Passage A Recent studies have shown that sophisticated computer models of the oceans and atmosphere are capable of simulating large-scale climate trends with remarkable accuracy.
Main Point (Passage A)
The continuing increase in computing capacity of the average desktop computer means that climate simulations can now be run on privately owned desktop machines connected to one another via the Internet (Third Paragraph of Passage A).
Passage Map (Passage A)
P1 - The use of computer models to predict large-scale climate trends. P2 - The computations are so intense that individual computers are inadequate. P3 - Individual computers can be linked together via the Internet to run simultaneous calculations and conduct complex modeling when the public’s interest has been captured.
Main Point (Passage B)
We are now living through a great paradigm shift in the field of computing, a shift from sequential computing to massive parallel computing (Third Paragraph of Passage B).
Passage Map (Passage B)
P1 - Many problems are naturally parallel. P2 - An example—ants. P3 - Since many problems are naturally parallel, it makes sense to use parallel computing to solve them.
