Description
Since HDF5_jll is built with MPI support, NetCDF_jll and the wrapper NCDatasets.jl can use parallel IO.
NetCDF+MPI works well on Linux and MacOS X, however it does not work on Windows.
By looking at the build log files it seems that HDF5_jll (1.14.3) has not detected the MPI libraries on Windows:
Features:
---------
Parallel HDF5: no
Parallel Filtered Dataset Writes: no
Large Parallel I/O: no
Similarily with NetCDF_jll (400.902.211) the parallel support seem to be missing from the Windows NetCDF_jll:
checking whether parallel io is enabled in hdf5... no
checking for library containing H5Dread_chunk... none required
checking for library containing H5Pset_fapl_ros3... none required
checking whether HDF5 allows parallel filters... yes
checking whether szlib was used when building HDF5... yes
checking whether HDF5 library is version 1.10.6 or later... yes
configure: WARNING: Parallel io disabled for netcdf-4 because hdf5 does not support
checking whether parallel I/O is enabled for netcdf-4... no
# Features
--------
Benchmarks: no
NetCDF-2 API: yes
HDF4 Support: no
HDF5 Support: yes
NetCDF-4 API: yes
CDF5 Support: yes
NC-4 Parallel Support: no
PnetCDF Support: no
Do you have any ideas what could be the issue?
