October 11 to 15, 2021


The meeting is composed of four workshops and a plenary session: detailed program.


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.

Mantis 2

GRICAD's new distributed storage infrastructure, MANTIS V2 is now available to all users of GRICAD computing machines. It replaces the MANTIS infrastructure which, after more than 10 years of good and loyal service, had become obsolete.
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.
