When HPC first encountered the GPU they appeared to have very little in common. HPC was all about parallel computing using powerful supercomputers and Linux cluster management to solve complex computational problems, whereas GPUs were computer hardware that found a niche in speeding up gaming graphics. Fast forward to today, where software-defined HPC is becoming an integral part of computing, and the roles of CPUs and GPUs are changing.
ANF Évaluation de performance de codes HPC
Groupe Calcul, en partenariat avec les centres d’excellence HPC européens EoCoE et POP, propose une Action Nationale de Formation dédiée à l’évaluation de performance de codes de calcul HPC du 16-20 septembre 2019 à l’Observatoire de Haute Provence.
Deux parcours :
» Parcours « Base des outils » sur 2 jours ouvert à 25-30 personnes : présentation des outils Scalasca et Paraver (cours + TP).
» Parcours « Diagnostique HPC » sur 3 jours supplémentaires et ouvert à 10 personnes : intégration des outils dans vos codes, productions et analyse des métriques de performance et établissement d’une feuille de route d’optimisation.
Les cours, l’hébergement et les repas sont pris en charge.
Le nombre de places étant limité, vos motivations, votre projet et le code de calcul sur lequel vous souhaitez travailler, sa maturité et son impact sur les communautés scientifiques sont les critères qui seront pris en compte lors de l’évaluation des candidatures.

ISC Conference Keynote: THE ALGORITHMS OF LIFE – SCIENTIFIC COMPUTING FOR SYSTEMS BIOLOGY
Monday, June 17
We are excited to announce Professor Ivo Sbalzarini as the 2019 conference opening keynote speaker. Under the title, The Algorithms of Life – Scientific Computing for Systems Biology, Sbalzarini will discuss how HPC is being used as a tool for scientific investigation and for hypothesis testing, as well as a more fundamental way to think about problems in systems biology. As the Chair of Scientific Computing for Systems Biology on the faculty of computer science of TU Dresden, Sbalzarini is fostering innovative ways to apply scientific computing to the life science domain. He is also the Senior Research Group Leader at the Max Planck Institute of Molecular Cell Biology and Genetics, as well as a member of the Faculty of Mathematics of TU Dresden.
Plan already now to attend all the three ISC keynotes. They are inspiring as well as educational.
Attendee Info & Agenda Planner
After long consideration, we have decided to go paper-free starting this year. Starting 2019, we will be offering all program-related information in our Agenda Planner, and all general information can be found on the Attendee Info page.
We encourage you to actively use these two links to prepare for ISC 2019.

Arrêt de Liger / Outage Liger
Maintenance trimestrielle programmée
Nous vous informons qu’une maintenance trimestrielle programmée (cf. calendrier mesocentre) concernant notre infrastructure aura lieu plutôt le jeudi 21 mars entre 13h30 et 17h30 CEST (au lieu du 12-13 mars de prévu sur le calendrier) profitant le même jour d’une coupure électrique du site récemment programmée par l’Ecole pour des tests d’audit.
En conséquence, la machine LIGER ainsi que ses services associés seront inaccessibles pendant cette période mais les travaux soumis seront préservés. Pour éviter toute nouvelle soumission, tous les noeuds de calcul seront drainés dès 8h00 le matin du 21 mars et exceptionnellement les travaux en file d’attente seront perdus.
Nous vous prions, par avance, de bien vouloir nous excuser de cette perturbation et de la gêne occasionnée.
Scheduled Quarterly Maintenance
We inform you that a scheduled quarterly maintenance (see site calendar) concerning our infrastructure will take place on Thursday, March 21st between 1:30 pm and 5:30 pm CEST where in the same day a general power outage of the site has been recently scheduled for audit tests .
As a result, the LIGER cluster and its related services will be unreacheable during this period but submitted jobs will be preserved. To avoid new submissions, all computing nodes will be drained by 8:00 am CEST on March 21st and all queued jobs will be exceptionally lost.
We apologize in advance for the service disruption and the inconvenience.
