<div style="direction: ltr;font-family: Tahoma;color: #000000;font-size: 10pt;">Dear all,<br>
I am trying to have some DFT+U calculations on a system with Tb including f electrons.<br>
I've never done any Hubbard calc so I was increasing slowly the U parameters.<br>
The calcs goes well up to .8 but when I increase it simply crash after XX cycles with a nasty mpi error:<br>

Rank 21 [Thu Jul 16 15:51:04 2015] [c4-2c0s15n2] Fatal error in PMPI_Bcast: Message truncated, error stack:<br>
PMPI_Bcast(1615)..................: MPI_Bcast(buf=0x75265e0, count=160, MPI_DOUBLE_PRECISION, root=0, comm=0xc4000000) failed<br>
MPIR_Bcast_impl(1455).............: <br>
MPIR_CRAY_Bcast(420)..............: <br>
MPIR_CRAY_Bcast_Tree(152).........: <br>
<br>
Being completely fresh in DFT+U I was wondering if it could have been a reason, if it is a "well known" problem of the implementation in QE or if it can be fixed somehow.<br>
<br>
Many thanks for helping<br>
