[petsc-dev] Fwd: HDF5: all of that for...

[Barry Smith]

  No, we support HDF5 for vectors because it makes sense; other packages can read them in and do things with them (for example visualization). We don't support HDF5 for matrices cause it doesn't make much sense. Just use the Petsc binary viewers if you want to save PETSc matrices (though even doing that should be rarely needed), HDF5 won't be any faster.
