Café Guix - Package transformations for demanding HPC users

30 May 2023 from 1pm to 2pm

Visio

This session will be moderated by Ludovic Courtès, research engineer at the Inria centre at the University of Bordeaux, on this link.
People who work in HPC are known to be demanding when it comes to flexibility in how software is built: they want to be able to combine selected versions, enable or disable certain build options, add or not certain optional dependencies, etc. Spack is known for meeting these needs from the command line.
In this spirit, but in a framework where reproducibility and traceability are the default, Guix's package transformation options allow you to adjust software to your needs from the command line. We will see the main transformations, from changing dependencies with `--with-input` to optimising for a micro-architecture with `--tune`, to choosing specific revisions with `--with-commit`.
And of course, it will be an opportunity to answer your questions on the subject! You will find all the information concerning the "Cafés Guix" here.

A mission in partnership with GRICAD to strengthen the capacities of the National Computing Centre of Côte d'Ivoire

An expert mission from the National Computing Centre of Côte d'Ivoire (CNCCI) was led by Bruno BZEZNIK, research engineer at GRICAD and Mondher CHEKKI, research engineer at the Institute of Environmental Geosciences (IGE). This mission, financed by the Institut de Recherche pour le Développement (IRD), meets the ambition of the Ivorian government to develop an ambitious programme allowing major advances in various scientific and industrial fields.
The CNCCI, with a computing power of 322.56 TFlops (322.56 thousand billion elementary calculations in one second) on 7200 cores, 300 nodes and a storage capacity of 1.6 Po, represents the first high-performance computing structure in West Africa. After three days of expertise, Bruno BZEZNIK and Mondher CHEKKI were received on 29 March 2023 by the Minister of Higher Education and Scientific Research, Professor Adama DIAWARA. This mission allowed them to transmit a report drawing up a state of the art of the centre as well as a list of recommendations.
A partnership between GRICAD and the CNCCI could be set up in the coming months to support scientific, pedagogical and technical collaborations.

Café Guix - Guix and the long term: challenges and countermeasures

6 March 2023 from 1pm to 2pm

Visio

This session will be moderated by Simon Tournier, research engineer at the Université Paris Cité and Inserm at the Institut Saint Louis, on this link.
In a context of reproducible research, one of the challenges is the ability to «capture the computational environment» for redeployment or inspection. And so there is an underlying dimension: the passage of time. Servers are no longer reachable, sources are no longer available, etc.
In this Café Guix, we will present the problem, the archiving solution Software Heritage and how Guix is positioned.
Our aim is to introduce the question of «how to do again later and there what has been done today and here ?» and to initiate a discussion around another corollary question: how to quote a software?

Café Guix : When packing becomes complicated

21 February 2023 at 1 pm

Visio

This session will be hosted by Ludovic Courtès on this link.
To give an idea of what a package is, we usually start by showing a [simple case], that is immediately understandable and reassuring. In reality, it is not uncommon for things to get complicated.
In this session, we will see how to adapt a package definition to specify configuration options or build flags, change [build phases], manipulate source or installed files, reference package dependencies.
We will find again some of the notions discussed in the introduction to the language Scheme of the session of November 29, 2022, for your greatest pleasure. Bonus: you are welcome to bring your own packaging concerns to discuss them!
At the end of this session, 15 minutes will be devoted to your various questions including on topics other than the one presented in this café.
You will find all the information concerning the "Cafés Guix" here.

How to concretely disseminate your data in the UGA collection of Research Data Gouv?

29 november 2022 from 1 to 2 pm

Videoconference

Inaugurated by the Ministry of Higher Education and Research last July, the Recherche.Data.Gouv.fr platform allows users to search or deposit data sets on a trusted national repository. The challenge is to widely disseminate research results to promote open science and collaboration. This is one of the objectives of the National Open Science Plan.
This system is part of an ecosystem that promotes the sharing and opening of research data and offers different types of support to researchers. In this context, the UGA, which is very involved in Research Data Gouv, has an institutional space accessible to all members of the Grenoble Alpes community by simple authentication.
To open science, participate and deposit your data!
La cellule data Grenoble Alpes is at your disposal to support you in the management of your data. Do not hesitate to contact her at sos-data [at] univ-grenoble-alpes.fr. To inform you about all these topics and show you how to concretely disseminate your data in the UGA collection of Research Data Gouv, she offers a webinar here.

