> When the software was run on a lone 2.6 GHz CPU, it took around 2 hours to process a typical Jeopardy clue -- not a very practical implementation. But when they parallelized the algorithms across the 2,880-core Watson, they were able to cut the processing time from a couple of hours to between 2 and 6 seconds. That is an impressive amount of parallelism! This is very back of the napkin (and I realise I'm comparing apples and oranges), but a rough estimate for the time taken if the problem was parallelised with 100% efficiency would be: (2 hours) / ((2880 * 3.55) / 2.6) = 1.83098592 seconds
