Not sure if this will work for your computing needs, but take a look at the NVIDIA Tesla coprocessor. <a href="http://www.nvidia.com/object/tesla_computing_solutions.html">http://www.nvidia.com/object/tesla_computing_solutions.html</a><br>
<br>Basically, its 240 processor cores on a single PCIe board. Great for highly parallel computation. Also, its cheap.. around $1500 or so.<br><br><div class="gmail_quote">On Tue, Jul 7, 2009 at 9:29 AM, Mike Miller <span dir="ltr"><<a href="mailto:mbmiller%2Bl@gmail.com">mbmiller+l@gmail.com</a>></span> wrote:<br>

our statistical analyses. It would be good to have 50-100 cores. What is<br>
the cheapest way to go? About 4GB RAM per core should be more than<br>
enough. I'm thinking quad-core chips are going to be cheaper. How many<br>
sockets per mobo? I guess 1-, 2- and 4-socket mobos are available. We<br>
don't need SMP, but we'll take it if it is cheap (which I doubt). We'll<br>
use cloned HDDs in these boxes. My first thought is "blade" but maybe<br>
blades are more expensive than somewhat less convenient ways of housing<br>
the mobos.<br>
<br>
We have people here to house it and manage it and to pay for<br>
electricity(!). They also will have ideas about what we should buy.<br>
<br>
Any ideas?<br>
<br>
Which CPU gives the most flops/dollar these days?<br>
