This note reminded me of something: non-CS end-users think of parallelism in the spatial/geometric sense (typically grids and lattices). --------- | | | | | --------- | | | | | --------- | | | | | --------- Nice and regular. CS-types tend to think of graphs and trees [which have a greater degree of non-determinism]. . / \ /\ /\ I know there is an equivalence between the two, but it is amusing to here these two communities pass each other like ships in the night. Some one else brought up the term "apples and oranges." {Motherhood} Don't forget that both are made of the same basic genetic material (common stuff). I thought about going to the library to burst this analogy by getting chromosome counts. It's all going to depend on how close or far you look at these analyses.
