Hello, according to the web page, the card can use single or double precision and it is at the level of the so called IEEE 754 single & double. Which I believe is quite enough, and they say that mathematica can run on these devices. http://www.nvidia.com/object/product_tesla_s1070_us.html there is a tab with technical specs. Simon Plouffe 2008/11/24 Robert Baillie <rjbaillie@frii.com>:
this is, indeed, exciting news. but, a caveat and a question:
1. to see the advertised speedup, you need to implement highly parallel algorithms.
2. what's the word length of a variable on the graphics board? i did some work with graphics processing earlier this year, and there, a floating-point variable had only 18 bits of accuracy, not 23 that standard floats in C have (and even 23 is pretty borderline, if you ask me).

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.

in plain english, that machine can run programs up to at the least 100 times faster.
