Advanced Fortran Topics

This course, a PRACE training event, is targeted at scientists who wish to extend their knowledge of Fortran to cover advanced features of the language.

Topics covered include:

• Best Practices
  • global objects and interfaces
  • abstract interfaces and the IMPORT statement
  • object based programming
• Object-Oriented Programming
  • type extension, polymorphism and inheritance
  • binding of procedures to types and objects
  • generic type-bound procedures
  • abstract types and deferred bindings
• Fortran 2003 I/O extensions, especially user-defined derived type I/O
• OO Design Patterns: application of object-oriented programming
  • creation and destruction of objects
  • polymorphic objects and function arguments
  • interacting objects
  • dependency inversion: submodules and plugins
• IEEE features and floating point exceptions (omitted in the 2020 iteration)
• Interoperability with C
  • mixed language programming patterns
• Coarrays
  • PGAS concepts and coarray basics
  • dynamic entities
  • advanced synchronization
  • parallel programming patterns
  • recent enhancements: collectives, events, teams, atomic subroutines
  • performance aspects of coarray programming

To consolidate the lecture material, each day's lectures are complemented by hands-on sessions.
