In March 2004 the Spanish government and IBM signed an agreement to build one of the the fastest computer in Europe. In July 2006 its capacity has been increased due to be the large demand of scientific projects.
MareNostrum is a supercomputer based on processors PowerPC, the architecture BladeCenter, a Linux system and a Myrinet interconnection. These four technologies configure the base of an architecture and design that will have a big impact in the future of supercomputing.
See below a summary of the system:
- Peak Performance of 94,21 Teraflops
- 10240 IBM Power PC 970MP processors at 2.3 GHz (2560 JS21 blades)
- 20 TB of main memory
- 390 + 90 TB of disk storage
- Interconnection networks:
- Myrinet and Gigabit Ethernet
- Linux: SuSe Distribution
MareNostrum has 44 racks and takes up a space of 120m2. In the following figure you will see the floor where the supercomputer is located.
