[FLASH-USERS] Fwd: how to use parallel VisIt on Ubuntu?

[Simon Don]

Thank you very much. In fact my code is now just using PARAMESH amr package
and the HDF5 files is generated by papamesh 's parallel HDF5 I/O. We have
not finished the shift from paramesh to flash.

Now I want to open these hdf5 files by visit. But I can only do this when
the hdf5 file is written by only one processor. When the  MPI is used to
write the hdf5 file, my present visit on ubuntu can not open it rightly.

That the situation and why I am asking parallel visit things.

Regards.
