Ok I'm new to mpi so maybe this is expected behaviour. But when using 
scatter, if number the of threads running is greater than number of 
elements in the array\vector sent to scatter, then there are the 
following issues
        1) if the array contains a user-defined data then an out-of-bounds 
error will occur
        2) otherwise (if is_mpi_datatype is true) the recieved data for threads 
that are "out-of-bound", will contain garbage and as such validity of 
the data cannot be tested.

I assume this not correct behaviour?
