On 21 April 2009 Intel corporation held an “Intelligent Processors” event which highlighted Intel’s next generation chip architecture and the industry leading companies who are incorporating this technology into their products.   The event, pulled together by Nigel Ballard of Intel, included demos by companies like Endeca, Cisco, Cray, Dell, HP, Oracle, VMware, Microsoft and Sun.  Nineteen hardware partners showed off Xeon 5500-based server products at this event.  Clearly Nigel is a man with convening authority.  When he calls, the big guns of the IT community come.

There were two other big draws at this event.  One was the Intel CTO, Justin Rattner.  I’ll be running a separate article on my interview of Justin shortly.  For now I’ll just say it was great having the new Nehalem Microarchitecture placed in context by a CTO of his stature.  He provided a keynote that underscored not only the technology of this smart server processor, but hit on the importance of innovating in a downturn.  His message was very clear and it is one I believe.  Now is the time to transform computing.

There were two other big draws at this event.  One was the Intel CTO, Justin Rattner.  I’ll be running a separate article on my interview of Justin shortly.  For now I’ll just say it was great having the new Nehalem
Microarchitecture placed in context by a CTO of his stature.  He
provided a keynote that underscored not only the technology of this
smart server processor, but hit on the importance of innovating in a
downturn.  His message was very clear and it is one I believe.  Now is
the time to transform computing.

Eric Doyle, Intel’s enterprise Marketing Manager, provided a deeper
dive into the power of real offerings based on the new chip, especially
the Intel Xeon 5500 (I
meant to ask Eric if he can shed some light on why the codename for
this project was called Nahelem, since he said he lives in Oregon I
wonder if he named it?).

The following are a few notes that combine things Justin Rattner and Eric Doyle said:

The Xeon 5500 based on the Nehalem project is  really the next era
for computer chips, providing the biggest jump in productivity and
efficiency since the Pentium Pro.    The Nehalem is hitting the market
right now (you can get one for your house if you buy a MacPro).  The
server based on the Nehalem is Xeon 5500.

The design of Nahalem is based on quad core design with two
executable threads per core.  The design also provides an added degree
of intelligence to how things are done on the chip.  Little processors
on the chip oversee and manage the big processors in the chip and that
concept allows for some very significant improvements to computing. 
For example, energy efficiency is far more adaptable/configurable. 
When you don’t need full processing power, less power is drawn.  New
virtualization capabilities are also enabled with this approach.

The result is that the Xeon 5500 provides the largest jump in
computer performance in Intel’s history.  In fact, this jump is the
greatest performance leap in computer history.  This jump is not just
because of more transistors on the chip, it is because of a very smart
design involving more cores.

This chip also provides features that will enhance trustworthy
computing.  I found this especially interesting and the whole
discussion left me feeling far more upbeat about the future of IT.   I
have no doubt security will still be a constant battle well into the
future, but with this new design the ability to run cryptographic
algorithms is sped up significantly.  This design enables a 40%
improvement in OpenSSL performance and a 50% improvement in RSA2048,
for example.  New capabilities will soon be enabled that leverage the
chip’s management capabilities to attest to true endpoint state.  This
will enable enhanced defenses against rootkits.

A few other bullets on Nehalem, from the Intel website:
Intel® microarchitecture, codenamed Nehalem, offers the latest in processor innovation, including:

  • Dynamic scalability, managed cores, threads, cache, interfaces, and power for energy-efficient performance on-demand.
  • Design and performance scalability for servers, workstations,
    notebooks, and desktops with support for 2-8+ cores and up to 16+
    threads with Intel® Hyper-Threading Technology (Intel® HT Technology),
    and scalable cache sizes, system interconnects, and integrated memory
    controllers.
  • Intelligent performance on-demand with Intel® Turbo Boost
    Technology taking advantage of the processor’s power and thermal
    headroom. This enables increased performance of both multi-threaded and
    single-threaded workloads.
  • Increased performance on highly-threaded applications with Intel
    HT Technology, bringing high-performance applications into mainstream
    computing with 1-16+ threads optimized for new generation multi-core
    processor architecture.
  • Scalable shared memory features memory distributed to each
    processor with integrated memory controllers and Intel QuickPath
    Technology high-speed point-to-point interconnects to unleash the
    performance of future versions of next-generation Intel® multi-core
    processors.
  • Multi-level shared cache improves performance and efficiency by reducing latency to frequently used data.

What is the “so what” of all the above?  Upgrade your old servers
now.  It will save energy, it will save space, it will reduce operating
cost, it will increase security, and it will enable more advanced
applications.

As for the many demos seen at this event, my favorite was the one
presented by my friends at Endeca.  Endeca is one of the first
companies fielding capabilities that can take maximum advantage of
Nehalem.   The speed, scale and scope of the data they can parse and
enable interaction with is incredible.  If you are considering an
Endeca deployment, consider Xeon 5500.  Ask Endeca for the demo and you will see why.  It just makes total sense.

Soon I’ll post a few more thoughts based on my interview of Justin Rattner.  Say tuned and happy computing!
