RESEARCH ENGINEER - PINNS FOR PRESSURE WAVE PROPAGATION IN HETEROGENEOUS MEDIA (RE1)

Barcelona - Barcelona

Descripción de la oferta de empleo

About BSC The Barcelona Supercomputing Center - Centro Nacional de Supercomputación (BSC-CNS) is the leading supercomputing center in Spain.
It houses MareNostrum, one of the most powerful supercomputers in Europe, was a founding and hosting member of the former European HPC infrastructure PRACE (Partnership for Advanced Computing in Europe), and is now hosting entity for EuroHPC JU, the Joint Undertaking that leads large-scale investments and HPC provision in Europe.
The mission of BSC is to research, develop and manage information technologies in order to facilitate scientific progress.
BSC combines HPC service provision and R&D into both computer and computational science (life, earth and engineering sciences) under one roof, and currently has over staff from 60 countries.
Look at the BSC experience.
BSC-CNS YouTube Channel Let's stay connected with BSC Folks! We are particularly interested for this role in the strengths and lived experiences of women and underrepresented groups to help us avoid perpetuating biases and oversights in science and IT research.
In instances of equal merit, the incorporation of the under-represented sex will be favoured.
We promote Equity, Diversity and Inclusion, fostering an environment where each and every one of us is appreciated for who we are, regardless of our differences.
If you consider that you do not meet all the requirements, we encourage you to continue applying for the job offer.
We value diversity of experiences and skills, and you could bring unique perspectives to our team.
Context And Mission The intern will focus on how to reduce the computational cost of physics-based simulation of acoustic wave in various propagation media, by means of Physics-Informed Neural Networks (PINNs).
Neural networks are seen as universal function simulators capable f approximating the PDF's solution function.
In this work the NNs will be designed and trained to take in account physical laws, boundary conditions as well as propagation medium heterogeneity.
Key Duties Acquire expertise in several concepts.
- the wave equation and the impulsive response of an isotropic elastic medium (Helmholtz equation for acoustic wave propagation in 2D) in the presence of a point source.
- its solution and Python implementation using finite differences, in order to be able to generate training data for machine learning purposes.
Contribute to.
- implement the physics-based Helmholtz equation's solution using finite differences - implement an FFNNs using available Python libraries and framework, e.
., TensorFlow, to solve the corresponding PDEs - distribute and/or parallelize the training of the FFNN, using BSC’s supercomputing infrastructure, namely either the ACC of GPP partitions of Marenostrum 5 (MN5) for homogeneous propagation media, specifying boundary conditions (BCs) implicitly in the training data and plotting result and errors specifically with regard to BCs.
Parametrize the propagation media and include the possibility of smoothly varying material properties in both the physics based finite difference code, as well as in the FFNN (PINN).
Prepare a situation and final report to be delivered on the last day of the student's interneship.
The report should include (i) a structured bibliography on salient questions relevant to the technical work to carry out, (ii) a description of methodologies used throughout the interneship, (iii) any developped code, and (iv) results.
Code developped during the interneship will be stored in the https://gitlab.
sc.
s/wavephenomenagroup/ version control repository.
Requirements Education Course subjects' concentration in computational mathematics and data analysis.
Essential Knowledge and Professional Experience Relevant scientific project experience gained through recent academic courses are positively valued in the following areas.
complex data analysis, machine learning, deep learning, high performance computing, distributed computing paradigms (e.
.
OpenMP, OpenACC, MPI) Additional Knowledge and Professional Experience Fluent written and spoken English Collaborative and version controlled work environments (e.
.
gitlab, github, etc.) Unix/Linux and any related scripting shell Python 3, C/C++ Differential calculus Basic solution of the Helmholtz equation and qualitative concepts pertaining to wave propagation, useful in describing the dynamic behavior of waves, including phenomena such as wave dispersion, wave interference, and the generation of harmonics.
Competences Good communication and presentation skills.
Ability to work both independently and within a team.
Conditions The position will be located at BSC within the CASE Department We offer a full-time contract (37.
h/week), a good working environment, a highly stimulating environment with state-of-the-art infrastructure, flexible working hours, extensive training plan, restaurant tickets, private health insurance, support to the relocation procedures Duration.
Open-ended contract due to technical and scientific activities linked to the project and budget duration Holidays.
23 paid vacation days plus 24th and 31st of December per our collective agreement Salary.
we offer a competitive salary commensurate with the qualifications and experience of the candidate and according to the cost of living in Barcelona Starting date.
Applications procedure and process All applications must be made through BSC website and contain.
