Dear all,


I use the pre compiled OPAL binary Version 2.4. When I start this binary with "opal" (without mpirun and input file) I get the following messages:


[Debby2:01402] mca_base_component_repository_open: unable to open mca_oob_ud: libosmcomp.so.3: cannot open shared object file: No such file or directory (ignored)

Ippl> CommMPI: Parent process waiting for children ...
Ippl> CommMPI: Initialization complete.

Despite that, the code runs and gives reasonable results, when it is run with an input file. 


But, as soon as I try to use mpirun and the input file that is attached I get the following error:


ErrorError{0}> All Fields in an _expression_ must be aligned.  (Do you have enough guard cells?)

Error{0}> This error occurred while evaluating an _expression_ for an LField with domain {[0:7:1],[0:7:1],[0:0:1]}

Warning{0}> CommMPI: Found extra message from node 1, tag 20015: msg = Message contains 6 items (0 removed).  Contents:

9}> All Fields in an _expression_ must be aligned.  (Do you have enough guard cells?)

Error{9}> This error occurred while evaluating an _expression_ for an LField with domain {[0:7:1],[0:7:1],[7:7:1]}


I tried this on different systems, always with the same result. On another system I got additionally the following errors:


OPAL{0}> Track start at: 10:09:41, t= 0.000 [fs]; zstart at: 0.000 [um]
OPAL{0}> Executing ParallelTTracker, initial dt= 1.000 [ps];

Sorry, if this is confused and a bit much, but I don't know what to do next. Is there a problem in my Input file? Why does OPAL alone these strange errors in the beginning? My system takes roughly two minutes for that file.


Thanks for your input! Cheers
