Derived Datatypes<br />
› A derived datatype is a sequence <strong>of</strong> primitive<br />
datatypes and displacements<br />
› Derived datatypes are created by building on<br />
primitive datatypes<br />
› A derived datatype’s typemap is the sequence <strong>of</strong><br />
(primitive type, disp) pairs that defines the derived<br />
datatype<br />
› These displacements need not be positive, unique, or<br />
increasing.<br />
› A datatype’s type signature is just the sequence <strong>of</strong><br />
primitive datatypes<br />
› A messages type signature is the type signature <strong>of</strong><br />
the datatype being sent, repeated count times<br />
