There are two ways to write parallel netcdf files: Use netcdf-4 (hdf5 based) files Use pnetcdf and old-style netcdf files. Perhaps the best would be to compile netcdf with pnetcdf support only if petsc is configured with exodusii? I can send a patch this afternoon. Greg Sjaardema, the exodus

Does ExodusII write pnetcdf? It's a different interface from (parallel) NetCDF4. Matthew Knepley writes: > Blaise really wants to write in parallel. It would be better to use HDF5, > but evidently > it is broken in ExodusII. Thats what we get for using something from >

Blaise really wants to write in parallel. It would be better to use HDF5, but evidently it is broken in ExodusII. Thats what we get for using something from Sandia. They finally have their revenge. Matt On Tue, Dec 19, 2017 at 5:53 PM, Smith, Barry F. wrote: > > Do you

Do you really need to use pnetcdf? No one uses it and what usefulness does it really provide, best to be avoided. Barry > On Dec 19, 2017, at 1:12 PM, Satish Balay wrote: > > parallel-netcdf-1.9.0.pre1/INSTALL has: > > > 4. Reporting Installation or Usage

[petsc-dev] pnetcdf is a big problem

2017-12-19 Thread Matthew Knepley
The configure is broken, perhaps beyond fixing. I need to give --with-mpi to get anything to work because the way it checks for MPI is screwed up. I will see if I can throw away all its idiotic configure stuff in favor of just telling it everything, but I am not eager to depend on something so
