%What if there was a way to avoid having to install a broad range of scientific software from scratch on every HPC
2+
%cluster or cloud instance you use or maintain, without compromising on performance?
3+
4+
Installing scientific software for supercomputers is known to be a tedious and time-consuming task.
5+
The application software stack continues to deepen, especially as the HPC user community becomes more diverse,
6+
computational science expands rapidly, and the diversity of system architectures increases.
7+
Simultaneously, we see a surge in interest in cloud computing for scientific computing. Delivering optimised
8+
software installations and providing access to these installations in a reliable, user-friendly, and reproducible
9+
way is an increasingly highly non-trivial task that affects software developers, HPC user support teams,
10+
and researchers running scientific workloads on HPC systems.
11+
12+
This tutorial aims to address these challenges by introducing the European Environment for Scientific Software Installations
13+
(EESSI, pronounced as \emph{``easy"}), a collaboration between various European HPC sites \& industry partners. The goal of EESSI is to provide
14+
a shared repository of scientific software installations that can be used on a variety of systems, regardless
15+
of which flavor/version of Linux distribution or processor architecture is used, or whether it is a full size HPC
16+
cluster, a virtual machine in the cloud, or a personal workstation.
17+
18+
We cover the basics of EESSI, different use cases for EESSI, how to add software to EESSI, and highlight some more
19+
advanced features. We will also show how to engage with the community and contribute to the project.

We anticipate this EESSI tutorial at ISC to be well attended with 20-50 attendees. This estimate is based on attendance at previous EESSI and EasyBuild events, including:
2+
\begin{itemize}
3+
\item A recent webinar series related to EESSI in May-June 2025 with over 150 registrations;
4+
\item The yearly EasyBuild User Meetings, with over 50 in-person attendees in 2025, alongside over 70 online registrations;
5+
\item An online EESSI tutorial in Dec'23 with over 130 registrations;
6+
\item The in-person (half-day) ISC'22 EasyBuild tutorial with about 20 attendees.
7+
\end{itemize}
8+
9+
%HV: Do we have the attendance of the workshop series we did?
10+
11+
%KH I would've gone with 50/25/25, but this works too (maybe better even)
12+
% MG: This was just a blind guess ;)
13+
%KH seems about right I think, we want to keep it beginner-oriented, 25% advanced may be too much... maybe 50/30/20 is less awkward?
14+
% I love how 'awkward' is such an awkward word to type... :D (no, haven't had beer yet)
15+
16+
% KH: Markus, I'm signing off for tonight... I'll be around tomorrow, definitely in the morning (have a student intern to keep busy in the afternoon, but I'll be around on Slack)
17+
%MG: Yea, I will also stop working soon
18+
19+
% KH: do we need anything from Maxime? It's probably good to tell him that now, since he'll only be around after 1-2pm tomorrow.
20+
%MG: For the submission, we'll need a short bio (some text) For Alan and the two of us, I will copy from last year unless I receive an update.
21+
% KH I already asked him for a bio. And a picture. I'll mail that too. => DONE

%This tutorial is intended for
2+
\begin{itemize}
3+
\item Researchers who want to empower themselves to use a uniform software stack without compromising on
4+
performance; %on top of what is provided centrally by the HPC support team;
5+
\item Developers who build and test their software across different HPC systems and the cloud;
6+
\item System administrators and user support teams, responsible for the operational aspects of HPC systems and concerned about
7+
hardware optimised scientific software installations;
