  • PRTG Catches Network Issues Before They Cause Downtime Icon
    PRTG Catches Network Issues Before They Cause Downtime

    Threshold-based alerts flag problems early, so your team can act before users notice, not after.

    Reactive troubleshooting usually means hearing about a problem from frustrated users, not your monitoring tool. PRTG sets threshold-based alerts across devices, servers and applications, notifying your team by email, SMS or push the moment a metric crosses a set limit. That means catching a failing disk or overloaded server before it becomes an outage and getting time back from firefighting. Start a free trial and set your first alerts today.

    Google DeepMind GraphCast and GenCast

    Google DeepMind GraphCast and GenCast

    Global weather forecasting model using graph neural networks and JAX

    ...The repository provides complete example code for running and training both GraphCast and GenCast, two models introduced in DeepMind’s research papers. GraphCast is designed to perform high-resolution atmospheric simulations using the ERA5 dataset from ECMWF, while GenCast extends the approach with diffusion-based ensemble forecasting for probabilistic weather prediction. Both models are built on JAX and integrate advanced neural architectures capable of learning from multi-scale geophysical data represented on icosahedral meshes. The package includes pretrained model weights, normalization statistics, and demonstration notebooks that allow users to replicate and fine-tune weather forecasting experiments in Colab or on Google Cloud TPUs and GPUs.

    Catalyst.jl

    Catalyst.jl

    Chemical reaction network and systems biology interface

    ...Catalyst defines symbolic ReactionSystems, which can be created programmatically or easily specified using Catalyst's domain-specific language (DSL). Leveraging ModelingToolkit and Symbolics.jl, Catalyst enables large-scale simulations through auto-vectorization and parallelism. Symbolic ReactionSystems can be used to generate ModelingToolkit-based models, allowing the easy simulation and parameter estimation of mass action ODE models, Chemical Langevin SDE models, stochastic chemical kinetics jump process models, and more. Generated models can be used with solvers throughout the broader SciML ecosystem, including higher-level SciML packages (e.g. for sensitivity analysis, parameter estimation, machine learning applications, etc).

    Synchronous Reluctance (machines) - evolution

    ...To perform Finite Element Analysis (FEA) SyR-e is linked to FEMM software, and the simulation process (model creation, pre-processing, post-processing) is automatic and completely controlled from SyR-e code. For the design section, SyR-e embeds automatic procedures based on design equations, minimal FEA simulations or multi-objective optimization algorithm joined with FEA simulations. Once the final design is selected, the SyR-e/FEMM workflow allows the evaluation of several performance figures, but the export to dxf and some leading external motor design software is also possible.

    NAMD-Automator

    A GUI to automate Workflow for setting up and run NAMD simulations

    Welcome to NAMD-Automator, a user-friendly graphical interface designed to simplify the process of Molecular Dynamics (MD) Simulation, by creating configuration files, and automate the simulation with simple form-based tabs. NAMD is one of the widely used software for running these simulations, known for its scalability, speed and efficiency with large molecular systems. However, setting up a typical simulation in NAMD usually requires crafting configuration file for each stage of a Conventional MD Simulation (CMD), such as Minimization, Heating, Equilibration and Production. Following a detailed workflow after creating the files, deciding what should be the content of these files and how to execute the NAMD in command line interface can be challenging for users who are not familiar with scripting or command-line tools. ...
