BSC’s MareNostrum 4 Supercomputer to be 12 Times More Powerful Than MareNostrum 3

November 29, 2016

Nov. 29 — MareNostrum 4, the new supercomputer of the Barcelona Supercomputing Center (BSC), will be 12.4 times more powerful than the current MareNostrum 3. The centre 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.

This purchase is to be made from IBM, which will integrate in one sole machine its own technologies alongside those of Lenovo, Intel and Fujitsu. The contract has been awarded following a public tender process in which two other companies participated. The contract value is of almost €30 million.

General purpose and emerging technologies

With this purchase, BSC-CNS has pursued a dual objective: to acquire a general-purpose machine capable of executing all types of scientific and engineering tasks, and to provide itself with clusters built with emerging technologies. These clusters will serve users’ needs and, in turn, will allow the centre to test and analyse the performance of the most recent developments in the field of supercomputing.

Greater energy efficiency

To this end, the new machine will have two distinct parts. The general purpose element, provided by Lenovo, 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, which is to say that it will be able to perform more than 11,000 trillion operations per second, ten times more than the MareNostrum3, which was installed between 2012 and 2013. Despite this increase in capacity, it will consume only 30% more power, reaching 1.3 MW/year.

Emerging technologies

The second element of MareNostrum 4 will be formed of clusters of three different 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 of the new generation of pre-exascale supercomputers.

One of these clusters will consist of IBM POWER9 processors and NVIDIA GPUs, which are the same components that IBM and NVIDIA will use for the Summit and Sierra supercomputers that the US Department of Energy has commissioned for the Oak Ridge and Lawrence Livermore National Laboratories. Its computing power will be over 1.5 Petaflop/s.

The second cluster will be made up of Intel Knights Landing (KNL) and Intel Knights Hill (KNH) processors provided by Fujitsu and Lenovo respectively. They are the same processors that will be inside the Theta and Aurora supercomputers purchased by the US Department of Energy for the Argonne National Laboratory. Its computing power will be in excess of 0.5 Petaflop/s.

Finally, a third cluster will be formed of 64 bit ARMv8 processors that Fujitsu will provide in a prototype machine, using state-of-the-art technologies from the Japanese Post-K supercomputer. This cluster’s computing power will also be over 0.5 Petaflop/s. 

The goal of the progressive incorporation of these emerging technologies into MareNostrum4 is to enable BSC to operate with what are expected to be some of the most state-of-the-art developments of the coming years and to test if they are suitable for future versions of MareNostrum.

Disc Storage

MareNostrum4 will have a disk storage capacity exceeding 10 Petabytes and will be connected to the Big Data infrastructures of BSC-CNS, which have a total capacity of 24.6 Petabytes. Like its predecessors, MareNostrum4 will also be connected to the network of European research centres and universities through the RedIris and Geant networks.

PRACE and the Spanish Supercomputing Network

The path towards the upgrade of the MareNostrum supercomputer began with a decision taken by the Spanish Council of Ministers at its meetings of 4 and 18 December 2015. The decision authorised the budget adjustments necessary for the Ministry of Economy and Competitiveness to contribute €34 million plus VAT to BSC for the purchase of MareNostrum 4. €30 million of this sum has been allocated for the purchase of MareNostrum 4’s calculation clusters and for work on the electrical and cooling systems necessary for the computer to function correctly. The remaining €4 million has been used for MareNostrum 4’s parallel disc system.

Like its predecessor MareNostrum 3, the new supercomputer will be part of the Partnership for Advanced Computing in Europe (PRACE), a network which has the objective of creating a European high performance computing infrastructure.

The arrival of MareNostrum 4 will allow for a new phase of the PRACE European supercomputing project in which Spain will be able to maintain its status of core member alongside Germany, France, Italy and Switzerland, the latter having recently joined the network.

MareNostrum 4 will also be part of the Spanish ICTS network of unique scientific and technological infrastructures in Spain and of the Spanish Supercomputing Network (RES). The new supercomputer will increase RES’s calculation capacity and will replace MareNostrum 3, the components of which will be distributed among various nodes of the network.

Brief history of MareNostrum      

MareNostrum is the generic name used by BSC for the various versions of its most emblematic supercomputer. The MareNostrum machines have served over three thousand scientific and technical research projects since the first version was installed in 2004. At the time, MareNostrum had a calculation capacity of 42.35 Teraflop/s (42.35 trillion operations per second). In 2006, it was upgraded and doubled its capacity to 94.21 Teraflop/s. Since the last upgrade (2012-2013), MareNostrum 3 has had a peak performance of 1,1 Petaflop/s (eleven hundred trillion operations per second).

MareNostrum is a facility at the service of the scientific community and of society. Supercomputers are now one of the fundamental pillars of science and engineering. Without them, it would be impossible to carry out a significant amount of research and a substantial number of the projects which require a large capacity for calculation and data handling. They are used to create models and simulations, and to manage vast quantities of information generated by studies in all scientific areas.

About Barcelona Supercomputing Center

Barcelona Supercomputing Center is Spain’s leading supercomputing centre and specialises in High Performance Computing. Its mission is twofold: to offer supercomputing infrastructure and services to European and Spanish scientists, and to generate knowledge and technology that can be applied for the benefit of society.

BSC is a Severo Ochoa Center of Excellence and a first level hosting member of the European research infrastructure PRACE (Partnership for Advanced Computing in Europe). BSC also manages the Spanish Supercomputing Network (RES). 

The consortium which manages BSC consists of the Spanish Ministry of Economy, Industry and Competitiveness (60% share); the Department of Economy and Knowledge of the Generalitat de Catalunya (30%) and the Technical University of Catalonia-BarcelonaTech (10%).
