Your question is quite timely -- we had a long discussion about C++
exceptions just last week at the MPI Forum... :-)
OMPI disables MPI throwing exceptions by default because it can cause
a [slight] performance penalty in some compilers. You can enable it
by adding --enable-cxx-exceptions
Dear OpenMPi developers,
i'm developing parallel C++ application under OpenMPI 1.2.5. At the
moment, i'm using MPI Exception Handlers, but some processors returns
the error below:
"MPI 2 C++ exception throwing is disabled, MPI::mpi_errno has the error code"
Why this, and why only in some nodes
