No es por quitarles mérito ... pero no es la primera supercomputadora

¿A que se refieren con lo de hibrida? No me he dado cuenta de si se ha
dicho :-?


La computación híbrida es cuando mezclas procesadores de distinto tipo. En el
caso de RoadRunner:

"Two IBM QS22 blade servers and one IBM LS21 blade server
are combined into a specialized "tri-blade" configuration
for Roadrunner."

Es decir:

- RoadRunner es un cluster, no es _una_ máquina

- es un cluster compuesto por tri-blades (aquí es donde
entra la computación híbrida)

- en el triblade se mezclan procesadores Cell y AMD

No puedo dar muchos más detalles por que no sé cómo se interconecta todo, la
memoria, los buses, ...

Como decía esto no es nuevo ni es la primera vez que se hace,

Error!

Hay algo nuevo, y es la plataforma de interconección Torrenza:

http://www.idg.es/computerworld/articulo.asp?id=179042

AMD anunció para su próxima generación de procesadores Opteron la
incorporación de 3 nuevas tecnologías como son Trinity, Radien y
Torrenza. Pues bien, hoy, ya se conocen los pormenores de ésta última,
que está disponible en todo el mundo y que la propia AMD definide como
una plataforma multisocket abierta, destinada al entorno servidor,
plataforma en la cual otras compañías importantes pueden también
montar sus propios procesadores o co-procesadores multipropósito,
usando para éste propósito, tecnologías de AMD como AMD64, Direct
Connect y HyperTransport.
Dentro de la propia AMD, nadie duda de que la nueva plataforma tendrá
un efecto positivo en la labor de los administradores de centros de
datos ya que, según señala Marty Seyer, vicepresidente senior del
departamento comercial de AMD, "se verán beneficiados por la
cooperación optimizada a nivel de plataforma, con nuevos niveles de
estabilidad, posibilidad de ampliación, flexibilidad y propiedades de
plataforma para la infraestructura de su servidor, entre otras
características".
Aunque en teoría Torrenza "está orientada a fabricantes de CPUs,
tarjetas gráficas o chipsets", como señala Alejandro Ruiz Bueno,
director de desarrollo de negocio de AMD para España y Portugal, son
ya varios los proveedores de la industria como "HP, IBM, Dell, Sun
Microsystems, Fujitsu Siemens Computer, Tyan, o Supermicro, entre
otros, los que han mostrado su interés por trabajar sobre Torrenza
como plataforma abierta", tras haber aplaudido enérgicamente la
iniciativa de AMD.

Primera referencia
AMD también ha hecho pública la primera referencia en la utilización
de esta tecnología, que no será otra que el superordenador Roadrunner
de IBM, desarrollado por el Gigante Azul para el departamento de
Administración de la Seguridad Nacional de Energía Nuclear en Estados
Unidos.
Este superordenador llevará 16 mil procesadores AMD Opteron en
servidores x3755 con más de 16 mil procesadores Cell de IBM en
unidades Blade Center H con enlaces Hypertransport entre ellos. El
Roadrunner confiará en los procesadores Opteron de AMD para procesar
los datos de entrada y salida (IO) y la actividad de las
comunicaciones mientras que los cálculos más complejos los harán los
procesadores Cell de IBM, que cuentan con 8 cores cada uno.
Aunque el fabricante no lanza previsiones en cuanto a la adopción de
esta plataforma, el portavoz local insiste en que "desde AMD España
ayudaremos a aquellos que quieran empezar a desarrollar sobre Torrenza
para tener referencias lo antes posible", augurando un buen futuro a
este lanzamiento.

How it Works

Roadrunner's hybrid design will allow the system to segment complex
mathematical equations, routing each segment to the part of the system
that can most efficiently handle it. Typical compute processes, file
IO, and communication activity will be handled by AMD Opteron
processors while more complex and repetitive elements -- ones that
traditionally consume the majority of supercomputer resources -- will
be directed to the more than 16,000 Cell B.E. processors. Designed
originally for gaming platforms, where intense graphics and real-time
responsiveness are key, the Cell B.E. processor is ideal to speed
Roadrunner through intense mathematical problems.

