The concept of HCS MOST (Heterogeneous Computing Systems with Machines of the Same Type) has been proposed recently by us.HCS MOST is classified into three classes and the general speedup formulas for them have been introduced.In this paper
with a different application task model
a new speedup model for the second class of them
i.e. HCS〈0
m *
0〉system
is presented.The calculation results derived from computation tasks with different parallelism distribution for an example system HCS〈0
