A stroll through Marenostrum IV computing resources

2017-11-11T13:39:20+00:00 September 18th, 2017|

Enclosed you will find the slides that I used in my last visit to the Torre Girona chapel with UPC students. The slides show the awesome computational power of the Marenostrum IV supercomputer and the presentation of the architecture required to get it.  I have posted these transparencies (and photo) for my students as I promised them. But anyone who wants to know a little more about the Marenostrum can take a look at them to realize the magnitude of this supercomputer.      SLIDESHARE slides <blockquote>In reality, this post was intended for my UPC course's students, although I think it may be of interest to other students.</blockquote>

Marenostrum 4 will come in production on July 1st

2017-08-17T16:34:28+00:00 June 29th, 2017|

    Today, Sergi Girona, Operations Director at BSC,  inform as that on July 1st  MareNostrum 4 will come in real production for the first research projects that uses the general purpose block of Marenostrum 4. Great new!  I want to thanks the Operations department for their maratonian work. MareNostrum IV peak power is 11.15 Petaflops, or what is the same, it is able to perform more than eleven thousand trillion operations per second, ten times more than the MareNostrum3, which was installed between 2012 and 2013. Although its power is ten times greater than that of its predecessor, it only increases energy consumption by a 30% and now is of 1.3 MWatt/year. It have two distinct parts: General Purpose part and Emerging Technologies part. General Purpose  MareNostrum IV is a supercomputer based [...]

Caffe2: A new player on the scene of Deep Learning frameworks

2017-08-17T16:34:41+00:00 April 25th, 2017|

Few days ago Facebook announced Caffe2, a new open-source, cross-platform framework for deep learning. They say that Caffe2 is the successor to Caffe ( really?), the deep learning framework developed by Berkeley AI Research and community contributors. Caffe2’s GitHub page describes it as “an experimental refactoring of Caffe that allows a more flexible way to organize computation.” As my readers know, when appeared TensorFlow I decided to pay attention to it because it could change the scene of DL/AI frameworks. Now, we are in the same situation, Caffe2 could change the current scene that Francesc Sastre, one of my master students,  build for his master thesis:  "Frameworks popularity evolution in GitHub" No questions, right? Facebook launched Caffe2, an open-source deep learning framework made with expression, speed, and modularity in mind. It address the bottlenecks observed [...]

Marenostrum pictures from a great photographer and a good friend

2017-08-17T16:34:53+00:00 December 16th, 2016|

Last week Adrià, a good friend and former student of the FIB, visited the chapel of Marenostrum. Among many of his skills, he is a great photographer. I attached here some of his pictures of the visit. Great job, right? You can find more information about Adrià's work in his flirk web page. As you can deduce Adrià is the author of the new picture of my personal web page. Thank you Adrià!.

A new Supercomputer will arrive at Barcelona soon

2017-08-08T22:38:38+00:00 November 29th, 2016|

EN  BSC-CNS has just approved the purchase of a new supercomputer that will have a performance capacity of 13, 7 Petaflop/s and will be located in the Torre Girona chapel, home to its predecessors, the MareNostrum 1, 2 and 3. Marenostrum 4 will have two distinct parts. The general purpose element will have 48 racks with more than 3,400 nodes with next generation Intel Xeon processors and a central memory of 390 Terabytes. Its peak power will be over 11 Petaflop/s. The second element of MareNostrum 4 will be formed of clusters of three emerging technologies that will be added and updated as they become available. These are technologies currently being developed in the US and Japan to accelerate the arrival [...]

‘MareNostrum’: la supercomputadora capaz de realizar 1.100 billones de operaciones por segundo

2017-08-08T22:42:11+00:00 May 2nd, 2016|

Hoy en El País en su sección "protagonistas One" de su canal de youtube presentan una entrevista titulada "'MareNostrum': la supercomputadora capaz de realizar 1.100 billones de operaciones por segundo" en que me han ascendido al cargo de "Investigador jefe del Barcelona Supercomputing Center". Cuando se entere mi jefe creo que se acabó la historia!  :-). Pero habrá valido la pena estos minutos de gloria hasta que me echen, porque creo que ha quedado un documento fantástico que aporta valor, a pesar que fue una entrevista que me costo un poco, dado el "aquí te pillo, aquí te mato" (o simplemente despiste mío de no saber a donde iba. Ya ven, me pillaron con ropa de trabajo, sin traje ni corbata! :-( ). Sin duda el mérito es del equipo [...]

