HPC. Recopilación de enlaces mayo y junio 2015.

Aunque seguramente el lector ya lo sabe, HPC son las siglas de High Performance Computing, sector que incluye a las tecnologías de Supercomputadores, Data centers, es decir grandes sistemas de computación avanzada.

1. El informe IDC 2013 sobre el mercado HPC y sus tendencias.

Es el más reciente que he encontrado.

2. El sector HPC, clave para la competitividad de EEUU.

El enlace lo es a un artículo de la revista on-line Scientific Computing World en el que hablan sobre un estudio que realizó en octubre de 2014 la consultora Intersect360.

The US needs to invest in high-performance computing (HPC) so that its industry can continue to stay competitive in global marketplaces, according to a report from the market consultancy company Intersect 360, entitled ‘The Exascale Effect: the Benefits of Supercomputing Investment for U.S. Industry.’

The work was carried out on behalf of the US Council on Competitiveness, a non-partisan, non-governmental organisation, composed of corporate CEOs, university presidents, labour leaders and national laboratory directors.

Its aim is to ‘set an action agenda to drive US competitiveness, while generating innovative public policy solutions for a more prosperous America’.

The new analysis comes just two months after a Task Force on High Performance Computing reported to the US Department of Energy that data-centric computing, in conjunction with exascale, will be one of the most important requirements of HPC within the next 10 years.

Intersect’s report states: ‘High performance computing is inextricably linked to innovation, fuelling breakthroughs in science, engineering, and business. HPC is viewed as a cost-effective tool for speeding up the R&D process, and two-thirds of all US-based companies that use HPC say that “increasing performance of computational models is a matter of competitive survival.”’

The report identifies HPC as a key tool for the US to stay competitive in many industries, not just on an academic and government research level.

It is based on the research conducted by Intersect360, consisting of 14 in-depth interviews with representatives of industrial HPC organisations and 101 responses to a comprehensive online survey of US-based companies that use HPC. Among the key findings, was the statement that: ‘US industry representatives are confident that their organisations could consume up to 1,000-fold increases in computing capability and capacity in a relatively short amount of time.’

Increasing the computational power of today’s petaflop systems, by several orders of magnitude, may be the easiest route to added value for industry, but there are several technology roadblocks that prevent the current technology from being scaled as HPC users do today.

The Exascale Effect: the Benefits of Supercomputing Investment for U.S. Industry. 

Extracto (con comentarios).

Para cualquier nivel de desarrollo, hay necesidad de más capacidad de computación:

Although they struggle to predict the specific discoveries and innovations that will come about, U.S. industry representatives are confident that their organizations could consume up to 1,000-fold increases in computing capability and capacity in a relatively short amount of time.

El mayor cuello de botella ahora mismo es el software.

Software scalability is the most significant limiting factor in achieving the next 10x improvements in performance, and it remains one of the most significant factors in reaching 1,000x

En EEUU se considera que el impulso del gobierno es importante.

U.S. industry sees a benefit from government leadership in the investment in supercomputing technologies, but the links between government and industry need to be strengthened.

3. HPC en Irlanda.

Si países del tamaño de EEUU tienen clara su apuesta por la tecnología HPC (también la R.P. China por ejemplo), la posición de otros, como Irlanda, está menos clara.

ICHEC was founded in 2005 as Ireland’s national high performance computing centre. Its mission is to provide HPC resources, support, education and training for researchers in Irish institutions and also to support Irish industries and contribute to the development of the Irish economy.

Some of the fruits of the work supported by ICHEC in partnership with PRACE were discussed in a special session during the PRACE event, entitled “HPC in industry in Ireland.”

Tullow Oil is a multinational oil and gas exploration company founded in Tullow, some 35 miles south of Dublin in Ireland, although its corporate headquarters are now in London. It relies on seismic imaging to locate oil supplies buried deep in rocks under the sea and on land. In its simplest form, it involves propagating sound waves through a substrate and then recording the time it takes for the wave to bounce back into geophones (microphones) to provide an indication of the materials the wave passed through.

Sean Delaney, a computational physicist at Tullow Oil, told a special session of PRACEdays15 on HPC in Ireland

Delaney said: “We have lots and lots of data, and computers just can’t get fast enough as far as the oil industry is concerned. The more horse power we can get our hands on, the more we can use at any given time. Small things matter, small improvements in resolution really do make a difference.”

4. Sobre programación paralela.

Hemos visto que uno de los cuellos de botella para el desarrollo de la industria HPC es ahora mismo el software. El lector puede hacerse una idea sobre la programación paralela en el siguiente libro.

