Active discussion at the NVIDIA IT4I event (Ostrava)

In the context of the Marie Curie ATLANTIC project, I could benefit from 2 days training in CUDA and OpenACC. This knowledge is today essential for harvesting the power of high power computers nowadays. Pictures of the event are available here.

It seems the news may be also available in Optics and Photonics News of January 2020.

Invited talk in ALT conference, invited HiLASE seminars and HPC project

  • Participants of the Marie Curie project “ATLANTIC” (work packages 3 and 5) stayed one month at HiLASE in September. Assoc. prof. Usman Sapaev and Dr. Sergey Starinskiy both performed an invited HiLASE seminar and presented invited oral presentation at the conference ALT19 (Advanced Laser Technologies).
  • The computational time offered by PRACE (HPC project DECI15th “BOLERO”) is now accessible. Certifications by FZU are sufficient to access the resources.
  • T. Derrien presented an invited talk at the ALT19 conference on the long standing works on transient excitation of electrons in solids.

BOLERO HPC (PRACE) project: accepted.

The BOLERO PRACE project for high power computation (HPC) has been accepted. Therefore, we got 2.6 million core-hours on top of our resources for 2019-2020.

This will support the heavy computations we run using time-dependent density functional theory at HiLASE RP4 for making predictions in the field of laser processing, and for the ATLANTIC project.

Seminar at the Tokyo University, June 19th 2019

On June 19th, TJY Derrien was honored to present a seminar in the group of Prof. Ishikawa (University of Tokyo).
Title was: “Predictive modeling of materials excitation, melting and nanostructuring upon femtosecond laser irradiation: first-principle and phenomenological perspectives”.
Duration of the talk was 1h. Here is the link to the official announcement.

Questions from the inviting professors were accurate and numerous.

HPC: We have been allocated 3.5 million core-hours by Czech Republic

The project IT4I/MORILLE has been granted. It consists in providing a computational time of 3.5 M core-hours to implement the Marie Curie ATLANTIC project we obtained with HiLASE and with a number of partners. The PI is Dr T. J.-Y. Derrien, and the project includes the training of several people at HiLASE, plus the hosting of the incoming researchers of the ATLANTIC project.

Thanks to this project, HiLASE has now access to all the scales of machines that are necessary to prepare efficient HPC simulation codes.

  • BIATRI-SRV to prepare codes for shared memory architectures (OpenMP).
  • MetaCentrum to prepare codes for distributed memory architectures (MPI) and GPU simulation.
  • IT4I to execute codes on distributed memory architectures and GPUs.

Our new paper on surface polaritons inducing LIPSS in thin films has been published online

Our paper titled “LIPSS on thin metallic films: New insights from multiplicity of laser-excited electromagnetic modes and efficiency of metal oxidation” has been published in Applied Surface Science (IF 4.4).

The paper explains the period of Laser-Induced Periodic Surface Structures (LIPSS) on thin Cr film, with accounting for the influence of the substrate. It also provides a convincing model of HSFL formation where the role of metal oxidation is dominant.

  • “This is a novel idea, taking a brave step forward compared to existing works”
  • “The outlined scientific approach is described in a very detailed manner, and the PI is competent to what he is proposing.”

Short answers to specific points

  • To what extent has the PI demonstrated the ability to conduct ground-breaking research? Very good | Very good | Very good
  • To what extent does the PI provide evidence of creative independent thinking? Very good | Very good | Very good
  • To what extent does the PI have the required scientific expertise and capacity to successfully execute the project? Very good | Excellent | Very good

Optional comments

  • “The PI has a very good publication record and he has set a very challenging goal for himself in this project.”
  • “A very satisfactory scientific and research track record with many publications, excellent collaborations, funding and research experience.”

Final mark

  • B (is of high quality but not sufficient to pass to Step 2 of the evaluation.)
