Hi,

if $mpirank == i

Why the first loop works and the second one does not?
Hmm, this is not MPI-specific. The loop limit "$mpisize" is falling
into a crack between the name of a scalar variable (like your
"mpisize") and an expression to be evaluated (as in, for example,
"1*$mpisize", which would also work). I need to think a little about
the best fix for this.
