Microsoft has technology for distributed search

I wouldn't assume Microsoft Bing is using Google technology for Bing. A quick review of the Microsoft Research web site will find a compelling technology and programming environment known as Dryad and Dryad LINQ ( language inline native query ) that offers another way to get the functionality many people find useful in Hadoop.

I think the comment in the article relative to the use of Hadoop in Bing is a bit of flame bait and opinion, not a fact.

Ballmer's Yahoo! bullishness hides Bing brand play

Try Bing before you disparage it??

The article is a bit unfair to Bing, It does contain some significant new technology. The quality of search results has improved and it does have the feature of streaming image results. So... if your looking for an image you will find Bing much better than Google.

Windows HPC server courts supercomputing greenhorns

A few facts to add to the discussion

A couple of points of information that could help inform the discussion:

1) Microsoft pricing for Academic customers is very reasonable and the per system licensing cost is a tiny fraction of the numbers mentioned in the original article. In the academic market, Windows is about equal in price to Linux.

2) Windows is performance competitive with Linux, in fact the highest efficiency top 500 system is currently at #40 coming in at 85% of peak and running Windows Server 2008.

3) HPC uses in the Financial services market go beyond derivative pricing, and the biggest consumers of CPU cycles are stochastic models that provide a probability estimate of future value. This occurs in Insurance, Banking and Capital Markets.

Full Disclosure, a significant portion of my income comes from Microsoft products.
