[MOAB-dev] [Nek5000-users] MOAB partitioning

Hi,
DId you mbconvert again? 
You should be able to use mbpart directly on the original exodus file
Still, you did not compile/configure with mpi. You will not run anything related to moab in parallel. 

Is your hdf5 build with parallel option?
You can look probably at 
/opt/hdf5-1.8.13-gcc/lib/libhdf5.settings 

search for  Parallel HDF5, and for C Compiler 

If parallel, I would use the same mpi implementation

(so configure moab with --with-mpi=, pointing to the same mpi as the one used for hdf5 configuration)

Iulian

Vijay,

I recompiled with hdf5 but still get the same segmentation fault. Here are the log files from configuration/compilation.

Thanks,

You need to compile, HDF5, MOAB and NEK with MPI. Also configure MOAB with NetCDF if you want to convert exodus files to h5m.
