Thanks for the help!

mbpart should not crash if you compile with serial config.
But you will not be able to use nek moab in parallel with that version of moab, so it makes sense to build parallel moab ________________________________________

Is this the problem? the machine is a cluster and it is configures for multiple users, but let me see.

It is not parallel, indeed
...
 57 Features:
 58 ---------
 59                   Parallel HDF5: no

can you find a parallel hdf5 ?
Can you build one?

on our machines, we use something like this to configure/build hdf5, after downloading the source



#!/bin/bash

export SOURCE=/homes/fathom/3rdparty/hdf5/hdf5-1.8.12
export MPICH=/homes/fathom/3rdparty/mpich/3.1/gnu
export ZLIB=/home/fathom/3rdparty/zlib/1.2.8/gcc
export MYINSTALL=/homes/fathom/3rdparty/hdf5/1.8.12/mpich-3.1/gnu

   $SOURCE/configure --with-zlib=$ZLIB\
     --enable-parallel \
      --prefix=$MYINSTALL \
      CXX=$MPICH/bin/mpicxx \
      F77=$MPICH/bin/mpif77  \
      FC=$MPICH/bin/mpif90 \
     F90=$MPICH/bin/mpif90 \
     CC=$MPICH/bin/mpicc \
      --enable-fortran --enable-fortran2003 --enable-shared   2>&1 | tee configure.log

make  2>&1 | tee make.log &
make install  2>&1 | tee make.install &

No I didn't mbconvert, but the result is the same

Here is the hdf5 settings file, I'd say it is not parallel, but please look.

Thanks,

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)

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.
