[Trilinos-Users] R: HDF5 - segmentation fault

I'm using Trilinos 11.0.3, Hdf5 1.8.9
All the HDF5 tests of trillinos have been passed, all the examples work fine.
The code I've mailed work with 1,2,3 cores but fails with 4 cores.

hi Andrea,
i tested your example and it is working for me, so the problem is in
the configuration/installation of your trilinos and hdf5 libraries.
you can try turning on epetraext examples and tests to see if they are working.
i used trilinos 10.12.2 and hdf5 1.8.9.
ciao

antonio
