This starts by considering the analytic form for communication overhead and illustrates its stencil dependence in simple local cases -- stressing relevance of grain size
|
The implication for scaling and generalizing from Laplace example is covered
-
We covered scaled speedup (fixed grain size) as well as fixed problem size
|
|
We noted some useful material was missing and this was continued in next lecture (Sept 10,96)
|
|
The lecture starts coverage of computer architecture covering base technologies with both CMOS covered in an earlier lecture contrasted to Quantum and Superconducting technology
