Hello, The graphic card company NVIDIA just announced recently an incredible machine : The NVIDIA Tesla Personal Supercomputer. price ; 9995$ US or 7000 Euros. computing power ; 4 teraflops. I don't know if you realize this, it means that a relatively fortunate but still ordinary citizen can buy a machine which is big as an ordinary pc and which represent the computing power of the TOP500 computer list of 2001. In other words, if we were in 2001, that 'home' computer would be 2nd in the world! This is purely incredible. Well, here is the second announcement, it can also run mathematica, I want one like that. http://www.top500.org/list/2001/06/100 http://www.nvidia.com/object/personal_supercomputing.html http://tech.slashdot.org/article.pl?sid=08/11/23/068234&from=rss in plain english, that machine can run programs up to at the least 100 times faster.
