Supercomputing facilities

Onera has two large shared intensive computation facilities:

The “Iseran” NEC vectorial computer

It comprises ten 8-processor SX8R nodes (peak unit power of 35.2 Gflops) and 128 Gbytes of shared memory, giving a total of 80 processors, 2.8 peak Tflops, 1280 Gbytes of memory. The computer has a shared local disc space of 20 Tbytes.

It was commissioned in April 2006, and its power was increased in July 2007 and November 2008.

“Stelvio” SGI ICE 8200 EX superscalar computer

This computer was commissioned in November 2009 and upgraded in April 2011. It comprises 560 computing nodes : 384 computing nodes have two 2.8 GHz quad-core 2,8 GHz Intel Xeon X5560 (Nehalem) processors and 36 Gbytes of memory. 160 computing nodes have two 3.06 GHz hexa-core Intel Xeon X5675 (Westmere) processors and 48 Gbytes of memory. 16 computing nodes have two 2.8 GHz quad-core Intel Xeon X5440 (Harpertown) processors and 32 Gbytes of memory.

The nodes are linked by an Infiniband interconnection network.

The computer has a fast access (Lustre) to a shared local disk space of 300 Tbytes.

The Stelvio computer thus has 5120 cores, 21.7 Tbytes of memory and delivers 59.3 Tflops of peak power.
