abstract = {In a longstanding tradition, the John von Neumann Institute
for Computing (NIC) holds biennial symposia, accompanied by
proceedings volumes – illustrating the broad range of
modern computational science and the advances in high
performance and data-intensive computing. Symposium and
proceedings thus provide a glimpse into supercomputingbased
research at its best and make it accessible both to the
general public and to computational scientists across
disciplinary boundaries. As such they foster exchange
between different fields of natural science and engineering
with respect to modern algorithms and computational
strategies. To this end, on March 6th and 7th, 2025,
computational scientists will again convene in Jülich for
the 12th NIC symposium. We are very pleased that this time
it is again possible to showcase the breadth of
high-performance computing research supported by the NIC
with contributions from astrophysics, elementary particle
physics, and statistical physics of hard and soft condensed
matter, computational chemistry and materials science, as
well as computer science, fluid mechanics, and earth system
modelling – covering both fundamental research and
projects with a strong application orientation. We are also
delighted to extend a very warm welcome to our colleagues
from the Goethe University Frankfurt who have joined the NIC
in 2024 as a new member institution. Together, we will
further strengthen research in the field of computational
science in Germany and Europe. The NIC continuously provides
the scientific community with essential high-performance
computing resources and training. Within the framework of
the Gauss Centre for Supercomputing (GCS), the Jülich
Supercomputing Centre (JSC) has been operating the modular
supercomputer JUWELS (Jülich Wizard for European Leadership
Science) since 2020, which is composed of a CPU-based
cluster and a GPU-based booster module. Thanks to the
excellent training and user support by the technical experts
from the JSC, the JUWELS architecture has been widely
adopted across disciplines and communities. In particular,
porting codes to the booster module and adapting algorithms
to the GPU architecture has been fundamental in getting the
disciplines ready for the next generation of GPU-based
exascale computing. After the decision by the European High
Performance Computing Joint Undertaking (EuroHPC JU) that
the Forschungszentrum Jülich is to operate the first
exascale supercomputer in Europe, the JSC and the GCS have
been preparing for JUPITER (Joint Undertaking Pioneer for
Innovative and Transformative Exascale Research). The new
system will become available in 2025. To optimally prepare
applications and users for JUPITER and to facilitate the
transition from current petascale and pre-exascale
supercomputers to actual exascale computing, the JSC has
launched JUREAP, the JUPITER Research and Early Access
Program. In the first phase of 2024, users have participated
in the Scalability and Performance Evaluation Phase (SPEP),
an open call to test and demonstrate the performance and the
scaling of the applications on test architectures. In
September 2024, the GCS Exascale Pioneer Call has been
initiated with two objectives: the successful projects are
given early access to JUPITER during build-up, approximately
from January 2025 onwards, and the call distributes JUPITER
resources for the time period after the machine is
officially operational until the end of October 2025 –
thus enabling groundbreaking computational research for the
German scientific community. A more detailed overview on
JUPITER, the new opportunities that exascale computing opens
up to all scientific communities, and in particular the
shifts driven by the wave of developments in AI technologies
and large foundation models are provided in the introductory
article of the proceedings by Thomas Lippert and coauthors
"Paradigm Change or Riding the Wave? Exascale-Computers to
Train Foundation Models”.},