Mateo Valero Creu de Sant Jordi de la Generalitat a Mateo Valero

2017-08-08T22:45:48+00:00 April 12th, 2016|

Fantàstic!!!!! Avui s'ha fet públic la concessió de la Creu de Sant Jordi d'enguany al director del BSC-CNS, Mateo Valero, “pel seu treball en l’àmbit de l’arquitectura de computadors, pel qual ha rebut prestigiosos premis internacionals, entre els quals l’Eckert-Mauchly 2007”. El paràgraf anterior està bé, però m'agradaria ser més prosaic i dir que se la mereix amb escreix perquè és un pencaire que ha aportat molt de valor al País. Per posar un exemple molt evident, entre molts, aconseguir que Barcelona sigui referent mundial de la Supercomputació amb un gran centre de recerca que aporta molt de valor, directe i indirectament, a la economia i projecció d'aquest País. Això té molt de valor, que ningú ho dubti. Feliciteu-lo, perquè sens dubte s'ho mereix i fins i tot permeteu-me dir que ja trigavem! Si voleu més detall, [...]

You recently published a book called “First Contact with TensorFlow”. First of all, why this book is freely available on-line? I hope this book adds some value to this world of education that I love so much. I think that knowledge is liberation and should be accessible to all. For this reason, the content of this book will be available on this website completely free.  Of course, if the reader prefers to opt for a paper copy, you can purchase the book through Amazon or Lulu portals. What is your book about? As the title indicates, it is a first contact with TensorFlow , to get started with Deep Learning programming.  A few months ago, Google offered to the community, as an open source, its  Machine Learning engine (with name TensorFlow) that can be used [...]

The Research Group Autonomic Systems and eBusiness Platforms at Barcelona Supercomputing Center (BSC), invites outstanding candidates to apply for a full-time PhD position under "Becas de posgrado de La Caixa"  grants (link) or "International PhD Program Fellowship BSC La Caixa" grants (link). The PhD work will focus on Deep Learning and High Performance Computing for computer vision. PhD project description Deep learning has changed the scape of computer vision and artificial intelligence. Current research in these areas has shown the possibility of creating tools that are able to recognize thousands of objects, or automatically describe the content in an image. For example, Google Brain approach to automatic captioning is able to reliably describe many complex images using this basic queues. However, human understanding of images is far more elaborated. Humans do not [...]

Dear readers, I’m a little bit late posting this information, but I have been up to my eyes with work!. Few weeks ago I attended the European Spark Summit held in Amsterdam. It was a wonderful opportunity to meet and talk with the spark community. The summit started with Matei Zaharia, who talked about how spark usage is evolving and Ion Stoica talking about how Spark is entering into enterprises. There were a lot of interesting presentations. You can download them and see the recorded video presentations on this web site. BSC also gave a presentation where we presented what we are doing with Spark in our research supercomputing center in Barcelona. Below you can find the slides that we presented. Attending the summit also gave us the opportunity [...]

What we mean by/Qué queremos decir con “High-Performance Big-Data Analytics”?

2017-08-09T12:15:33+00:00 November 21st, 2015|

    ES    Hoy en día nos encontramos inmersos en un nuevo proceso en el que las "cosas" pasan del mundo físico al mundo digital y son accesibles desde cualquier dispositivo electrónico. El Cloud Computing es lo que hace posible que la tecnología digital penetre en todos los rincones de nuestra economía y la sociedad. Este nuevo escenario no sólo permite a los usuarios conectarse a través de sus dispositivos móviles al mundo digital que se avecina, sino que empieza también a permitir la conexión de cualquier objeto o dispositivo. Esto causará un diluvio de información digital, que se conoce como Big Data. Existen actualmente diferentes frameworks Big Data de código abierto que proporcionan los medios para lidiar con este diluvio de datos. Estos frameworks permiten abstraer [...]
