WebNov 3, 2024 · The locking mechanism used by hdf5 on Windows is available only when running in a DLL which is not the case for Node.js addons. The GDAL NetCDF driver implements its own locking so it is not affected. When using raw HDF5 files on Windows... WebFor further information on thread-safe HDF5, see the Thread-safe page and the documents referenced on that page. The HDF Group has a design plan for a more efficient implementation of thread-safety, but currently does not have the resources to implement the plan.
