All right.

Then I'm going to introduce our guests.

You know that we had a little series of talks in the HPC Cafe about software development,

starting with an introduction to Git and some advanced Git techniques.

And today we have guest speakers from the Karlsruhe Institute of Technology, Git, Jennifer

Bukmüller and Thierry Cogent, who will tell us about continuous integration, continuous

benchmarking and continuous deployment in an HPC environment.

If you know HPC in Germany, you know that Karlsruhe has a long history of high performance

computing running systems, developing software.

So these guys know what they're talking about.

And we are very much looking forward to your presentation, Jennifer and Thierry.

Go ahead.

Okay.

Thank you very much.

Also for this kind introduction.

So add in full screen.

Oh, perfect.

Okay.

So, yeah, thank you very much also for the introduction to take part of this cafe, because

also you mentioned in those COVID kind of days, having this interaction and also talk

and discuss things without coffee in your hands getting pretty hard there.

But I think it's good to have some kind of interaction there and to exchange your experiences.

And also it's I think NHR as we started or getting started in Germany, I'm quite happy

that sustainable software development is a very important topic.

It was the topic not only from KIT, but also colleagues from Erlang and we have this very

strong point in common.

And I'm happy that we have one project.

We named it continuous access, it stands for continuous integration, deployment, testing,

but also benchmarking HPC systems.

So in the next 15 minutes, I will give you a rough tour what we have done so far at KIT

and we want extended in NHR.

And on this very first slide, you can see some glances of our new tier two system, Hureka,

that is currently set up and we fingers crossed, we hope to get there in the top 10 of Europe

in the top 500 in the next couple of days.

So we will see how that goes.

Some words about myself, I'm head of the department and the HPC core facility leader in the scope

of NHR, but also at KIT we have a tier three system.

And my department is also responsible for software packages and scientific operations.

But from my point of view, one of our key focus topics is performance optimization as

well as sustainable software development.

And here you can again see the strong point of continuous testing, integration and deployment

as a service so that we are able to set up an infrastructure that every scientist can

use from the very beginning, but also from the other edge of a very experienced user.

If you have a large community coach, for example, that is set up and getting first steps towards

continuous integration, we have the goal to set up and help developers, scientists and

users to get there to develop a continuous integration strategy.

And here on this slide, I've marked three important goals of continuous integration

or continuous X.

The first thing is if you ask yourself, okay, why should I do those kind of things?

Why should I integrate continuous development in my coach or my workflow?
