[Wien] time difference among nodes

[Luis Ogando]

Dear Prof. Marks,

   Many thanks for your help.
   The administrators said that everything is 0K, the software is the
problem (the easy answer) : no zombies, no other jobs in the node, ... !!
   Let me give you more information to see if you can imagine other
possibilities:

1) Intel Xeon Six Core 5680, 3.33GHz

2) Intel(R) Fortran/CC/OpenMPI Intel(R) 64 Compiler XE for applications
running on Intel(R) 64, Version 12.1.1.256 Build 20111011

3) OpenMPI 1.6.5

4) PBS Pro 11.0.2

5) OpenMPI built using  --with-tm  due to prohibited ssh among nodes  (
http://www.open-mpi.org/faq/?category=building#build-rte-tm )

6) Wien2k 14.2

7) The mystery : two weeks ago, everything was working properly !!

   Many thanks again !
   All the best,
                   Luis
