ARCS 2025: Mastering novel HPC chip architectures

The ARCS conferences series has over 37 years of tradition reporting
leading edge research in computer architecture and operating systems.

New chips for high-performance computing (HPC) are being developed in and outside Europe
(e.g. ARM processors for HPC, RISC-V chips, special purpose ASIC designs, etc.) and even
disruptive technologies such as QPU accelerators are being connected to HPC systems.
New chips are designed either as general purpose devices with a wide user portfolio in mind,
or target the needs of specific applications (e.g. machine learning pipelines or deep learning
workloads, mobile or embedded systems). Accordingly, they might rely on well established
architectural approaches (CPU-like, vector-extensions), or bring completely new disruptive
ideas, always with the aim of limiting energy consumption. When these are integrated in HPC systems,
the overall system design becomes more and more heterogeneous.

These increasingly complex architectures require optimizations in application code to
exploit the full performance potential. There are standard optimization strategies
that can be implemented specifically for certain architectures, and there may also
be optimization rules that are totally specific to an accelerator or a hybrid
processor-accelerator architecture. Porting HPC code to new architectures is
an important challenge: it is desirable to achieve performance without having
to redesign the whole code, or at least to be able to follow standard optimization rules.

The ARCS’25 conference welcomes all contributions on hardware architectures, as well as
their programming models, software stacks (operating systems, compilers…), their insertion
into computing systems, and the challenges to port optimized code.

In addition to the main conference, ARCS will host:
-A special track on Organic Computing.
-A special track on Dependability and Fault Tolerance.
-A PhD forum to present the work of young doctoral students (10 page papers).
-A Group forum for new professors, individual researchers, and consortia to present their research group’s project (5 page papers).

The proceedings of ARCS 2025 will be published in the Springer Lecture Notes on Computer Science
(LNCS) series. A best paper will be elected by the Program Committee, and
a publicum’s favourite presentation award will be chosen by the audience.
Both awards will be given at the conference.
