Subject: Structural Dynamical Systems: Computational Aspects, Italy, Jun 2024

SDS2024 is the 12th edition of a series of meetings whose aim is to
bring together researchers from different fields, mainly Mathematics
and Engineering, and give them the opportunity to discuss, in a
friendly atmosphere, recent developments in computational and
theoretical methods for Dynamical Systems and PDEs, and their
applications. This year's edition will host four minicourses on
special topics and a session of short talks.

The meeting will be held at the Corvino Resort in Monopoli (BA),
Italy, from June 11 to June 14, 2024.

Titles and organizers of the four minicourses are listed below.

From finite elements to virtual elements and applications.

engineers, and practitioners for the purpose of sharing their
experiences in the development of new algorithms, applications,
architectures for parallel and distributed computing, as well as
modeling and simulation, visualisation, and data analytics.

We cordially invite you to submit your contribution to the 23rd ISPDC
conference, considering our mission to bring together researchers,
engineers, and practitioners involved in the development of new
algorithms and architectures for parallel and distributed computing,
as well as visualisation and post-processing. We consider the
following area of interests, but not limited to: Applications of
parallel and distributed systems; Efficient Support for the Computing
Continuum (combining HPC, Cloud and Edge Computing); Algorithms and
Models for Large Scale Applications; Architectures and Environments
for Parallel and Distributed Computing; Performance Modeling, Analysis
and Evaluation for Parallel and Distributed Systems; Security and

Subject: Postdoc Position, German Aerospace Center, Germany

A PostDoc position (24 months) is open in the group of Predictive
Simulation Software in the Institute of Software Technology,
Department of High Performance Computing.

The group of Predictive Simulation Software develops a comprehensive
software package that simulates the spread of infectious diseases. In
addition to high-resolution modeling of the spread of infection, the
effect of countermeasures is considered and included in scenario
considerations. The modeling and simulations are done by complementary
and supplementary (multi-level) models.

We are searching for a PostDoc in Mathematics, Computer Science or
comparable with good skills in C++ to further develop our software.
