MPI_TYPE_CONTIGUOUS is the simplest datatype constructor.
It constructs a typemap consisting of the replication of a
datatype into contiguous locations.
The argument newtype is the datatype obtained by concatenating
count copies of
oldtype. Concatenation is defined using extent(oldtype)
as the size of the concatenated copies.
The action of the Contiguous
constructor is represented schematically in Figure 
.

In general, assume that the type map of oldtype is
with extent ex . Then newtype has a type map with count -n entries defined by:
