Hah.  Allow me to restate this.

Hah.

It is extraordinarily rare that an entity will give you permission to 
use their name in any advertising.  The most you can hope for is, 
generally, a press release.

Prestige does not translate into (profitable) revenue.

Hmmm ....

I think there may be a fundamental disconnect between the assumptions of 
folks in academia and the reality of this particular market.  I am not 
bashing on Prentis.  I would like to point out that the "much larger 
margins" in a cutthroat business such as clusters are ... er ... not 
much larger.

I could bore people with anecdotes, but the fundamental take home 
message is, if you believe this (much larger margins bit), you are mistaken.

The market for commercial HPC is under intense downward price pressure. 
  More so than ever before.  Companies, when they have money to spend, 
want to spend less of it, and get the same or better systems/performance 
than in the past.

What we are seeing is a fundamental change of business model, over to 
one that keeps upfront capital costs as low as possible, and pushes 
things to expense columns.

This is in part what is driving the significant interest in accelerators 
/APUs, and in remote cycle rental.  The costs associated with powering 
and cooling accelerators are minimal as compared to small/mid sized 
clusters.  The costs associated with very large clusters can be made 
into pure on-demand expenses with remote cycle rental.

Don't sell the folks at TJ Watson/IBM Research short.  They are a very 
bright group.  The co-R&D elements are a way IBM can dominate the HPC 
bits at the high end, and provide something that looks like an in-kind 
contribution type of model so that LANL and others can go to their 
granting agencies and get either more money, or fulfill specific 
contract points.

IBM is a business, and in most cases, won't generally have a particular 
business unit make a loss for "prestige" points.  That doesn't make the 
board/shareholders happy.

Well part of that is to prevent shopping the quote.  We see this *all* 
the time.  Someone asks for a quote, you provide it.  They then go and 
take your quote, elide specific company information, and then send it 
around asking others to beat it.

An NDA gives you a mechanism to stop this with a specific legal 
enjoinder from discussing terms.  Copyrighting quotes and specifically 
restricting redistribution of content and information contained is 
another method.
