Magerit was first installed in 2006 and reached the 9th fastest in Europe and the 34th in the world,[2] the second best position of a Spanish supercomputer in the list.

The name comes from the Arabic name of a fortress built on the Manzanares River in the 9th century AD, and means "place of abundant water".

In May 2008, CeSViMa and Magerit supercomputer migrated to a new building 40°24′15.65″N 03°50′4.75″W / 40.4043472°N 3.8346528°W / 40.4043472; -3.8346528 in the same campus, only 500 meters from previous location at Computer Science School.

The computer was upgraded: change of communication switch, storage subsystem and replacement of some blades with a new version.

[citation needed] In the first half of 2011, the supercomputer was fully upgraded replacing all computer nodes and interconnexion networks with the latest technologies in only one month (a record time).

When this version enters in production it reach the 2nd of Spain, 9th of Europe and 34th of the world in the TOP500[2] list and the 275th position in the first Green500[13] list The final version setup (reached after the upgrade of 2008) is a cluster of 1204 nodes eServer BladeCenter (1036 JS20 and 168 JS21, both PowerPC 64-bit) under SUSE Linux Enterprise Server 9.

All the nodes are interconnected with a low latency (2.6 – 3.2 μs[15]) and high bandwidth network called Myrinet.

[4] When this setup enters in production stage in 2011, it reach the first position of Spain, 44th of Europe and 136th of the world.

The system maintains two independent Gigabit Ethernet for auxiliary tasks: deployment of images and access to storage subsystem.

Due to the characteristic of the jobs (runs in hundred of CPUs a few days) its impossible to use more conventional access to the resources.