Libro. Parallel Programming: for Multicore and Cluster Systems

5. Publicaciones on-line para seguimiento de mercado y tendencias en el sector HPC.

Recordamos al lector algunas de las publicaciones on-line que informan sobre el sector HPC.

–InsideHPC. Han cambiado el formato. Empezó como blog y ahora tiene más bien forma de revista on-line, con publicaciones por apartados.

–HPCWire.

The Platform.

Is a new publication, which formally launched February 23, 2015, in partnership with The Register. It will offer in-depth coverage of high-end computing at large enterprises, supercomputing centers, hyperscale data centers, and public clouds.

La introducción del editor.

It may be difficult some days to see the lines between servers, switches, and storage, but there are still distinctions that matter. So The Platform will track these technologies as elements of modern platforms under the Compute, Store, Connect, Control, Code, and Analyze sections.

Compute is where you will find processors and coprocessors and the software that virtualizes computing infrastructure.

Store is where all things relating to storage, from storage devices on up to file systems, will live.

Connect is all about networking in the datacenter, and

Control is focused on the management software to control systems, switches, clouds, clusters, and applications.

Code is where we cover the tools for creating applications, from compilers all the way up to platform cloud frameworks.

Analyze is a section devoted explicitly to the technologies created to do data analytics in its myriad forms.

For those who are looking for more of an industry breakdown, we will also sort content into HPC, Enterprise, Hyperscale, and Cloud sections based on their primary use case.

6. La feria SC15 y su sección Emerging Technologies.

Como es bien conocido en el sector HPC hay dos grandes ferias anuales.

Una, SC (SC (formerly Supercomputing), the International Conference for High Performance Computing, Networking, Storage and Analysis, is the name of the annual conference established in 1988 by the Association for Computing Machinery and the IEEE Computer Society), se desarrolla tradicionalmente en EEUU a mitad de año (junio o julio).

La otra, International Supercomputing Conference is a yearly conference on supercomputing which has been held in Europe since 1986. En general tienen lugar en Alemania.

Aprovechando estas dos conferencias se publican los resultados del Top500 y de otros rankings vinculados al sector (TopGreen y otros) .

Extracto de la página web de SC15. 

In the Emerging Technologies track of the Technical Program, SC15 will examine innovative solutions that may significantly change and extend the world of HPC in the next five to fifteen years. Consisting of panel sessions and competitively selected exhibits, Emerging Technologies will showcase technologies that are innovative but not yet available from industry as products. Technologies such as reconfigurable computing, new SoC designs, 3D memory technologies, non-volatile memory, alternative programming languages, and novel cooling techniques may offer medium-term benefits, while new device technologies such as carbon nanotubes, photonic interconnects, chip-level optical interconnects, quantum computing and next generation optical computers, offer potentially paradigm-changing benefits over the longer term.

The SC15 Emerging Technologies Committee will select these technologies from submissions, based on a peer-review process with a single round of reviews.  Successful projects will advocate future technologies with the potential to influence computing and society as a whole. Winners will receive free exhibit floor space in a high visibility location; this location will allow attendees the opportunity to witness technology demonstrations, see presentations, and hold in-depth technical discussions.

Actualmente están en estado de aceptación de envios de artículos para seleccionar aquellos que  se presentarán.

8.Los sistemas Shasta, Cray.

Es la nueva arquitectura que Cray introducirá dentro de algunos años.

Como se, en éste sector, las rutas de innovación están bastante planificadas.

Extracto.

We’ll continue to evolve the XC line through the 2018 Shasta introduction.

The Shasta network will have significantly higher performance and even lower diameter (ergo, low latency and bandwidth-efficient) than the groundbreaking Aries network in the Cray XC40 system. Using this network, we’ll be able to build truly balanced systems, where the network is tightly integrated and well matched to the processing nodes. High network bandwidth relative to local compute and memory bandwidth is key for sustained performance on real world codes, and a hallmark of Cray systems.

9. HPC awareness.

Entre las nuevas tendencias en HPC está el considerar como objeto de optimización nuevos parámetros que antes no se tenían en cuenta: el consumo eléctrico, la facilidad de programación….

Power and software aware systems.

Power and fault-tolerance.

Power aware datacenters.

Topology awareness.

10. Eurotech.

Es una de las empresas europeas (concretamente italiana) que operan en el sector HPC. Bull sería otra. Y que yo sepa no hay muchas más.
