MareNostrum (Catalan: [ˌmaɾəˈnɔstɾum], Spanish: [ˈmaɾeˈnostɾun]) is a supercomputer in the Barcelona Supercomputing Center, the most powerful in Spain and one of seven supercomputers in the Spanish Supercomputing Network. It was presented by IBM and María Jesús San Segundo, the Spanish Minister of Education and Science.
The supercomputer consists of 3,056 JS21 computing nodes, for a total of 48,896 Intel Sandy Bridge processors, and 84 Xeon Phi 5110P in 42 nodes, all running at 2.o3 GHz for 10,240 CPUs in total. MareNostrum has 36 racks dedicated to calculations. In total, each rack has a total of 1,344 cores and 2,688 GB of memory. Each IBM iDataPlex Compute rack is composed of 84 IBM iDataPlex dx360 M4 compute nodes and 4 Mellanox 36-port Managed FDR10 IB Switches. dx360 M4 compute nodes are grouped into a 2U Chassis, having two columns of 42 2U Chassis.
The computing nodes of MareNostrum communicate primarily through a high bandwidth, low latency InfiniBand FDR10 network. The different nodes are interconnected via fibre optic cables and Mellanox 648-port FDR10 Infiniband Core Switches. In addition, there is a more traditional local area network consisting of Gigabit Ethernet adapters.
MareNostrum runs SUSE Linux 11 SP3. It occupies only 120 m² (less than half a basketball court) and weighs 40,000 kg. The original installation was largely constructed in two months in San Fernando de Henares, Madrid (Madrid) and was installed in the Barcelona Supercomputing Center in Barcelona. It has since been upgraded twice, first in 2006, and then in 2012-2013 with additional processors to reach the current total.
The supercomputer is used in human genome research, protein research, astrophysical simulations, weather forecasting, geological or geophysical modeling, and the design of new drugs. It was booted up for the first time on 12 April 2005, and is available to the national and international scientific community.
Mare Nostrum ("our sea") was the Roman name for the Mediterranean Sea. The supercomputer is housed in the deconsecrated Chapel Torre Girona at the Polytechnic University of Catalonia, Barcelona, Spain.
