Christmas release! ChASE can now tackle pseudo-Hermitian problem as they arise, for instance in Bethe-Salpeter equation. The solve has been extended by generalizing the Chebyshev filter and designing a new oblique method for the Rayleigh-Ritz projection. [...]

Allocation processes for High Performance Computing (HPC) resources like computing time or storage and data processing resources can contain complex workflows with different roles and user groups involved. We have designed and implemented the Joint Application, Review, and Dispatch Service (JARDS) software for the management of such processes. [...]

<b>Overview</b><br>Version 1.7.0 introduces significant improvements in distributed data handling and numerical linear algebra, including a PyTorch-compatible DistributedSampler, randomized symmetric eigenvalue decomposition, and incremental SVD from HDF5. The release expands interoperability with partial Array API support and PyTorch 2.9.1, adds new distributed operations such as peak-to-peak, and delivers multiple robustness and device-placement bug fixes across MPI, GPU, and I/O workflows.<br>We are grateful to our community of users, students, open-source contributors, the European Space Agency, and the Helmholtz Association for their support and feedback.<br><br><b>Highlights</b><ul><li>DistributedSampler for efficient data loading and shuffling across multiple nodes with PyTorch</li><li>Randomized Symmetric eigenvalue decomposition (eigh)</li><li>Incremental SVD directly from an HDF5 file</li><li>Partial support of the Array API Standard (version: 2020.10), and API namespace under x.__array_namespace__(api_version='2020.10')</li><li>Distributed PTP (peak to peak) function</li></ul>

Choosing the optimal solver for systems of ordinary differential equations (ODEs) is a critical step in dynamical systems simulation. ODE-toolbox is a Python package that assists in solver benchmarking, and recommends solvers on the basis of a set of user-configurable heuristics. [...]

Simulation Environment for Geomorphology, Hydrodynamics and Ecohydrology in Integrated form.<br>First release of the Lagrangian Particle Transport (LPT) module https://gitlab.com/serghei-model/serghei

This is md5deep, a set of cross-platform tools to compute hashes, or message digests, for any number of files while optionally recursively digging through the directory structure. It can also take a list of known hashes and display the filenames of input files whose hashes either do or do not match any of the known hashes. [...]

Cube is a generic set of tools for description and analysis of a multi-dimensional performance space consisting of the dimensions (i) performance metric, (ii) call path, and (iii) system resource. Each dimension can be represented as a tree, where non-leaf nodes of the tree can be collapsed or expanded to achieve the desired level of granularity. [...]
