3. Our Solution
As we have attempted to describe here in simple tabular form,
our solution to the stated problem has been to develop a heterogeneous
computing environment (HCE) through which our two primary
computational tasks (CFD simulation and visualization)
are performed simultaneously on two separate computing
platforms, each of which has been configured
to handle the assigned task in an optimum fashion. Communication
between the tasks (the link) is accomplished over existing local area networks.
