Version 0.1.0 - November 2025<ul><li>Implementation of sequential RGF for block tridiagonal systems. This can use threading only via BLAS calls.</li><li>Implementation of a parallel version of RGF, also for block tridiagonal systems, that can use Julia threads [...]

The instrumentation and measurement framework Score-P, together with analysis tools build on top of its output formats, provides insight into massively parallel HPC applications, their communication, synchronization, I/O, and scaling behavior to pinpoint performance bottlenecks and their causes.<br>Score-P is a highly scalable and easy-to-use tool suite for profiling (summarizing program execution) and event tracing (capturing events in chronological order) of HPC applications.<br>The scorep instrumentation command adds instrumentation hooks into a user's application by either prepending or replacing the compile and link commands. C, C++, Fortran, and Python codes as well as contemporary HPC programming models (MPI, threading, GPUs, I/O) are supported.<br>When running an instrumented application, measurement event data is provided by the instrumentation hooks to the measurement core [...]

Heat 1.6.0 Release Notes<br><br><b>Overview</b><br>With Heat 1.6.0 we release the next major set of features, including continued developments within the ESAPCA project funded by the European Space Agency (ESA).<br>The main focus of this release is a significant expansion of our <b>distributed linear algebra</b> capabilities, including full SVD, symmetric eigenvalue decomposition, and polar decomposition, all leveraging the efficient "Zolotarev approach". We also introduce Dynamic Mode Decomposition (DMD and DMDc) for the analysis of complex systems.<br>On the performance side, the <b>MPI communication layer</b> has been enhanced to support buffer sizes exceeding the previous $2^{31}-1$ element limit, enabling data transfers at an unprecedented scale.<br>This release also introduces support for the <b>Zarr data format</b> for I/O operations and experimental hardware <b>acceleration on Apple Silicon</b> via Metal Performance Shaders (MPS).

Preprocessing routine for ground-based atmospheric monitoring network data. Utilizing a k-means soft constrained clustering algorithm to derive a representative sub-sampling of the availiable data into an assimilation and validation set.  This work was partially performed as part of the Helmholtz School for Data Science in Life, Earth and Energy (HDS-LEE) and received funding from the Helmholtz Association of German Research Centres..

The pySDC project is a Python implementation of the spectral deferred correction (SDC) approach and its flavors, esp. the multilevel extension MLSDC and PFASST. [...]

This software contains the EURAD-IM source code (version 5.11.1) used for the CAMS regional air quality service from November 2023 to November 2024. The model is described and evaluated in 'Copernicus Atmosphere Monitoring Service - Regional Air Quality Production System v1.0' submitted to Geoscientific Model Development..
