5.13: Alpha Linux Fortran

The alpha linux machines are currently loki, machine3, thor, freda, and tyr. You can verify you are on a linux alpha machine by:

$ uname -ms
Linux alpha

The recommended fortran compiler is the Compaq Fortran Compiler for Linux Alpha. It is accessed via the fort command. Sources with .f, .for, or .FOR suffixes are assumed to be FORTRAN 77. Sources with .f90 or .F90 suffixes are assumed to be Fortran 90 source files. This fortran compiler closely resembles the Fortran used on the Digital Unix machines (i.e. the planets). One difference is that when compiling Fortran 99 sources, the switch -assume no2underscores is generally required.

Compaq Fortran documentation is in

• file:///usr/local/doc/alphalinux/Fortran/index.html
• file:///usr/local/doc/alphalinux/Fortran/docs/cf/index.html
• file:///usr/local/doc/alphalinux/Fortran/docs/cxml/index.html
• file:///usr/local/doc/alphalinux/Fortran/docs/cpml/index.html

Man pages are invoked on the alpha linux machines via:

% man fort
% man -S3f intro

Currently available libraries include blas, lapack, nag, ncar, and netcdf. These are available in directory `/usr/local/lib'.Documentation can be found in directory `/usr/local/doc'. MP, the Message Passing Interface, is available in directory `/usr/local/mpich'. The mpich users guide is in file `/usr/local/mipch/doc/guide.ps.gz'.

Hard copies of the fortran documentation are also available.
