UGA wins an award for the energy efficiency of its data center

14 September 2023

At a ceremony held in Antibes on 4 September 2023, the European Commission's Code of Conduct Datacentres 2023 award was presented to UGA. This year the award recognises six European data centers, including DC-IMAG of UGA.
The Code of Conduct Datacentres was drawn up by the European Commission's Joint Research Centre (JRC). It aims to encourage data center operators and owners to adopt best practices to reduce energy consumption and promote sustainability.
With successive generations of rooms at the Grenoble Data Center, UGA is implementing a policy to reduce its environmental impact. In 2020, two data centers adopted the Code of Conduct Datacentres approach : the DC-IMAG (UGA) and the DC-GREenER (G-INP). Optimising digital hosting goes hand in hand with the creation of a comprehensive range of shared services and everyone’s responsibility in the use of digital technologies.
The UGA Datacentre Technical Committee monitors the performance and use of the Grenoble datacentre for Academic & Research. GRICAD runs it and its members are representative of the organisations hosting equipment. Its ambitious approach to energy efficiency has now been rewarded.
The next generation of data centre is being planned, GR3@, the GReen GRid GRenoble Alpes. Designated a Regional Data Centre by the Ministry, it will host the digital resources needed to meet the challenges of the future, while controlling its environmental impact.

Café Guix - Managing a virtual infrastructure with GUIX

3 July 2023

5 July 2023 from 1pm to 2pm


This final session of the Cafés Guix will be hosted by Yann Dupont, research engineer at GLICID on this link.
Well known as a software package manager particularly well suited to supporting reproducible experiments, Guix's functionality doesn't stop there. We propose to explore some of the "guix system" commands, which can be used to generate complete operating systems and inject interesting features such as consistency and reproducibility. We will start by writing minimal virtual machines, moving on to more complex deployments, and then explore deployments used in production on the GLiCID mesocentre. We will finish with the dessert and try to generate VMs for exotic hardware architectures.

FPGA Seminar

19 June 2023

22 June 2023 at 2pm

Auditorium of the IMAG building

Gricad, MaiMoSiNE et SARI invites you to a seminar on FPGAs, with two presentations
FPGAs and supercomputing: an overview Olivier Richard, LIG laboratory
For several years now, the field of High-Performance Computing (HPC) has been dominated by GPU accelerators. What about Field Programmable Gate Array (FPGA)-based accelerators? Their flexibility, the promise of good energy efficiency, technological developments and the state of programming software all raise questions about the value of usin them in this field. In this presentation, we will discuss these different facets in order to better situate the use of FPGAs in HPC.
A hard look at FPGA usability: from past to present Olivier Muller, TIMA laboratory
FPGAs are very efficient architectures, but they lack programmability, which makes them very difficult for the wider computing community to access. I have been working for nearly 20 years on methodologies to make FPGAs easier to use. This presentation will show, in simplified terms, the difficulties involved in making this 'machine' accessible and shed some light on their current usability.

Café Guix - Package transformations for demanding HPC users

17 May 2023

30 May 2023 from 1pm to 2pm


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

27 avril 2023

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

27 February 2023

6 March 2023 from 1pm to 2pm


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?
You will find all the information concerning the "Cafés Guix" here.

Café Guix : When packing becomes complicated

31 January 2023

21 February 2023 at 1 pm


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.

Information on repeated power outages

27 july 2022

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.

14 october 2021

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.

CNRS Cristal

This year, the CNRS has decided to reward the work of the PLMteam with a crystal. The PLM (Platform in Line for Mathematics) is a national infrastructure distributed in mathematics laboratories, managed within the framework of the RT Mathrice of the CNRS, by a technical team distributed geographically.
Its partnership with GRICAD, under the aegis of INSMI, will enable PLM to take the turn of cloud computing.
Congratulations to Laurent Azema who joins the GRICAD system team and will lead the Datacentre Technical Committee, in the same spirit of cooperation of its members towards a common achievement in the service of the research.

Evolution of infrastructures for AI and computing on GPU

In recent months, demand from GPU computing research communities, especially AI, has grown significantly. To meet this growing need, GRICAD added 4 new GPU compute nodes in the DAHU cluster. GRICAD, through this cluster, provides Grenoble research staff and their collaborators with 6 GPU nodes, ie a total of 24 NIVIDA Tesla V100 GPUs (32GB of RAM per GPU). It should be noted that these nodes are very similar to the GPU / IA nodes that the supercomputer of the IDRIS (national computing center CNRS) Jean Zay.
We have also made it possible, in our cloud computing service called NOVA, the deployment of virtual machines ( VM) on demand including GPUs. If you do not have strong performance needs but are in a testing / code development / prototyping phase, do not hesitate to orient yourself towards this service, which is more flexible, flexible and versatile.

As a reminder, MANTIS (V1 or V2) is an iRODS distributed storage cloud available from all the compute nodes of the GRICAD HPC infrastructure. It is an efficient way to store the input data or the outputs of the simulations carried out on the various calculation servers of GRICAD. It is powerful (because storage is spread across multiple nodes), capacitive, and expandable (labs can easily help expand storage capacity by adding new 250TB nodes), and provides a programmable rules engine.
With an expandable overall volume of 750TB, each user is allocated one terabyte of space to store their data. To request an extension of this space, do not hesitate to contact us at

Grille de stockage haute capacité MANTIS-2

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.

Support for the Alcov2 project

GRICAD participated in the implementation of the Alcov2 survey for the study of the transmission of the new coronavirus in French households conducted by a Parisian research team.
This survey is aimed at all households French having possibly experienced, even without certainty, the presence of the new coronavirus during the containment period. It will make it possible to better understand the modes of transmission in households but also in transportation, schools, places of work, gathering places, etc.
