  15. 17. Mantid in a Browser: a greener alternative to cloud servers?
    Duc Le (STFC)
    04/11/2025, 13:50

    Most major facilities using Mantid run data analysis servers for their users. In many cases these are cloud-based virtual machines (VMs) which are allocated to a single user. The specifications of these VMs are often defined by the most computationally expensive tasks required so in many simpler cases they are underused. Furthermore they are often idle as users are waiting for data or simply...

  17. 16. Unwrapping NAPI
    Scott Boston (Oak Ridge National Laboratory)
    04/11/2025, 15:05

    Most files used for neutron data in Mantid use the NeXus format (.nxs), which specifies a common file structure for neutron, X-ray, and muon scattering data. For many years, Mantid has relied on the NeXus API (NAPI) to handle all elements of reading and writing. However, NAPI development is no longer supported, and the API has not been updated in almost a decade. To move Mantid forward, we...

  22. 46. Beyond Conda: Pixi and the Future of Scientific Python Environment Management
    Chen Zhang (Oak Ridge National Laboratory)
    04/11/2025, 16:25

    Scientific software projects increasingly combine Python with C++, GPU toolkits, and other native dependencies, creating challenges for reproducibility, deployment, and cross-platform support. Traditional tools—Conda, Poetry, uv, Hatch, and PDM—address parts of this problem but leave gaps in speed, determinism, or multi-language integration. Pixi, a new environment manager built on Conda and...
