A common first program to write in a new language is a "Hello world" example where we print a simple line of output. In this tutorial we first look at examples written in C, C++ and Fortran. To run the examples we'll learn about interactive sessions on compute nodes, modules and compiling source code. We'll also look at examples in MATLAB, Python and R. For these we'll see how to use modules to select suitable interpreters.
Many people rely on compilers, for languages such as C, C++ and Fortran, to create executable programs from source code. Just like our source code, compilers themselves may have bugs. In this post we look at common forms of compiler bug, with examples, and what we can do when our work is affected by such an issue.
Fortran provides a variety of intrinsic representations of real numbers. In this post we look at what these representations are and how we choose a particular representation for our work.
Ford is a tool which can help document Fortran source code. Here we show how to use Ford and the value of automatic documentation generation.
