Parallel programming is a huge, exciting and evolving field. Together with my guest Marc Hartung from Dive in Berlin, Germany, we try to cover some aspects of it: including OpenMP, how to synchronise data etc. Links: https://en.cppreference.com/w/cpp/language/memory_model the C++ memory model https://www.openmp.org OpenMP home page https://www.open…

How can we measure the performance (run-time, memory usage etc) of our C++ code? And what does performance mean, anyway. These and other questions are the topic of this episode - with my guest Klaus Iglberger, C++ engineer, tutor and mentor.

Software libraries play a crucial role in software development, and C++ is no exception. Klaus and I walk through the different aspects of building, using and selecting libraries.

Here we touch on some ways to build classes in C++ and how class design such as class hierarchies can help to make code more readable, more maintainable and less error prone (amongst other things). Klaus Iglberger and I also touch on design patterns and briefly what other programming paradigms exist apart from object oriented programming (OOP). Lin…

Inheritance, templates, function overloading - they all fall into the category of polymorphism in programming. My guest Klaus Iglberger and I discuss the different aspects of how this could be done with C++.

Exceptions are essentials, as are error codes. Writes Bjarnes Stroustrup. And so on our 3rd stop through C++ I talk about what you could do when things go wrong. And what you can do to prevent errors - with testing. My guest is, again Klaus Iglberger. The sounds you're hearing are from the excellent https://sound-effects.bbcrewind.co.uk BBC sound l…

In the beginnings were...data and data types. Which is where we begin our journey through C++. The language provides for a range of interesting, fundamental, complex and custom types - one of which is a set of pointer types. My guest in this episode is Marc Hartung from Dive in Berlin, Germany. Links: https://en.wikipedia.org/wiki/Pointer_(computer…

This first episode is about introducing C++, where it started, how it evolved. You will hear from 2 practitioners: Klaus Iglberger (C++ coach/trainer) and Marc Hartung (tech lead at Dive in Berlin). Here are a few links for you to follow up on: https://www.stroustrup.com The Home Page of Bjarne Stroustrup who created C++. There are plenty of links …

Welcome to the new podcast from the Advanced Research Computing Centre of the University College London, UK. A companion podcast for courses on Research Computing at UCL. In this first season we'll be presenting the course on Research Computing with C++. And this short teaser explains how it all works. Have fun! Don't be shy - say Hi This podcast i…
