From: Quadibloc on 2 Sep 2008 16:54 The message header says it... There are a few other items I've heard of. There's the chip from ClearSpeed with 96 floating-point processors. There are a couple of GPU-based floating-point accelerator cards; one is forthcoming soon, one is here now but more expensive. There's the new version of the Cell microprocessor with better double- precision support. And there's the 16-processor Rock from Sun, and the Larabee architecture from Intel, with one big CPU and perhaps 32 small ones - which is going to come out as a GPU-substitute (where, I fear, it indeed may not perform well, as its detractors claim) before being used as a CPU (where I think its real potential lies). I suspect, though, that there are other high-performance technologies in development out there that I just haven't heard of. Even without exotic technologies, for example, there's the Mac Pro as the most readily available 8-core system (two Intel quad cores), and a company called BOXX, I've just found out today, makes workstations with four or sixteen quad-cores from AMD. And an outfit that makes a small compute server with many chips advertised in Linux Journal not long ago (came with Microsoft Windows Compute Server, though, ironically). John Savard

AMD is working on scaleable atomic transactions therefore making highly advanced non-blocking synchronization algorithms come to life on a mainstream platform...

General Purpose GUP programming is interesting. I mean why would I want to use a CPU to crunch a vector when I can transpose it onto a texture and render every pixel of that sucker!
