NAGWare Fortran Compiler

This document informs about installation and usage of the NAGWare Fortran compiler on LRZ computing platforms.

Introductory Remarks

LRZ has a licensing contract with NAG which enables using its the Fortran compiler product on the x86_64 Linux cluster. It supports a large subset of the features described in the Fortran 2003 standard; in particular, object-oriented programming using type-bound procedures, unlimited polymorphic entities and allocatable scalars is supported.

Usage

Before using the compiler, please first set up the required environment by loading the appropriate environment module:


module unload fortran
module load fortran/nag

The compiler is then available via the nagfor command.

Documentation

Once the fortran/nag environment module is loaded, the following man 1 pages (among others) become available: nagfor, nagfmcheck, fpp, dbx90.

The variable $NAG_DOC points at a directory containing documentation in PDF format.

In case of problems please contact HPC support at LRZ.
