However, when I run the thing sequentially with the same (high, but not
that high, actually) number of replications, there is no problem.
Therefore I believe it must be something more MPI-specific.
Sven, why don't you send us (some of us, offlist if you wish) all
that's needed to produce the problem (if only sometimes)?
There are tools we can use to investigate this, valgrind in
particular.
