The node of Scuola Normale Supeiore in Pisa tolds, manly, three high-performance computing (HPC) clusters for compute intensive workloads.

Name Engineered by: N. Server Blades: Processors on each server blade N. cores Network Memory
CRAY CX-1 CRAY 8 2* CPU Intel Xeon QUADCORE X5550@2.67 GHz 64 Gigabit/Infiniband 192 GB @1333 MHz
A E4 7 4* CPU Intel Xeon QUADCORE E5520@2.26 GHz 112 Gigabit 168 GB @1066 MHz
B DELL 9 8* CPU Intel Xeon QUADCORE E5650@2.67 GHz 432 Gigabit/Infiniband 864 GB @1333 MHz

The most recent acquisition is a an independent chassis with a single unit made of 4 AMD Opteron 12-CORE 6176SE processors at 2.3 GHz with 128 GB of RAM and 2 SATA II hard drives (250 GB + 2 TB for disk-intensive applications).