In the perspective of future European exaflopic machines, this report, resulting from the reflections of sub-project 3 (SP3) of the exascale France project, presents a vision of the current state of the applications and the dimensioning of the technical and human needs relative to these applications which will enable them to run on these machines.

Information on repeated power outages

Dear users, as you may have noticed, these last weeks (July 15 and 20, 2022) we experienced some power outages which forced us to stop the computing servers. Once again, we apologise for this.
These power outages are caused by the electricity provider ENEDIS, their explanation is as follows:
The incidents of July 15 and 20 were due to faults on underground HV cables. This period of heat wave puts a lot of stress on the distribution network, especially the underground power lines which are sensitive to high temperatures. The repair of these 2 cables has been done and we are now back to normal power supply.

The Recherche Data Gouv ecosystem and the Data Grenoble Alpes Unit

On Friday, July 8, 2022, the Minister of Higher Education and Research inaugurated Recherche Data Gouv, an ecosystem for sharing and opening research data.
Recherche Data Gouv includes on the one hand a repository and a registry for deposit, publish and disseminate data, and on the other hand data management clusters, thematic reference centers and ressources centers to support research teams around data.
The UGA, through GRICAD and BAPSO, actively participates in the Recherche Data Gouv repository module.

GRICAD is very involved in Research Data Gouv, in particular through the strong presence of GRICAD staff in the Cellule Data Grenoble Alpes which is one of the first 5 data management clusters labeled by the Ministry in June 2022. 2 sites to consult to know everything about :

• Recherche Data Gouv
  
• Open Science at UGA

Silenus

Silenus, Gricad's new scratch storage infrastructure for HPC , is now operational.
This infrastructure was acquired and implemented to meet the needs of very high performance scratch storage, especially on very intensive reading/writing operations. It is accessible from the Dahu cluster as a local storage system, like Bettik, under the /silenus tree. There is a /silenus/PROJECTS/ folder for each Perseus project. In each of these folders there is a folder common to all the members of the project as well as a folder for each member of the project. These folders automatically have the right rights in reading and writing to allow you to share your data with your collaborators within the same project and to keep your personal data confidential. Folders /silenus/chunks_* offer possibilities for optimizing the use of the platform in specific contexts. Silenus is a real scratch space on which data is automatically deleted after thirty days of inactivity. You will receive a warning message for each file that reaches or exceeds 20 days but it is strongly recommended to use Silenus only during the execution of the job with a copy of the data on this space just before or at the beginning of the job and a transfer to another more perennial storage space at the end or directly after the job.

Grille de stockage haute capacité MANTIS-2

MANTIS is a storage platform initially intended for inputs / outputs of "grid" type calculations, which are capable of bring into play the CPU resources of all the computing machines managed or co-managed by Gricad. It offers a large storage capacity accessible directly from any computation node and allows the storage of transient data or that must be accessed from heterogeneous sources. This scalable distributed platform driven by "iRods" middleware has been running since 2011 and had reached the size of 1.2 petabytes spread over about fifteen servers. Today, GRICAD has just put MANTIS-2 into production, a second similar platform, also managed under iRods and intended for replace the first grind shortly. It already offers 750 terabytes delivered by only 3 servers. Its capacity and performance are therefore highly scalable, by simply adding 250 base bricks terabytes. In addition, it benefits from better synchronization at Gricad authentication system (Perseus), removing the problematic dissociation of connection keys. Users will soon be invited to migrate their data from MANTIS to MANTIS-2.

Involvement in the fight against Covid-19

GRICAD, thanks to its "Nova" cloud, supports several projects around the Covid-19, in particular data collection and analysis, as well as MODCOV19 coordination:

• the projet EX-COVID-19, carried by Laboratoire Impact de l'activité physique sur la santé (IAPS)