"This new supercomputer demonstrates a commitment to achieve a major
advance in technological capability that will help enable scientists
and businesses solve the most challenging problems," said Bill
Zeitler, senior vice president, IBM Systems and Technology Group. "Los
Alamos is a valued partner as we embark on this exciting journey."

"This installation with Los Alamos and IBM demonstrates the compelling
benefits from industry leaders innovating around an open platform; in
this case IBM and AMD collaborating in the use of AMD Opteron and the
Cell B.E. processor to build powerful systems for highly specific Los
Alamos Labs workloads," said Marty Seyer, senior vice president,
Commercial Segment, AMD. "This is an excellent demonstration of
Torrenza in action -- building on the performance and
performance-per-watt advantages AMD delivers to create incredible
value in leveraging HyperTransport technology to redefine how
different systems, based on different processor platforms, can
communicate with each other to solve some of the most complex
computing problems."

Torrenza represents the industry's first open, customer-centric x86
innovation platform, capitalizing on the Direct Connect Architecture
and the AMD64 platform to enable other processor and hardware
providers to innovate within a common ecosystem.

This collaboration allows partners with acceleration technology to
increase system performance, scalability, and flexibility. And because
end customers value openness and freedom of choice, Torrenza helps
enrich the IT industry.

At AMD, we have made a commitment to open AMD64 technology and the AMD
Opteron™ processor platform to collaboration from a broad community of
innovators, including hardware manufacturers and software developers.

As an open environment, Torrenza was conceived to enable:

* Tight coupling of accelerator coprocessors and option cards to
AMD64 technology-based systems
* Enhanced protocols to make accelerators more effective

AMD encourages innovation by the sharing of technology. As an example,
the Torrenza Innovation Socket enables OEMs to develop their own
silicon to take full advantage of an x86 environment and the
accompanying economics associated with packaging, chipsets, and
motherboards designs.

Through the Torrenza initiative, AMD has shared the AMD64 processor
socket design and specifications to OEMs to allow collaboration on
specifications and to take full advantage of Direct Connect
Architecture.

Torrenza is designed to reduce complexity for customers while
increasing the pace of innovation in both silicon and platforms.
Collaboration between AMD and the community of innovators will help
provide datacenter managers with new levels of platform stability,
upgradeability, and flexibility for their server infrastructure.
Stream Computing

Stream computing harnesses the tremendous processing power of graphic
processors for high performance, data-intensive computing in a wide
range of scientific, business, and consumer applications.

This provides organizations with the ability to process massive
amounts of information in significantly less time.

Advanced Research

AMD has teamed with the Computer Architecture Group at the University
of Mannheim to establish the Center of Excellence for HyperTransport.
Research at the Center will benefit the academic community and the
next generation of solutions that leverages HyperTransport™
technology.

The Center of Excellence has released an HTX reference board for
universities and companies that research compute-intensive testing and
design applications. Research projects focus on both non-coherent and
coherent HyperTransport, helping to support an open standards approach
to innovation. The University of Mannheim is also a licensee of
coherent HyperTransport.

HyperTransport™ Technology Consortium

The HyperTransport Technology Consortium controls, licenses, and
promotes HyperTransport technology industry-wide. Since its inception
in 2001, the Consortium has expanded to more than 60 members
worldwide, including technology leaders such as AMD, Apple, Broadcomm,
Cisco, Cray, Dell, IBM, NEC, Nvidia, Renesas, and Sun Microsystems.

OpenFPGA Consortium

OpenFPGA is a non-profit consortium focused on accelerating the
adoption and incorporation of reconfigurable computing solutions in
high performance and enterprise computing.

The consortium serves the worldwide community through collaborative
