5.14: Linux Fortran

For the results of a study of Linux Fortran compilers made here during February 2000 see: https://w3.pppl.gov/~dmccune/papers-reports/linux_f90.txt

Available on the Linux Intel members of the Unix Cluster are:

1. Fujitsu Fortran
2. Lahey-Fujitsu Fortran
3. Portland Group Fortran
4. Numerical Algorithms Group (NAG) Fortran
5. Message Passing interface (MPI)
6. Fortran specific libraries such as blas, lapack, nag, and netcdf.

A description follows.

1. The Fujitsu Fortran Linux compiler is invoked via:

    % setenv PATH            /usr/local/ffc/bin:$PATH
    % setenv LD_LIBRARY_PATH /usr/local/ffc/lib
    % f90 -o test_example test_example.f
   

   • frt, f90, and f95 are equivalent commands used to compile
   • The Fujitsu debugger is invoked via fdb
   • Fujitsu Fortran specific libraries are in /usr/local/ffc/lib/...

   See the following for Fujitsu Fortran documentaion

   • User and Reference manuals are in /usr/local/ffc/doc/...
   • Man pages are in /usr/local/ffc/man. As an example, to obtain documentation on program f90 or on subroutine ifix:

      % man -M /usr/local/ffc/man f90
      % man -M /usr/local/ffc/man ifix 
     

     Available subroutines can be listed via:

      % ls /usr/local/ffc/man/man3
     

   • Vendor web site is at http://www.fujitsufortran.com

2. The Lahey-Fujitsu Fortran Linux compiler is invoked via:

    % setenv PATH            /usr/local/lff95/bin:$PATH
    % setenv LD_LIBRARY_PATH /usr/local/lff95/lib
    % lf95 -o test_example test_example.f
   

   • lf95 is the command used to compile
   • The Lahey-Fujitsu debugger is invoked via fdb
   • Lahey-Fujitsu Fortran specific libraries are in /usr/local/lff95/lib/...

   See the following for Lahey-Fujitsu Fortran documentaion

   • User and Reference manuals are in /usr/local/lff95/doc/...
   • Man pages are in /usr/local/lff95/man. As an example, to obtain documentation on program lf95 or on subroutine ifix:

      % man -M /usr/local/lff95/man lf95
      % man -M /usr/local/lff95/man ifix 
     

     Available subroutines can be listed via:

      % ls /usr/local/lff95/man/man3
     

   • Vendor web site is at http://www.laheyonline.com

3. The Portland Group Fortran Linux compiler is invoked via:

    % setenv PATH            /usr/local/pgf90/bin:$PATH
    % setenv LD_LIBRARY_PATH /usr/local/pgf90/lib
    % f90 -o test_example test_example.f
   

   • f90 or pgf90 are equivalent commands used to compile.
   • totalview will invoke the TotalView debugger.
   • The Portland Group F90 Fortran specific libraries are in /usr/local/pgf90/lib.

   See the following for Portland Group Fortran documentation

   • man pages at: pgf77(1), pgf90(1). pghpf(1), pgprof(1), pgdbg(1), and Xpgdbg(1).
   • Vendor documenation at: /usr/local/pgf90/doc/....
   • Vendor WEB documentation at: https://w3.pppl.gov/misc/pgi.
   • Vendor web site at: http://www.pgroup.com.

4. The NAG Fortran compiler is invoked via:

    % setenv PATH            /usr/local/nagf95/bin:$PATH
    % setenv LD_LIBRARY_PATH /usr/local/nagf95/lib
    % f95 -o test_example test_example.f
   

   • f77, f90, and f95 are equivalent commands used to compile.
   • dbx90 will invoke the dbx debugger.
   • The NAG F95 Fortran specific libraries are in /usr/local/nagf95/lib.

   See the following for NAG Fortran documentation

   • Man pages are in /usr/local/nagf95/man. As an example, to obtain documentation on program f95:

      % man -M /usr/local/nagf95/man f95
     

   • Vendor web site at: http://www.nag.com.

5. The Message Passing Interface

   MPI, the Message Passing Interface, is specific to each Fortran compiler. Depending of the compiler use either /usr/local/ffc/mpich/... , /usr/local/lff95/mpich-1.2.1/... /usr/local/pgf90/mpich-1.2.1/..., or /usr/local/nagf95/mpich-1.2.1/...

   See the following for Message Passing Interface documentation

   • A Users Guide is at `/usr/local/ffc/mpich/doc/guide.ps.gz'
   • Man pages are in /usr/local/ffc/mpich/man. As an example, to obtain documentation on program mpif90 or on subroutine MPI_Bcast:

       % man -M /usr/local/ffc/mpich/man mpif90
       % man -M /usr/local/ffc/mpich/man MPI_Bcast
     

     Names of available MPI man pages can be listed via:

       % man -M /usr/local/ffc/mpicn/man -k MPI
     

   • WEB documentation is at

     http://www-unix.mcs.anl.gov/mpi/index.html

     http://WWW.ERC.MsState.Edu/labs/hpcl/projects/mpi/

6. Fortran specific libraries

   Fortran libraries specific to each Fortran compiler are in /usr/local/ffc/lib, /usr/local/lff95/lib, /usr/local/pgf90/lib, and /usr/local/nagf95/lib .

   Current available libraries include blas, lapack, nag, and netcdf.
