Introduction to F95

This course provides an introduction to Fortran 95, which contains many powerful features that make it a suitable language for programming scientific, engineering and numerical applications. Familiarity with a Unix or Linux environment is assumed. The course is open to all, but is mainly targeted at existing ARCHER users.


Fortran 90/95 is a modern and efficient general purpose programming language, particularly suited to numeric and scientific computation. The language offers advanced array support, and is complimented by a wealth of numerical libraries. Many large scale computing facilities offer heavily optimised Fortran compilers, making Fortran suitable for the most demanding computational tasks.

Topics include: fundamentals, program control, input and output, variables, procedures, modules, arrays.

Intended learning outcomes

On completion of this course students should be able to:

  • Understand and develop modularised Fortran programs.
  • Compile and run Fortran programs on ARCHER.


The are no prerequisites for this course, although a familiarity with a Unix or Linux environment is assumed.


Details are subject to change, but start, end and break times will stay the same.
