obtained with Linpack and GotoBLAS, with tuning for Nehalem not yet
completed.

Does someone know whether Intel has already started shipping Nehalem Xeon
55** processors? Are there system integrators that have Nehalem servers
already available for customers?
How these Xeon 55** are compared to latest AMD Shanghais (clock by clock,
performace/price)?

Yes, Intel has provided seed units to system integrators and software
developers so they can start system and code testing.
However, those samples are covered by NDA that does not allow
performance measurements to be published, including comparisons with
competing products.
Only Intel can

intel?

Nope. They just track people who talk badly about Intel and
then they send around the black helicopters and the little blue

Often companies like Intel have an embargo date solely to make sure
that all the great new performance news arrives at once, generating a
lot of press alongside the formal announcement of availability.
I also had one case years ago where I was doing a
I feel it's a double edged sword.
Usually when intel ships a great new part, all the sites are
discussing it and 1 or 2 vague tests show up.
AMD seems to use the path you describe below.

Suddenly opteron was there at 2.2Ghz

They are _definitively_ worth waiting for,
although I am not familiar with the release
timing. But I have been running on a dual-socket
with 8 cores and 16 SMTs. And I say they are worth waiting for.

If integrators have them, this means that the Nehalem release is imminent?
But when?

I am still in process of purchasing a new cluster and consider whether is
worth waiting for new Intel Xeons. Does someone know when Intel will start
selling Xeons based on Nehalem architecture? They announced desktop launch
(Nov 16) but were quiet about server release.
