font-family:Arial'>I´m dealing with some error event in MPI, using a c++
implementation.<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>In particular I would like to signal a sort of “error
event” across the whole MPI cluster. <br>
For the moment, the only way I´ve found to report this emergency station is to
call an MPI Abort function, but this is of course too rude for my purpose, as
the whole mpi cluster is aborted without any additional control from the
programmer side.<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>What I would like to do is to intercept a MPI error. This
happens, just suppose, on one executable (say node 0). Than Node 0 catches it
with an exception mechanism (and this is quite easy, just setting
MPI_ERRORS_THROW_EXCEPTION standard handler, or setting an appropriate other one).
And then Node 0 communicate the error also to the other executables and
machines belonging to the cluster, so that they also reach the same emergency situation,
possibly throwing the same MPI::Exception ..<o:p></o:p></span></font></p>
