Supercomputer
Somedays ago I wrote about a chinesse supercomputer, the Tianhe-1A that was proclaimed the most fast on the world for achieve the most hight position of the Top 500 list. Now, an executive, provider of high performance technology, in the supercomputation conference of the 2010, celebrated in New Orleans, give me the reason saying that using together 100.000 smartphones with Android that number can be superated. There are a lot of people that is realizing that the Top 500 doesn't use the best way to measure the performance. Don't left of read the rest of "The list of Top 500 supercomputers is incorrect"
