requirements

In principle, BDF support all Unix-like platforms. However, we strongly propose you to use BDF at Linux platform together Intel Fortran and C compiler because BDF package is developed and thoroughly tested on such platforms. System requirements of BDF is summarized as following lines:

• OS: Linux, Mac, FreeBSD, Unix
• Compiler: Fortran 90 compiler such as Intel, gfortran, g95
• Support softwares: Python, make
• Parallel environments: MPI

Configure and compile BDF package

Several steps are needed to install BDF package.

1. Set fortran and C compiler.
   • If you use bash shell, you can set fortran and c compiler:

       . $export FC=ifort
       . $export CC=gcc

   • Tips: If you ignored this step, the configure script will pick up the gfortran and gcc compiler as default.
2. Set blas and lapack library.
   • For flaxibality reason, we ask users to set blas and lapack libraries.

       . $export MATHLIB="-LMathLibDir -llapackname -lblasname"

3. Configure BDF package.
   • After setting compiler and mathematic library. You can configure BDF by command configure in BDF root directory.

       . $configure

     Configure support several parameters.

       . --enable-debug=yes[no]   Compile BDF in debug mode.
       . --enable-i8=yes[no]      Compile BDF with 64 bit integrals.
       . --enable-openmp=yes[no]  Compile BDF with OpenMP supporting.

4. Make
   • $make
5. Some typical installation
   • A 64bit machine with intel compiler and MKL library.
     • $export FC=ifort
     • $export CC=gcc
     • $export MATHILIB="-L/opt/intel -lmkl -lguide"
     • $./configure --enabale-i8=yes --enable-openmp=yes
     • $make
   • A Mac laptop with gfortran, gcc and user compiled lapack and blas library
     • $export FC=gfortran
     • $export CC=gcc $export MATHILIB="-L/Users/mike/mathlib -lblas -llapack"
     • $./configure --enabale-i8=yes --enable-openmp=yes
     • $make
