That article is merely a popularist comment on the original paper.
'nuff said.
A quick read of the original paper shows it to be both current
(2.6.35-rc3 kernel - for which they also developed some fixes)
and thorough.
To some extent it was artificial in that they constructed the tests
to do no

I think those are not a single CEC, but multiple independent CECs perhaps more
like a Parallel Sysplex in z/OS terms.

Of course, the article is all about Intel and Linux. But I wonder if similar
problems could occur on the 80 CP z196. If not, that would be a boon argument
to replace largely
It reminds me of an xkcd http://xkcd.com/619/
I don't think it will be a real selling point, when you are comparing similar
class machines. Kernel modifications have been done to address this on
specific Linux systems. However if you were to use it as a pointer to why this
class of machine

What about the massively parallel systems running Linux using

John,
Take a look at Microsoft's Midori Operating System initiative. Also, Amdahl's
Law in the multicore era.

Subject: Article on multi-code processors - does it apply to z196?

Tom,
Most of those are actually clusters of nodes with only a few cores, with
each node having it's own memory and OS instance. So, it's not one computer
with thousands of CPUs, but a network of thousands of computers, each having
2-8 CPUs.
